The Mickoscope. 381 



9. Kecords of our earth's history, etc., so that a careful reading, 

 with the specimen in hand, will give the pupil a very clear and com- 

 prehensive '^knowledge of this interesting class. The writer evi- 

 dently appreciates the importance of pictures to the young, for the 

 work is profusely illustrated, and. although we recognize many old 

 friends among the cuts, — 278 of them, — their value is not lessened 

 by repeated use. We feel sure that Animal Life will be a welcome 

 addition, not only to the primary and common school library, but 

 also to many a home where truth and knowledge have ascendency 

 over the raft of chip-dirt and fiction which flood the country with 

 their demoralizing influence. 



The Physicians' Leisure Library, 1887. Detroit, Mich: Qeo. S. Davis. 

 Single copies, 35 cents. 



Two more numbers of this very handy and excellent series of 

 modern books have been received. No. 3, " Diarrhoea and Dysen- 

 tery; Modern Views of Their Pathology and Treatment," by A. B. 

 Palmer, M. D., is an excellent and exhaustive essay on these common 

 pathological conditions. The careful details of treatment make it a 

 particular value to the practising physician. 



No. 4, the second volume of "The Modern Treatment of 

 Diseases of the Heart," by Desjardin-Beaumetz, treats of diseases of 

 the aorta. The subject of aneurism is extensively considered, and 

 the chapters on its treatment by electrolysis are of the greatest 

 value. This mode of treatment demands the attention of all physi- 

 cians who have to do with this grave disorder. 



Cantor Lectures on the Microscope. By John Myall, Jun. London: 

 1886. Philadelphia: James W. Queen & Co. pp. 97. 



These lectures, five in number, were delivered during the latter 

 part of the year 1885, before the Society for the Encouragement of 

 Arts, Manufactures and Commerce, and attracted considerable 

 attention at the time. Mr. Myall is well known to microscopical 

 science, and ably fitted for the work he had undertaken. The 

 lectures comprise a history of the microscope fi'om the earliest times 

 to the present day, with many observations and criticisms by the 

 writer. Here are figured many curious cuts of the grotesque and 

 clumsy instruments of the 17th century; the ornate, though more 

 useful ones of the 18th century; and finally, the compact triumphs 

 of the present day. The text is clear, and shows the result of much 

 research. Altogether these lectures can be recommended as proba- 

 bly the best compend of the history of this valuable instrument.
