Those who have to undertake investigations regarding Tsetse-Flies have hitherto been heavily handicapped by the fact that a great deal of the most important literature on the subject occurs in the form of reports and memoirs which have been published in numerous scientific journals. At the request of the Imperial Bureau of Entomology, Major Austen undertook to epitomise this scattered information, and he has executed the task with a master's hand. The result will be of great service to investigators, since the book describes briefly what facts regarding the life-history of these flies have already been ascertained, and what are the directions along which new information is to be sought. After an introduction in which the importance of the study of Tsetse-Flies is emphasised, the author deals in turn with every point of importance in connection with the life-history of these diptera, including distribution and classification, their relationship to big game and the smaller animals, methods of limiting and destroying Tsetse-Flies, prophylactic measures, methods of collection, keeping, and preservation, etc. In addition to nineteen figures in the text, there are excellent plates of the five most important species of Glossina.
Das Meerschweinchen, seine Zucht, Haltung und Krankheiten. Von Professor Dr H. Raebiger, Direktor des Bakteriologischen Tnstituts der Landwirtschaftskammer fUr die Provinz Sachsen in Halle a. Saale, unter Mitwirkung von Fachleuten herausgegeben. Mit. 23 Abbildungen. Hanover: M. & H. Schaper. 1923.
This little book (155 pp. crown 8vo) is as unpretentious in appearance as the animal of which it treats, but, that notwithstanding, it conveys a great deal of information that is likely to prove valuable to those who breed guinea-pigs for profit or amusement, or who have to use them for experimental purposes. It is a model work in respect of the arrangement of the matter, the conciseness of the language, and the completeness with which the whole subject is handled within the limits of space which the author has allowed himself. The opening chapter, which deals with the natural history of the guinea-pig, discusses its probable relationship to wild species still existing in Central or South America, and gives interesting facts regarding its introduction into Europe in the sixteenth century. The succeeding chapters deal with the principles of breeding, feeding, and housing; and the final part, amounting to nearly half of the book, is devoted to the infectious and other. important diseases to which guinea-pigs are liable.
