THE MICROSCOPE AND MICROSCOPICAL METHODS. 



By Professor S. H. Gage, of Cornell University. Five full page plates and eight figures 

 in the text. 



The New Edition (Fourth) is now ready. 



" It Is np to date, and the sections devoted to Homogeneons Immersion Objectives, the Sub-stage Illumi- 

 nator, the Camera Lucida, the Micro-Spectroscope, and the Micro-Polariscope, will be especially welcome to 

 workers. . . . Altogether it is one of those books that the student and worker in microscopy caunot afford to 

 be without." — The American Monthly Microscopical Journal, December, 1891. 



"If the owner of his first instrument will carefully read this book, and will foVow all the experiments de- 

 scribed by the author, he will find that he has within his reach almost a royal road to the proper uuderstand- 

 ing of the microscope, of its manipulation, and of the elementary preparation of objects, althouj^h the latter 

 is exceedingly concise and somewhat meagre." [Full directions for preparing specific objects will be givoji 

 with Part II, in course of preparation.] — The Microscope, December, 1891.
