 80. Iowa City : A. .1. Hershire and Co. — This little book, the 

 author says, is intended for the use of the students in his class. 

 He has therefore presented briefly only a few fundamental 

 methods, selecting those that he is in the habit of recommending 

 and confining his attention to one or two only under each section, 

 mentioning but three stains out of the almost innumerable array 

 of reagents. Special attention is paid to the bibliography of his- 

 tological methods, references being given under each head, with 

 blank space left to be filled by the pupil if additional references 

 are needed. Space for remarks and notes is also provided. The 

 author treats of injecting, hardening, embedding, sectioning, stain- 

 ing, clearing, and mounting.
