ANIMAL MIGROLOGY 



PRACTICAL EXERCISES IN MICROSCOPICAL METHODS 



By 

 MICHAEL F.GUYER- 



Professor of Zoology In The University 



of Crncinnati 



An indispensable book for teacher, 

 physician, student, or novice who wishes 

 to learn how to prepare his own mate- 

 nal for microscopical examination. There 

 are special chapters on the preparation 

 and examination of embryological ma- 

 terial, blood, bacteria, and objects of 

 general interest, and on the collection 

 and preparation of material for the 

 microscopical work in a course in element- 

 ary zoology. In an appendix nearly 

 three hundred tissues and organs with 

 directions for properly preparing them 

 for microscopical study are tabulated. 

 Sufficient account of the theoretical side 

 of microscopy is given to enable the 

 student to get satisfactory results from 

 his microscope.

 practical class work, for which it is most excellently 

 adapted." — America?i Journai 0/ Medical Sciences, 



"The directions are clear and concise, and every stage 

 . ... is described so carefully that it is hard to see how 

 the student can go astray. Physicians who are rusty
