THE USE OF BOOKS. 335 



Handbooks (Chapman & Hall, 193, Piccadilly) which relate to 

 various departments of Zoology, will also be found useful. 

 The student who requires a popular book on Natural History 

 will find much that is useful in Cassell's Popular Natural 

 History, last edition, edited by P. Martin Duncan, .F.E.S., or 

 in Warne's Royal Natural History, edited by E. Lydekker, 

 F.Z.S. 



For reference regarding questions of theoretical physiology 

 which may puzzle the student of Zoology, the article on 

 Physiology in the Encyclopcedia Britanniea, and McKend- 

 riok's Text-Booh of Physiology, afford information in a readily 

 intelligible form. Information on details of histology should 

 be obtained from Quain's Elements of Anatomy, vol. i., partii. 

 Histology, by E. A. Schafer (10th ed., 1893 ; Longmans : price 

 6s.) The advanced student who requires information regard- 

 ing methods of preparing specimens for the microscope, 

 may consult 2'he Microtomist's Vade-Mecum : a Handbooh of 

 the Methods of Microscopic Anatomy ; by Arthur BoUes Lee. 

 2nd ed. Churchill : 1890 : price 8sl 6d.
