to science, the fearful results to man and his cattle and 

 horses ensuing from the attacks of these flies gives the subject 

 an importance of the highest character. So that the author 

 and the B. M. trustees are fully justified in devoting a volume 

 of 330 pages to the elucidation of this small genus. 



" A Treatise on Zoology," edited by Prof. E. R. Lankester. 

 Another volume — being the second fasciculus of Part I — of 

 this scholarly, work has been issued, and deals with the 

 Structure of Animal and Vegetable Cells, by Prof. J. B. 

 Farmer, F.R.S. ; the Foraminifera, by J. J. Lister, F.R.S. ; 

 the Sporozoa, by Prof. E. A. Minchin ; and the Infusoria, by 

 S. J. Hickson, F.R.S. 



" Man's Place in the Universe," by Alfred Russel Wallace. 

 A book, the scope of which is sufficiently indicated by its 

 title and the name of its illustrious author. 



" Mostly Mammals,'" by R. Lydekker. Athough this is a 

 gathered sheaf of magazine articles, the interest is continuous, 

 and it contains much matter that will be found highly sug- 

 gestive to the student of evolution. 



" Coccidai of the British Isles," by Robert Newstead, 

 A.L.S. A second volume of this important monograph has 

 been issued by the Ray Society. 



" British Mammals," by Sir Harry Johnston, G.C.M.C. 

 With coloured plates and illustrations by the author. A 

 modern work dealing with the mammalian fauna of these 

 islands has long been a desideratum, and this new volume of 

 the Woburn Library will be welcomed by many. 



Whilst speaking of scientific literature I may be permitted 

 to mention with regret the passing away of the great 

 philosophic writer, Herbert Spencer, whose monumental 

 works clearly demonstrated the universal application of the 

 doctrine of Evolution, and who was almost the last of that 

 band of intellectual giants by which the Victorian era was 

 distinguished. 



By far the most important research of the past year, so far 

 as insect life is concerned, was the elucidation of the means 

 by which that hitherto mysterious African scourge known as 

 " Sleeping Sickness " is disseminated. And this discovery 

 makes the publication of Mr. Austen's book on the Tsetse- 

 flies specially apposite, although as one reads one cannot 

 help regretting that its issue had not been hindered for a few 

 months that it might have included the report of the Royal 

 Society's Commission upon this subject. For it has now 

 been ascertained, I think beyond doubt, that one of the 

 Tsetse-flies {Glossiiia palpalis) is the carrying agent by which
