SELECTIONS. 



MANUAL OF HISTOLOGY. 



BY C. H. STOWELL, ANN ARBOR. 



Among the various new text-books in microscopy and his- 

 tology, which have appeared during the past five years, few 

 have met with such successful recognition as Prof. Stowell's 

 book. 



Appearing first in 1881, it has now, within three, years at- 

 tained its third edition, which of itself is sufficient evidence of 

 its merit. This book is designed to meet the wants of a certain 

 class of workers and students, who require a reliable guide, 

 sufficiently practical for every day use, well up to the mark of 

 what is recognized as authoritative in matters of science, and 

 at the same time condensed within such limits as to make it a 

 ready book for reference, and of such moderate cost as to com- 

 mend itself to the favor of all. 



It has been my good fortune to have access to quite a num- 

 ber of the best works on these subjects for several years 

 past, and I can hardly describe the pleasure I experienced on 

 my first perusal of this book compared to others. As amateurs 

 we are all prone to fall into the same errors in the beginning, 

 one of the most usual of which is to imagine that a manual 

 must necessarily be a large book in order to be complete. This 

 manual is free from the one objection common to many such 

 works which are really cumbersome, containing the ideas we 

 are most in search of, hidden in voluminous text insufficiently 

 indexed, and requiring a great amount of reading on the part of 

 the student to find the hints he may be seeking. While Prof. 

 Stowell's book is an octavo of nearly 400 pages, its chapters are 

 condensed, in well written language of pleasing style, and well 

 illustrated with 178 engravings. 



After a general introduction and discussion of the optical 

 features of the microscope, he enters upon the description of 



METHODS FOR PREPARING MICROSCOPIC OBJECTS.

 softening, dissociating and normal fluids, hardening reagents 

 for tissues, section cutting, and embedding mixtures, staining,
