Nietzsche a dit : " L'homme véritable veut deux choses: le danger et le jeu". Quelques années plus tard un français, Jean Giraudoux, a dit dans son article "Notes sur le Sport"(1):"Le sport est le seul moyen de conserver dans l'homme moderne les qualités de l'homme primitif. Il assure le passage de l'ère de pierre passée à l'ère de pierre future. Il se pourra, grâce à lui, qu'il n'y ait aucune trace des méfaits de la civilisation." [...]  Lire la suite

One of the most important of the many difficult problems which the provincial representatives at the memorable Quebec Conference had to settle before the proposed Union of the British North Amerioan colonies could be successfully consummated was that of the financial arrangements. In contrast to the American constitutional convention of 1787, the conferences at Charlottetown and Quebec were held "in camera" with the unfortunate result that the meagre records and available evidence as to their deliberations are very fragmentary. The financial arrangements which the majority eventually decided upon were adopted in resolution form and these resolutions, issued by the Quebec …  Lire la suite

The area here described is situated 70 miles north of Ottawa, on the Gatineau branch of the C.P.R. near the town of Burb1dge, Quebec. It lies within the Laurentlan upland and in that part containing the famous Grenv111e Series of metamorphosed sediments. The field-work was performed in the latter part of the season of 1927, for the Bureau of Mines, Quebeo, in co-operation with the C.P.R. The work was made possible through the kindness of the Consolidated Mining and Smelt1ng Co., who held an option on the area. The object of the work was to make a study of the …  Lire la suite

The chief task of physical chemistry is the application of physical methods to the treatment of chemical problems. These methods offer a new way of attacking the problem of chemical constitution through investigation of the numerical relationships between physical and chemical properties. A consideration of the various physical properties of substances will show that, in general, these may be divided into two classes, -- additive and constitutive. Although all physical properties, except mass, are to a certain extent influenced by the, constitution of the molecule, we call certain properties additive, since each atom has a constant effect only slightly influenced …  Lire la suite

The object of the present investigation was, in part, to find more satisfactory methods for the preparation of organic disulphides, in particular for the preparation of the acid disulphides derived from the alkyl esters of di thio carbonic acid. There are described in the literature a number of methods for the preparation of organic disulphides of the acid type, but none of these can be applied to the preparation, in a pure state, of such disulphides as those obtainable by the oxidation of the higher aliphatic alkali xanthates, which, on account of their physical properties and unstable nature, cannot be …  Lire la suite

The development of what is known as the equation of state is a beautiful illustration of the progressive advance of physical science. First there is the discovery of a general regularity or law of nature through crude quantitative measurement. This is followed by a stimulating a result of more accurate measurements, what might be called second-order deviations come to light. Following these appears a brilliant extension of the mechanical theory to include deviations. The further investigation has merely indicated the limitations of the fundamental assumptions.

The structure of matter has long interested investigators in all branches of science. Only in comparatively recent years, however, has it been possible to formulate any theory giving a claar explanation of the observed facts. Workers in chemistry have studied the interaction of atoms and molecules, and have brought to light considerable information regarding molecular structure: but to the physicist has been left the problem of determining the structure of the atom and the nature of radiation. A close relationship exists between these two problems and a number of methods of approach have been employed by different investigators. [...]  Lire la suite

The earliest work on the chemical properties and constitution of caoutchouc was done in connection with its destructive distillation. Although it had been noted by Gregory, Dalton, Hirnly and Barnard that such treatment gave rise to oily products, A. Bouchardat (1) in 1837 and G. Williams (2) in 1860 were the first to make a systematic study of these. Williams (2) not only succeeded in isolating isoprene but also noticed that on standing it was transformed into a thick viscous fluid. On distilling the latter he found that, after the unchanged isoprene had passed over, the contents of the flask …  Lire la suite

The study of the digestive canal of tile Gryllidae is full of interest on Eccount of the highly specialized conditions of its different parts. In addition, the abundance of theseinsects renders them very useful for demonstration in the classroom. Many good papers have been published on nearly related insects. Bordas in 1896 published his work entitled "Appareil digestif d' un Orthoptere de la famille des Gryllidae, le Brachytrypes membraneus" and in 1900 published a similar monograph on the anatomy of the Brachytrypes achatinus stoll. We have to give him credit also for many excellent papers on different regions of the …  Lire la suite

Some years ago, the study ef systems containing particles of colloidal size became sufficiently important to warrant the recognition of a new branch ef chemistry. It seen becameevident that these disperse systems ceuld be placed definitely under one of two classes, lyophobic and lyophylic. The properties of these two classes of disperseids are widelydifferent; the mest important distinction, and one to which most of the other differences may be ascribed, lies in the mutual attraction between the disperse phase and the dispersion medium. In a system such as a geld hydrosol, where we have reason to believe that little or …  Lire la suite

The title of this thesis may seem to be somewhat ambitious. By way of apology, therefore, I would point out that I have made no attempt to cover the entire basis upon which Confederation was reared. Several outstanding features have appealed to me. It is on these alone that I touch. My chief concern, naturally, has been a consideration of the economic factors. Yet, so closely related, in Canadian history, are economic and ethnological influences, and so disjointed would any treatment of the subject be without considerable attention being devoted to the latter, that I have taken the liberty of …  Lire la suite

A sales tax is a tax levied upon commodities when they are sold, at a certain percentage of their selling price. It is, really, a general excise tax. While the ordinary, excises are confined to certain particular articles, such as liquor and tobacco, the general excise or sales tax applies to all or a very large number of articles. The most extreme form of general sales tax is the turnover tax, which is levied, usually at a low rate, upon the turnover or gross sales of all dealers in commodities (and often upon the services of professional men as well). …  Lire la suite

The first sample of rubber to reach Europe was sent by a French scientist, travelling in the Andes, to the Academie des Sciences in 1736. Since then, by slow degrees, the civilized world has grown to regard rubber as one of the most useful and indispensable constructional materials in modern life. Since the advent of this substance very rapid advances have been made in the scientific understanding of such subjects as the preparation of rubber from latex on the plantation and the physical properties of raw and vulcanized rubber. Of quite recent years the action of accelerators in vulcanization has …  Lire la suite

One of the main reasons for the study of gums or slimes produced by micro-organisms in the past has been their industrial importance. Such problems as the viscous fermentations ofbeer and wine, ropiness in milk, and slime in bread, drew the attention of investigators to the possible significance of such abnormalities. While it is true that some fermentations are benefitted by viscocity as in the formation of Dutch "lange-Wei", used as a starter in the manufacture of Edam cheese, of "taettemaelk" (thick milk) of Norway and of "Filmjolk" (stringy milk) of Sweden and Finland, it is generally considered that, for …  Lire la suite

The thesis which follows purports to investigate the economic aspects of the Crowsnest Pass Agreement, one of the many strands in the tangled web of Canadian Freight rate structure. The Crowsnest agreement, passed by Parliament in 1897, and invoked today as a Magna Carta by the grain-growing west, is important not only to the wheatgrowing community who demand its perpetual retention, but also to the railways and shippers of other commodities who claim that its terms are working hardships upon them.

Well marked periods of good and bad times really form no part of the economic life of a community until this community has had the advantages or as some wold have it the disadvantage, of modern society. Modernism justly includes a complex industrial life and the dependence of this life on a delicate mechanism of credit. Not of necessity but of reality we must insist that modern society is divided among itself: to follow the sismondi we can call the classes the rich and the poor. [...]  Lire la suite

The acourate determination of specific heats is a matter of some importance in Physics and Chemistry. Divers methods have been used by investigators, each suited to its own particular purpose. In the case of gases, comp1ications arise owing to the existence of two speoifio heats, one at constant volume and one at constant pressure. It oocurred to Dr. Keys that certain experimental methods, which he was using for another purpose, might be adapted to the accurate determination of specific heats of gases at constant volume by the explosion method. Certain facts must be ascertained before this adaption is possible, however, …  Lire la suite

Process cheese is a special form of prepared cheese, the term "process" being applied by Dr. J.A. Ruddick, Dairy and Cold storage Commissioner of the Department of Agriculture. By various processes of heating and emulsifying, well matured cheddar cheese is made into a palatable, homogeneous product, which lends itself easily to moulding-into various shapes,sizes and weights. This bacterial study of process cheese was undertaken to find out the numbers and kinds of bacteria found in the cheese when sold to the consumer; to ascertainthe effect of the pasteurizing temperature on the germ content; and to study those organisms which find …  Lire la suite

The Montreal of 1928 presents a striking contrast to the Ville Marie as founded by Maisonneuve. From its particular geographic location it was destined to occupy a position of dominance in the growth of Canada. The peculiar physiographic features of the St. Lawrence River on the South and Mount Royal on the North have given the direction fo the city growth its own particular form. The phenomenon of th4e two nationalities, diverse in language, traditions, religion and culture, living side by side and paying allegiance to a common sovereign has marked the city with an atmosphere that adds to its …  Lire la suite

Even in the earliest stages of the economic growth of any country, the use of "credit" may be found to have existed, as the means by which, the exchange of goods and commodities was facilitated. Wherever it is found that people began to live together even in the smallest of communities, it is apparent that they have been prompted to exchange their goods with their neighbours. With this exchange of goods there soon grew up the need for a medium of exchange, but it might even be maintained that the use of credit has preceded the the adoption of any …  Lire la suite

Association of plants is by no means a new subject for study, though so far reports dealing with association of phytopathogens have been comapartively rare,as a survey of theliterature on the subject indicates. Most attention has evidently been turned to other branches of research. Recently, during an extensive survey of storage rots at Macdonald College and vicinity, it has been observed by the writer that even though the rots were relatively abundant and many vegetables and fruits were attackedtthe number of speciesof pathogenic organisms on a single specimen was very limited.

A survey of the field of "emot1ons and fee11ngs" is a vast undertaking. Dur1ng the past twenty-five years an annual crop of text-books on Psyohology has been turned out by the press. Each text-book devotes one or more ohapters to an exposition of "emotions"; each writer advances his or her theory; each theory depends upon the particular psychological position of the writer. In general terms one might say that there are only three or four basic theor1es, and from these basic factors many modif1cations have been reared. [...]  Lire la suite

For more than a century, the study of the thoracic sclerites of insects in general, has drawn the attention of several entomologists, and yet there seems to be a need for further investigations in that line. Beginning with the work of Audouin (1824), the morphological study of the thorax has evolved through the contribution of several investigators who have worked from time to time on different groups of insects, or even on the entire class Hexapoda. Martin (1916), wrote a very interesting paper on the subject in which he included a historical review of the literature published until that time. …  Lire la suite
