AUTHOR'S PREFACE. 



HISTOLOGY has, in the course of a few decades, triumphantly 

 won its field ; it has become an integral part of medical 

 studies. The hand-books have necessarily become constantly 

 more voluminous, in consequence of the immense wealth of 

 materials. 



A short compend of the most essential facts is desirable for 

 students and practicing physicians. I have often heard this 

 wish expressed. 



May the attempt, which I herewith venture, be, therefore, 

 indulgently received. The defects of this little book are very 

 well known to the author.
