The parathyroid glands have been recognized in all classes of vertebrates with the exception of fishes (1). As a rule there are four distinct glands so situated with regard to the thyroid gland that they have been referred to as the superior or external and the inferior or internal pairs. Sandstrom (2) was the first to describe the superior pair. For some reason or other they were forgotten until eleven years later - 1891 - they were rediscovered by Gley (3). The inferior pair were described by Kohn (4) in 1895. Accessory parathyroid tissue is sometimes present and may be …  Lire la suite

With few exceptions the Christian passages in Beowulf are very short. However, their importance lies not so much in this fact as in their frequency which imparts a truly Christian atmosphere to this heathen poem. None of these allusions tell of Christ, the Atonement, or the miracles, but they are of the Old Testament stories, for example, of Cain, and of the Flood, yet they bear the spirit of Christianity insomuch as even these ideas would not have been familiar topics if the author had not been enlightened by the new faith.

The structure, preparation and properties ot the Cellulose Ethers have recently became an increasingly important subject for technical and theoretical research. Previous to the last decade these interesting derivatives of cellulose constituted a practically unexplored field. The only ethers which had been at all thoroughly investigated were the methyl and ethyl celluloses, and only theoretical importance was attached to them. They have served to provide, however, in the capable hands ot Irvine, Haworth, and other workers, a most efficient tool for the investigation of the structure of carbohydrates and polysaccharides.

During the past fourteen years, Kohler and his students (1 ) have prepared a series of substituted cyclopropane in order to determine the effect of the substituent groups on the opening of the ring by various reagents. The valuable information so acquired, has made it possible, in many cases, to predict the probable behaviour of substituted cyclopropane with the various reagents used to open the ring. In eyery case investigated all three carbon atoms of the ring bear substituents. Recently, however, a method has been devised (2) for the preparation of cyclopropane ketonic derivatives which have one carbon atom unsubstituted. …  Lire la suite

The study of the chemical processes concerned with muscular movement can be followed in two directions. In the first place, we may study the structure of the muscle itself, and the mechanics of its operation. Secondly, we may study the energy supply of the muscle, its source, and the manner in which it is made available. Our knowledge of the energy supply of the muscle has developed to the extent, that, in al1 probability, we know more or the reactions taking place in the muscle cells than of those in any other cells of animal tissue. The muscle as a …  Lire la suite

The role of marine bacteria in the economy of oceanic life is little known, although increasing attention has been devoted to its study since the latter part of the 19th and the beginning of the 20th century. This increased interest has not resulted in any etailed study of the physiology of marine bacteria as a group, nor has any attempt been made to classify them. No decisive information can be gleaned from the literature as to the probable position that marine bacteria may occupy in the scheme of living oceanic life or in the cycle of the decomposition of its …  Lire la suite

Social Insurance has been defined as "The method of organized relief by which wage earners, or persons similarly situated, and their dependants and survivors, became entitled to specific pecuniary or other benefits, on the occurence of certain emergencies." It should be added that to be 'insurance', the method used must be on an actuarial basis, although it need not be contributory. There are four main emergencies which Social Insurance is designed to provide against, namely: industrial accidents, sickness, unemployment and an impecunious old age. I shall in this monograph deal, first, with the theoretical aspect of Social Insurance, and, secondly, …  Lire la suite

Seasonal fluctuations of industry, much more than is generally realized, play a major part in the total composite problem of unemployment and distress. The wide range of the Canadian climate, both in time and place, both regular and irregular, throughout the Dominion, has always exercised a restrictive influence on Canada's economic and commercial life. Seasonal fluctuations, particularly in agriculture, construction, forestry, traffic and trade, inevitably mean a seasonal rise and fall in the volume of employment, which in turn entails variations, in time and place, of purchasing power.

Although the active immunization of monkeys against poliomyelitis has been attempted many times with attenuated and chemically inactivated poliomyelitis virus (Landsteiner andLevaditi, 1910; Kraus, 1911; Zappert et a1, 1911; Abramson and Gerber, 1918; Aycock and Kagan, 1927), success has only been achieved with virulent virus (Flexner and Lewis, 1910;Aycock and Kagan, 1927; Stewart and Rhoads, 1929: Rhoads, 1930). However, the danger of infection occurring juring the course of treatment is ever predominant (Thomsen, 1912; Aycock and Kagan, 1927). Therefore, the purpose of this work was to attempt active immunization with active cord virus obtained from monkeys prostrate with poliomyelitis, in …  Lire la suite

A study of the literature on stomata shows that although the earlier workers on this subject were cognisant of the effects of external conditions, such as humidity, temperature, etc., on stomatal movement, their observations in regard to these were of a more or less incidental nature. Darwin ( 3 ) came to the conclusion that a high temperature had atleast some effect in keeping stomata open and that it delayed nocturnal closure. [...]  Lire la suite

Before a proper comparison can be made of the work, the intentions, the methods of the older magazines and reviews, it will be necessary to return to the foundation in 1709 and 1711 ot the "Tatler" and "Spectator" papers. EVen before that time we know that small newspapers of a kind had existed, but in 1709 the idea occurred to Richard Steele of publishing a paper which should contain not only the political news but also the gossip ot the clubs and coffee-houses, with some light essays on the life and manners of the age.

In writing on the subject of social Ethics of the Prophets, I have given special attention to the Book of Deuteronomy, because it is admitted by all scholars that this book summarises all that is best and most permanent in the ethical teachings of the prophets. Consequently no treatment of the Ethics of the prophets would be adequate which was not focused on the Deuteronomic summary. It is clear that this social legislation is the result of contributions from many sources and writers living in different centuries. This fact makes the subject both extensive and cpmp1icated.

Lehmann and Neumann (54) first proposed the generic name Mycobacteriumn for the group of acid-fast bacteria, with Mycobacterium tuberculosis - the tubercle bacillus of Koch - as the type species. They mention, however, in a second edition of their work, that Metschnikoff (63) had previously proposed for the tubercle bacilli the generic name of Sclerothrix, with Sclerothrix Kochii for the species of tubercle bacillus. They did not know of this, when they first proposed the name Mycobacterium for the genus, and as Metschnikoff had not accurately defined his new genus, according to the rules of botanical nomenclature, they claim their …  Lire la suite

Kant has argued that being {Das Sein) is not an attribute of objects: for assuming that an object has first been imagined and then endowed with being, it follows that if being is anattribute, the object which is, is different from the imagined object. Since this is not the case, being, therefore, is not an attribute of object. Simmel (1), following Kant, argues similarly about value (Der Wart). The object is the same after it is endowed with value as before. The conclusion, then, is that value is not an attribute of objeots. In this case, value exists only in …  Lire la suite

"Measurement" plays the role of modulator and investigator in many branches of science. In general, it seems to be the avocation of a natural philosopher to enunciate laws, and then by measurement to seek exceptions to them. These usually discovered exceptions and failures of applicability more often than not yield conclusions which may overshadow the fundamental generalization itself. This is very well illustrated in the developaent or the so called equations of state for gases, and the general applications of the theoretical statements usually referred to on the whole as the Kinetic Theory of Gases.

As the title of this thesis indicates there are two problems involved, namely, "Cavitation" and "Divergent Tubes," and although the former may be caused directly by divergence, there are also other causes, so the two problems have been treated separately. In regard to divergent tubes, special attention has been given to their use in connection with reaction water turbines, or as "draft tubes", which is perhaps the most recent and most important development.

The people in the world today are a theatre loving people. Everyone is becoming theatre conscious and the theatre both indirectly and directly is entering everyone's life. The number of theatrical publications, the space devoted to news of the theatre in current periodicals, the great number of amateur groups, organized for the production and study of drama, the interest of the university in providing oourses dealing with the drama both theoretically and practically, not to mention the ever-present professional stage, all testify to what a great extent the interest of the public in dramatic affairs has grown.

No student of the life and literature of England in the nineteenth century can afford to neglect a consideration of the religious upheavals which took place in that disturbed age. While in economics, politics and science entirely new theories were being worked out and presented to the unsettled minds of the public, in art, literature and religion many men were turning back to seek their models in centuries gone by. There is thus a certain connection between the Pre-Raphaelites, the Romanticists and the Tractarians. [...]  Lire la suite

Cholesterol is one of the most mysterious substances found in the living organism. Although universally present in the cells of the body its purpose is still unknown; discoveredby Conradi in 1775 its chemical structure remains indefinite and its analyysis difficult; insoluble in water, still it manages to permeate the whole body and its amount, in bloodand bile, waxes and wanes like the tide with every meal, and with almost every pathological vicissitude undergone by the body. Even the very crystal of cholesterol, for some unknownreason, has a notch in one of its angles. [...]  Lire la suite

The skin and especially the large skin glands of amphibia have been the subjects of much study and discussion since Ascherson's investigations on the skin-glands of the frog in 1840. But in spite of this extensive work, one fails to find very much in the field of the structure of the lateral line organ of aquatic amphibia. It is mentioned often; its distribution is also given, but only a few authors have dealt with its actual structure. Very closely connected with the structure of the organs of the lateral line is its function. [...]  Lire la suite

A word of explanation may be appropriate regarding the title chosen for this thesis. Its selection was made prior to the investigations which are embodied in the text, and was taken chiefly because it expressed a point of view regarding human motivation which seemed to hold possibilities of fruitful exploration. Much has been written about the will, in theology and moral philosophy, so that it seemed idle to add more words on a subject about which past controversy has chiefly succeeded in hanging a thick fog, unless some new way of piercing the gloom lay open.

By submitting 'this thesis to the Faculty of Graduate Studies and Research, the writer thereof makes no pretension or claim to a 'new' contribution to the study of Feelings and Emotions. The forelying work is merely a preliminary and prerequisite inquiry into the subject, being indispensible 'to a more thorough and more definite (and, let us hope, -- a more original) study of the emotional life of the preschool child that the writer of the following began last fall and hopes to contiue at the Nursery School of the McGill University. After serious and logical thought one must eventually come …  Lire la suite

Perhaps the most important problem facing Canada to-day is the problem of the disposal of her wheat. In recent years Canada has forged proudly ahead to become the "granary of the Empire" and the greatest exporting nation in the world. Our jubiliation over the bumper crop of 1928, however, was shortlived because on of the unusual phenomeon that oocured: the crop did not move out as it should have done. After that the piling up of the 1929 crop was not unexpected. [...]  Lire la suite

In order to make this thesis reasonably complete and yet keep within prescribed limits of space, it was considered best not to include any theorems on invariant factors of pairs of quadratic forms, on quadratic differential forms, or on quadratic forms in an infinite number of variables. Although the results included are for the most part well known, some of the proofs are new. Within the range to which this thesis is confined, perhaps no other single treatise has included all the propositions here collected. [...]  Lire la suite

In spite ot the fact that for some time the commercial culture of ornamentals has been carried on extensively in the United States and many European countries, the diseases ofornamental plants have not received any great amount of attention. Until recently this industry in Canada was of little economic importance, but the rapidly developing bulb industry in British Columbia, and such institutions as the Dale Estate, of Brampton, Ontario, impress one as being indicative of the fact that Canada's competition in the field is fast becoming a factor to be reckoned with.

Tobacco, Nicotiana tabacum L., is susceptible to a number of diseases, few of which have been the subject of so much concern and investigation as those pathological conditions due to virus infection. The present century has been productive of much experiment and research on virus diseases. These have resulted in the recognition of two distinct types of symptomatic virus infection, namely, 'yellows' and 'mosaic'. It is the latter type of disease, mosaic, particularly tobacco mosaic, which is dealt with in this paper.  Lire la suite

On March 16, 1928, Sir C. V. Raman ( 1) announced, at a meeting of the south Indian Science Association, that if a transparent substance is illuminated by monochromatic light, new rays, differing in frequency from the incident beam, are to be found in the scattered radiation. This result was soon confirmed by other investigators (2) and it became evident that tbe phenomenon was a very general one. This in brief, is the effect which bears the name of the man who discovered it after years of painstaking work on the problem of light scattering by material media. [...]  Lire la suite

The Whitemud type of sediment is common in that part of Southern Saskatchewan south of the main line of the Canadian Pacific Railway and west of Estevan. Occurrences are known in Western Alberta and Northeastern Montana, and many in Western North Dakota. This paper deals more particularly with the Whitemud as found in Saskatchewan. The geology of the area has been described by Dawson, McConnell and Rose. Davis was the first to make a detailed study of the Whitemud, however. Later, Dyer reported on the structure of the sediments in parts of the area and McLearn is now making a …  Lire la suite

It is no idle assertion that in practically every field of literary composition the Greeks provided the Romans with highly finished models on which to fashion their efforts. Satire, however, the Romans accepted as an independent creation o£ their own; Quintilian says, "Satura quidem tota nostra est,"(l} and considering Quintilian's learning, sensibilityand position in Roman literature, it would not be incorrect to accept his remark as the general opinion held among the literary classes at Rome concerning the origin of satire, and as a well-founded statement for critics of our own day to follow. If, then, we accept Quintilian's statement …  Lire la suite

It is the purpose of this thesis to trace the development of scenery on the English stage from the beginning of drama in church ritual, to the opening of the eighteenth century, by which time the modern picture-frame stage had become the conventional setting in the theatre. Scenery has two main purposes. These are, first, that of utility, by supplying a background for the action, and by reproducing objects mentioned in the text of the play; and, second, that of art, by the giving of pleasure to the eye as well as the creating of illusion. The combination of these …  Lire la suite

Drama is the one art that can call upon almost every device of the sister arts. All the various methods by which an artist may express himself are combined in the art of the drama, for it is a blending of literature, painting, dancing, music and sculpture. But, whereas in the past the art of literature alone was emphasized, today the other arts are regarded as equally important in the production of plays. From 1660, when movable scenery was introduced on the stage, to the present day, the art of' the theatre has greatly developed. It wasduring the Restoration period …  Lire la suite

Although the oral administration of calomel has long been recognized to be of value in ridding the organism of water in cases of cardiac oedema (Jendrassik, 1886 (1) ), the mechanism of this action is still an open question. The experiments herein described were undertaken with the hope of throwing some further light upon the pharmacology of this phenomenon. The results of our studies are considered in respect to both quantitative and qualitative changes in urinary elimination and a comparison is made of the diuresis resulting from the injection of the organic mercury oomplex, novasurol, and that following the inorganic …  Lire la suite

The first part of this thesis is devoted to a general description and a discussion of the results of a series of experiments carried out by the author and Mr. L. O. Cooper in the Hydraulic Laboratories of McGill University. When a new hydraulic turbine or one of unusual proportions is being developed, the present day practice is to build a model of the turbine for operation in a testing flume, and to use the results from this to design the fullsized unit. It has been noticed that tests performed on large turbines built homologous with existing models generally show …  Lire la suite
