IV PEEFACE. 



In the general arrangement of the contents of 

 the book, I have followed the plan adopted by 

 Dr. Davaine, of dividing it into three parts, so as 

 to keep the description of the different species of 

 Entozoa distinct from the pathology and treatment 

 of the affections occasioned by their presence. I 

 have added a short Glossary of the principal terms 

 employed, both with the hope that it may prove 

 useful, and also in order to avoid the frequent 

 repetition of explanatory notes.
