Miscellaneoits Intelligence. 295 



secondary object is the study of the fungi and insects injurious to 

 the crops and. animals, the analysis of foods, water, minerals, 

 ores and fuels, and all such other matters as pertain to the eco- 

 nomic development of the natural resources of the country. 



The first of these aspects — the medical — is treated in the beau- 

 tifully illustrated quarto volume in hand, while the second aspect 

 — General Science — will be represented by a similar volume 

 shortly to be published. 



The present book consists of some forty separate, but related, 

 papers dealing with the general matters of tropical hygiene and 

 blood examination, with special reports on the recent discoveries 

 relating to the diagnosis and treatment of particular diseases. 

 Especial attention has been given to the means of identification 

 and the study of the life cycles of the parasites involved, and 

 many new and important facts have been discovered. The 

 volume also includes special reports by the Sleeping Sickness and 

 Kala-azar Commissions. 



The results of the work of the laboratories up to the year 1908 

 have been published in four quarto volumes, and the fact that the 

 important researches described in the present report have 

 been accomplished during the past three years emphasizes 

 the remarkable industry of a corps of workers under climatic and 

 other conditions that would seem far from ideal for the most con- 

 centrated effort. w. e. c.

Einfuhrung in die Mykologie der Genussmittel unci in die 

 Gdrungsphysiologie ; von Dr. A. Kossowicz. Pp. viii, 211 ; 

 2 plates, 50 text figures. Berlin, 1911 (Gebriider Borntraeger). 

 The present "pure food movement" and the increased interest 

 in the problems of the preparation and preservation of foods 

 have encouraged the publication of books bearing on these topics, 

 in a form which shall not be too technical for others than the 

 extreme specialist. One of the Kossowicz monographs reviews 

 the nature of the microflora of various familiar products — milk 

 and its derivatives, meat, eggs, and fruits — together with sugges- 

 tions respecting the preservation of them. The second deals 

 with the microbiology of the fermentation industries, the manu- 

 facture of vinegar and mustard, tobacco fermentation, and the 

 biological factors involved in the preparation of coffee, tea, cocoa 

 and vanilla for the market. Though unembarrassed by extreme 

 details, the subject matter is obviously intended for individuals 

 possessed of some scientific and technical training rather than for 

 the layman. An extensive bibliography is included in each 

 volume. l. b. m.
