PREFACE TO THIRD EDITION. 



THE favorable reception accorded the "Histology" has necessi- 

 tated the printing of a third edition so soon after the first appear- 

 ance of the book that but few changes have been made at the present 

 time ; these consist, for the most part, of slight alterations of the 

 text and the illustrations. 



The opinions expressed by those most capable of passing judgment 

 lead the author to hope that the preparation of the work has not 



been without gain to both teacher and student.
