A study has been made of the physiological properties of the thyreotropic hormone of the anterior pituitary. Evidence of hyperfunction of the thyroid has been shown to occur in the rat and guinea pig following injection of the hormone. The toxins of staphylococcus aureus accentuate the effect of the thyreotropic hormone in the rat. Replacement therapy has been accomplished in the hypophysectomized rat with the thyreotropic hormone. A study has been made of the resistance to the hormone which develops in animals after prolonged injections. A substance which inhibits the action of thyreotropic hormone has been found in the serum …  Lire la suite

A new method of studying the acidity of the organic matter of podsol soils has been developed. The soil solution is displaced with distilled water from soil placed in glass percolators, concentrated on a steam-bath and dialysed through cellophane. Analysis of the dialysate has shown that up to 50% or more of the acidity may be accounted for as sulphuric and phosphoric acids. At any one time, 100 to 300 lbs. of sulphuric acid and 15 to 50 lbs. of phosphoric acid per acre may be present. [...]  Lire la suite

An attempt was made to investigate the oxidation of zinc ethyl by the method of ~dilute flames". However, no flame could be obtained even at quite high temperatures and pressures. Furthermore, there was no evidence of any reaction whatever at the low pressures used. The oxidation of zinc ethyl is always accompanied by the deposition of a white precipitate,and this could not be observed. [...]  Lire la suite

Methyl cyanoacetate, cyanoacetarnide and malononitrile all gave trimolecular products when added to phenyl vinyl ketone. Nitromethane gave a tetramolecular compound. Methyl cyanoacetate gave methyl 1,5-dibenzoyl-3-cyanopentane-3-carboxylate which, when treated with hydrogen bromide, gave the corresponding amide, an "imide bromide" and methyl 2-bromo-3(B-benzoylethyl)-6-phenyldihydropyridine-3-carboxylate.

Among the various constituents of personality, temperament is generally recognized as that something inborn and permanent which has always been linked with bodily characteristics.The classical doctrine of four temperaments, left practically unchallenged until the beginning of this century, is now superseded by several new ones. Their theoretical basis differs, but they agree fairly well in considering temperament as a factor whose variations could be distributed on a continuum, ranging from an extreme type to the diametrically opposite. Jung's appellation of these types as introvert and extravert is the most widely used nowadays. [...]  Lire la suite

The requisites of a sound system of social economy are maximum production and the most equitable distribution of wealth consistent with it. It is the contention of the writer that no radical departure from the present economic organization which is based on the individual's pursuit of profit as the main economic motive - is necessary to secure this. The outstanding impediment to the realization of maximum production is seen to be industrial depressions and the enforced idleness they cause. An analysis of depressions reveals that price stabilization holds the key to the solution. But the present technique of regulation cannot …  Lire la suite

The phenol condensation products of the "native" lignin found in spruce wood and of lignin isolated by the Freudenberg method have been prepared and their derivatives studied. When wood is extracted with phenol in the presence of hydrochloric acid as catalyst, two chemically different phenol lignins, in approximately equal amounts, are formed. On the otherhand, when a previously isolated lignin, namely Freudenberg lignin, is subjected to the same treatment, only one phenol lignin derivative is produced and in a nearly quantitative yield, showing that there is a difference between "native" lignin and an "isolated" lignin. The results of the present …  Lire la suite

The contract of employment in all its implications is dealt with in the light of the Quebec Civil Code, other statutory enactments and jurisprudence. Employers' liability at common law, while superseded, to a certain extent, by workmen's compensation legislation, still plays an important part in the employer-employee relationship. It was treated on the basis of the Quebec Civil Code and jurisprudence, preceded by a survey of employers' liability in Great Britain, as a background. The provisions and practical operation of the Workmen'sCompensation Act, 1931, received thorough consideration. The study is based on the statute, material published by the Workmen's Compensation …  Lire la suite

The source of cells which give rise to the new tissues and organs in regeneration has been described in a large number of animals. In Section I a review of the literature dealing with this subject in a number of groups of animals - Amphibia, Reptiles, Mammals, Oligochaete and Polyehaete Annelids, Nemerteans, Sponges and Coelenterates - will be made. The source of the cells which proliferate new cells in the growth of certain tissues - Epidermis, Retina, Muscle, Notochord, Cartilage and Gut, as well as intravascular multiplication of Erythrocytes - will be dealt with in Section II. This will embrace …  Lire la suite

In this paper experimental results are given of the temperature distribution in steel plates during welding. The results obtained are compared with those given by the Mathematical Theory of Heat Flow. The plastic and elastic strains, caused by the temperature history of a square plate with a weld applied to one edge, were measured. These strains were found in directions parallel and perpendioular to the welded edge. [...]  Lire la suite

This thesis contains some Polish, Slovak, Serbian, and Finnish ballads, collected in America and rendered into English for the first time by the author. There are also some translations of the Finnish ballads from the Kanteletar of Elias Lonnrot. A brief summary of the theories of poetic origins is given, some additional corroborative evidence in behalf of the communal theory of ballad origin included, and a reasonable comprehensive theory suggested. Similarities and differences in form and material among European ballads are analysed. A description of the later history of the ballad concludes the discussion.  Lire la suite

Under mechanical conditions is included pre-treatment of the wood with a view to bringing about controlled conditions of penetration of the cooking reagents into the wood. [...]  Lire la suite

A study of the literature dealing with ball milling, a part Bibliography o£ which is given in the Appendix, leads to a first conclusion that considerable research has been undertaken on this subject. However, on closer study, it is apparent that a great deal of the work has been purely academic and of very little use to the practical mill operator. In the first place a large part of the llterature is devoted to the development of mathematical theories of crushing and their approval or condemnation; in the second place much of the practical work performed in laboratories has been …  Lire la suite

An endeavor has been made 1n this thesis to survey the current opinion as to the development of character in physical education. The work has been divided into five chapters. The general introduction points out the necessity of some drastic solution to current problems and suggests that 1n the realm of the behavior relationships of men, many of the most serious difficulties are to be found. The second chapter, dealing with philosophical backgrounds for character education theory encompasses current opinion on definitlons,the goal of education, the various theories of character, and closes with a review of material which shows the …  Lire la suite

Piaget's studies of the child's intellectual development are submitted to critical review and evaluation. The clincial method which he has applied in this fie1d is analyzed and tentatively accepted as a new approach to child study. The central hypothesis of the author is that child thought is qualitatively different from that of the adult: he calls this thought "ego-centric". The author postulates that ego-centric thought is incommunicable because it is not socialized and that it evolves in accordance with the growing need into the logical thought of the adult. This ego-centrism results in transductive reasoning, intellectual and moral realism and …  Lire la suite

Neurogenic hyperthermia is a definite syndrome not infrequently seen in neurosurgical practice. It has been only casually mentioned in the literature and no opinion has been previously ventured as to its etiology. In its most typical form this condition occurs immediately after cranial operations or head injuries as a marked elevation of body temperature with a very rapid cardiac and respiratory rate and a constant unremitting cutaneous vasoconstriction and anhidrosis.

Sap products were examined before and after flavour development. Study of "vacuum"'sugar has shovm that the hadromal theory for maple flavour is untenable; that it yields on extraction succinic acid, an unsaponifiable oil or resin, and an amorphous material with the reactions and composition of lignin, which is probably responsible for the developmentof flavour, but as isolated cannot be direotly converted into it.

Immigration is intended as an adjustment from one set of conditions to a more satisfactory environment. This thesisattempts to cover the adjustments in the means and modes of living of two irmnigrant groups in Montreal, Canada, the Italians and the Finns, and to present several general hypotheses concerning the assimilation process in these fields. The effects of the economic depression on these processes are noted. Spatial adjustment and chances in family organization are included in so far as these relate to our main points of reference. The principal source of information has been the family budgets of representative samples of …  Lire la suite

This survey, which is primarily concerned with Great Britain, presents various accounts and explanations of the economic fluctuations experienced between the years 1800 and 1914. Quotations from annual reviews, periodicals and a few histories make up the greater part of the work. Most of the extracts given are from writings composed at a time contemporary to, or shortly after the occurrence of the events discussed in them. The purpose of the study is to indicate economic conditions in the period considered, and to assist in reaching a clearer understanding of the nature of economic f1uctuations. [...]  Lire la suite

An investigation was made of the chemical compounds formed between metallic sulphides, especially pyrrhotite and pyrite, and alkalies as commonly used in the grinding circuits of Sulphide Flotation Mills. The effect of oxidation on these minerals was examined. Experimental Tests were made to determine the resultant action of these compounds upon chalcopyriteflotation. A hypothesis has been advanced, and experimental evidence produced, for the necessity of pre-flotation aeration in mills treating heavy sulphide ores.  Lire la suite

The extraction of "glycol lignin" by use of glycol containing 0.05% HCI has been investigated, new methods for the purification described, and the methoxyl contents shown to be 16.5 - 16% (and not 18.5, as previously reported). Fractionation gave two isomeric components. The indirect evidence for the presence of a glycol radicle in "glycol lignin" has been confirmed. [...]  Lire la suite

The English literature of these provinces begins with the coming, about 1760, of the New England immigrants, who brought with them their own traditions, with their subsequentinfluence. With the Loyalists (1783) came the influence of the late 17th and early 18th century English writers. An attempt is made to show why Loyalist influence upon literature and education ~as not greater. The Pre Confederation period is a discussion of the works of Haliburton and Howe, both in regard to literary value and to public affairs. The Post-Confederation period, in which a definite national sentiment is evident, is represented almost entirely by …  Lire la suite

The Beattie-Galatea area is in Duparquet and Destor townships, northwestern Quebec. The main points of interest are: recent gold discoveries, and a longstanding controversy over the age of some porphyry intrusions. The geological features of the area include an east-west band of Timiskaming sedimentary rocks, with Keewatin volcanic rocks to the north and south of it. It is believed that these formations are closely folded into a synclinorium. [...]  Lire la suite

In comparison with the institutions that have been developed to take care of the marketing of grain, cotton, metals, securities and credit, labour has been almost entirelyneglected. The care and direction of the labor supply are, with minor exceptions, without system; and the few agencies or institutions offering assistance are not co-ordinated into a comprehensive system. Even today very little is known of the methods of search for employment and the extent, duration, and costs to the worker of a period of adjustment. [...]  Lire la suite

As the course is at present arranged in Quebec, arithmetic is the only mathematical subject taught in the seven grades of elementary school.

This thesis, which deals with the last decades of the French regime in Canada, is the first part of a further thesis, which I hope to prepare, dealing with economic and social development in Canada from 1740 to 1770, that is, the transition period from French to English rule. The object of the present account is, therefore, to give some description of just what Great Britain received when Canada was ceded to her in 1763. The most outstanding characteristics of economic activity in French Canada were inertness and government paternalism, the former usually being attributed to the latter. An attempt …  Lire la suite

Various methods are set forth, by which the Theory of Forms may be used to determine the number of roots of an algebraic equation within any region of the complex plane bounded by circles or straight lines. In all cases the principle is the same: we set up an appropriate associated Hermitian or quadratic form, and reduce it to its normal form. [...]  Lire la suite

This paper presents the results of an investigation to determine the inheritance of black and white seed coat colors in alfalfa. The "black" character appeared to have arisen as a mutation in a third generation selfed line. Black x Yellow hybrid progenies in F2 exhibited a wide range of seed coat color extending from normal yellow to dark mulatto. Inheritance proved to be fairly complex requiring the assumption of at least three factors. One gene, primarily responsible for pigmentation of the seed coat, and at least two modifying factors, were postulated as the most probable genetic explanation of the breeding …  Lire la suite

The extension of the North Amerioan frontier into the western plains of the Canadian Dominion in the early years of the present oentury transferred a large volume of the European Trans-Atlantic emigration into Canadian channels. The settlement of such peoples has altered fundamentally the Canadian social milieu. It is in the reaction of the immigrant groups to the culture of their adopted land that we find the dynamics of the assimilation process. That reaction, and the consequent participation or lack of participation of the immigrant in Canadian life is determined by the spatial and occupational segregation of the immigrant group. …  Lire la suite

Alkali lignin was prepared oy heating thoroughly extracted spruce wood-meal in an autoclave with 4% NaOH for 1 hour at 172 °. The crude product, on purification by precipitation from dioxan into ether was separated into two homogeneous fractions, Alkali Lignin A, insoluble in dioxan-ether, and Alkali Lignin B, soluble in dioxan-ether. Alkali Lignin A condensed with both 0- and p-bromphenol to form the corresponding substituted phenyl ethers, which gave identical analyses. On the basis of the bromine content of these condensation products, Alkali Lignin A corresponds to the empirical formula C67H7l023 (m.w.= 1244), and contains, as shown from the …  Lire la suite

This thesis traces the birth and growth of the stream of consciousness method in English fiction, paying particular attention to the way it has been handled by such literary artists as Dorothy Richardson, Virginia Woolf, and the late Katherine Mansfield. Chapter One deals with the growth of Modern Subjective fiction, from the writing of Henry James to that of James Joyce. Chapter Two endeavours to show how Dorothy Richardson has used the method in her series of novels, Pilgrimage. Throughout the ten volumes she has never gone outside the consciousness of her main character, Miriam Henderson. Chapter Three deals with …  Lire la suite

An apparatus has been devised for measuring the apparent adsorption of gases, vapors and liquids on solid surfaoes up to the critical pressure and critical temperature. The systempropylene-alumina has been investigated. There was no discontinuity in the adsorption prooess with a ohange from vapor state to gaseous state as defined by the oritioal temperature.Apparently adsorption did not ocour from the liquid state and there was a marked discontinuity in the adsorption curve with a change from liquid state to gaseous state. This may be due to a differenoe in the forces of attraction between liquid and gas or vapor molecules …  Lire la suite

Gamma ketonic acids of three distinct series have been prepared and their behavior in certain characteristic reactions determined. It has been shown that there is no relationship between the kind of groups present in these acids and their structures. To illustrate this, the action of methyl magnesium iodide and of acetyl chloride has been studied in detail. In the most highly branched series -the acrylio acids- the resemblance of the lactols to triphenyl carbinol has been noted. To account for the action of acetyl chloride, in the other two series, a mechanism for the reaction has been proposed and discussed. …  Lire la suite

The major portion of this paper 1s a taxonomic study of the parasitoidal subfamily Joppinae (Family Iohneumon1dae). Their hosts are species of the family Noctuidae and many of these are of eoonomic importance in the prairie provinces. A taxonomic study of the western joppines, therefore, may be of value 1n biological control work. The methods of increasing the natural efficiency of parasitoids are reviewed, as well as the factors that modify or nullify attempts at control. [...]  Lire la suite

It has been suggested many times that aldehydes were of importance in the oxidation of saturated hydrocarbons. It would be expected that similar conditions would prevail during olefine oxidation.
