The purpose of this study is to examine in detail certain international conventions in the field or air law with a view to determining under what conditions international air carriers are responsible for the acts of agents and servants. The agreements considered are the Warsaw Convention (12 Oct. 1929), the revision of the Warsaw Convention proposed at Rio de Janeiro (Sept. 1953), the second Rome Convention (1 Oct. 1952), and the Draft Convention on Aerial Collisions (12-22 Jan. 1954, Paris). Other treaties will be treated incidentally.  Read more

The use of the external anatomy of the larvae of bark beetles for the purpose of generic and specific identification has been neglected in the past. One reason for lack of interest in this particular phase of the study of bark beetles may lie in the biology of this group of insects where, in many cases, adults are present together with the larvae throughout most of the developmental period. However, there are occasions where larvae of more than one species feed in the same area of bark, and even though adults of all species represented are present, the percentage of …  Read more

Twenty-five years ago a geomorphologist, N. M. Fenneman, discussed what he called “the circumference of geography”. On that circumference Fenneman placed climatology, biogeography, commercial geography, political geography, mathematical geography, and physiography (geomorphology); all of which overlapped, in both data and techniques, the territories of related disciplines. If geography consisted of no more than an aggregate of these peripheral subjects, said Fenneman, it would have little right to exist.  Read more

The present investigation was undertaken to study the etfect X-irradiation on the sex ratio of the offspring to irradiated male mice. It also appeared worthwhile to find out whether nitrogen mustard would exert etfects similar to those suspected of X-rays on sex ratio (Kalmus et al, 1952), since many of the effects nitrogen mustard exerts on the living organism are strikingly similar to the effects of radiations(Boyland, 1952; Bastrup-Madsen, 1951).  Read more

Compulsory insurance to cover the carrier's liability in air transportation has been debated for a number of years. Notwithstanding the fact that the various international conferences have not, as yet, arrived at a definite decision, the discussion upon the subject matter is by no means closed.  Read more

The electrode shapes for a Pierce type electron gun as determined from an electrolytic tank have been inveatigated experimentally. The deterioration in performance for a known deviation of potential along the beam edge within the gun was measured. Pure tungsten wire spirals used as emitters were inveatigated using both D.C. and A.C. heater power and the effect of heater polarity on gun performance was measured. [...]  Read more

Despite the formation of the German Empire in 1871, Germany remained, in theory at least, a federation of the larger German kingdoms, each of which could have its own relations with foreign powers. The British Government naturally conducted its business with the German Empire through the Imperial Foreign Office at Berlin, but it nevertheless found it extremely useful to keep a minister at Munich-Stuttgart. It may be remembered that, while this minister had not the rank of an ambassador, his office was not a mere appendage of the Embassy in Berlin, in the manner of consulates of to-day. It had …  Read more

The organs of the adult animal may generally be divided into two broad groups on the basis of their mitotic activity. In one group, including liver, kidney or adrenal medulla, mitotic division of the parenchymal cells occurs very rarely. In the second group, comprising the hemopoietic tissue, gastric and intestinal mucosa, epidermis and other tissues, there are numerous dividing cells even in the mature animal. [...]  Read more

Cleft palate is a common congenital anomaly, and it is dealt with by a variety of scientific groups. The medical profession is concerned about cleft palate because it is of sufficiently frequent occurrence to distress many people. Knowledge of the mechanisms and materials involved in palate development might be useful in designing preventive measures for prenatal care. The cleft palate condition is of interest to embryologists because it so often turns up in the list of defects caused by various teratogenic agents, and a better understanding of this defect would help in assessing the specific defects of a teratogenic substance.  Read more

The so-called age of antibiotics is generally considered to be of recent origin but the foundation of its beginning goes back to the last century. The phenomenon of antibiosis, the production by one organism of a specific chemical substance or substances which have an injurious effect upon another organism, was noticed by many of the early microbiologists. Although Tyndall, Pasteur, and DeBary worked in different fields of biology, each mentioned this phenomenon of antibiosis in his writings.  Read more

Muscle activity may seem a topic far removed from that of attention. However, the recognition of motor phenomena during thought pervades the history of experimental psychology. In a recent review of this subject, Humphrey describes the recognition given to tensions in the muscles during thought by both the Wurzburg and Cornell group of introspective psychologists. [...]  Read more

Man's attempts to answer the seemingly eternal question 'Am I my brother's keeper?' have furnished fuel for the fires of philosophical discourse since the beginnings of recorded time and probably will continue to do so ad infinitum. For, tangled in its roots lie the complex, controversial theories of 'natural law' and out of its twisting branches stem the ideas of the 'natural rights of man'.  Read more

Schillers Stellungnahme zu Goethes Egmont hat zwei literarische Niederschlage gefunden. Am 20. September 1788 veroffentlichte die Allgemeine Literatur-Zeitung, Jena, Leipzig und Wien, in ihren Nummern 227a und 227b, Spalte 769 - 778, Schillers Rezension des Egmont unter dem Titel: Uber "Egmont', Trauerspiel von Goethe. Der Druck der Rezension wurde wiederholt in "Kleinere prosaische Schriften von Schiller", 1802, 4. Theil, 5. 243 - 267. Schliesslich fand die Rezension Anfnahme in den "samtlichen Werken", 17. Band, Carlsruhe 1819.  Read more

The phenomenon of parasitism is encountered in all phyla of living creatures - vegetable and animal - from the largest to the smallest, from the most primitive to the most complex. Parasites themselves range from free-living ectoparasites such as fleas and ticks through to those absolutely host-dependent endoparasites such as trypanosomes and endamoebae.  Read more

Jusqu'en 1938 la poesie jouissait, aux yeux du public lettre du Canada francais, d'un prestige bien superieur a celui du roman. Cependant, a partir de cette date, (celle de la publication de Trente Arpents) au Canada francais comme partout ailleurs, le roman se mit a gagner rapidement du terrain sur la poesie. Vers 1950 il devait eclipser cette derniere en qualite comme en tirage.  Read more

Work done previously in this Laboratory by G.N. Milford showed that the extraction of black spruce chlorite holocellulose with liquid ammonia removed about 5% by weight of the wood, and at the same time made soluble in water 12.7% of polysaccharide material that previously had been water-insoluble. The water-soluble polysaccharide fraction contained xylose, arabinose, galactose and uronic acid units. The residue from the extractions with liquid ammonia and water represented 55.8% of the wood and retained a substantial amount of hemicellulose, including almost all the mannan. [...]  Read more

The ovary has been recognized as an endocrine organ for many years. This was established in many species, in classical fashion, by removing these organs and observing what occurred in the spayed animals (1). [...]  Read more

A restless world, not yet recovered from the last World War and still plagued with the realities of "limited warfare," is confronted with the problem of restraining the brutality and massive destruction inherent in possible future large scale hostilities. Recent tests of thermonuclear devices have occasioned new and vigorous demands for legal restraints on weapons and methods of warfare.  Read more

The study was undertaken in order to clarify and evaluate the role of the medical social worker in helping patients with skin diseases. This analysis was based on an examination of the hospital and social service records of 30 skin patients who had been known to the worker on the dermatology service at the Royal Victoria Hospital between January, 1950 and March, 1953. Their environments, personalities, and reactions to the illness were studied to determine whether certain factors influenced the worker's role.  Read more

This thesis has evolved from a very great (and to the author, disturbing) interest in the combined fields of social, political and economic change. In a Department where pure theory has been designated as the major, if not the only, area for legitimate economic research, the institutional leanings of P.H.D. students are regarded as curious and perverse. The author is, as yet, unregenerate: the "underworld" of economics still appears a place peopled with interesting, provocative scholars whose point of view yields productive and sometimes profound observations on economic activity.  Read more

The Candego is a small lead-silver-zinc mine in the northern part of the interior of Gaspé. T he ore bodies are narrow high grade shoots plunging at low angles to the west in east-west striking , steeply dipping longitudinal strike-slip faults. These faults cut a strongly contorted zone in the Lower Ordoviclan sedimentary rocks. The minerals in the ore are quartz, carbonates, pyrite, galena, sphalerite, and smaller amounts of chalcopyrite, pyrrhotite, gold, tetrahedrite, arsenopyrite, bournonite, and anglesite.  Read more

At present there is no general scheme or well defined criteria which may be followed in placing an organism within the genus corynebacterium. Morphological and physiological studies to date, have not provided a satisfactory solution. A rather extensive amount of serological investigations has been reported, but is mainly concerned with the type species, G. diphtheriae. The majority of workers has been occupied with typing studies on the 3 cultural groups of c. diphtheriae.  Read more

The effect of mechanical forces on the structure of bone has intrigued biologists for many years. As early as 1838 Ward recognized the resemblance of the structure of the femur to a crane, and the appropriateness of the form of the femur to withstand the possible forces to which it was subjected. Since it has been universally assumed that bone must withstand mechanical forces, many investigators have analysed and tried to relate the structure of bone to the manner in which these forces are distributed throughout the bone.  Read more
