PARASITES OF ANIMALS. 59 
s 
Lists of the Parasites of Man and Domestic Animals. 
The number of species of these internal parasites now 
known is upwards of 100. Therefore it will be impossible, at 
this time, to do more than enumerate the species, with their 
principal modes of occurrence, and then describe more fully 
some of the most important kinds, with their effects and rem- 
edics, so far as space will admit. It is hoped that the lists 
will serve as a key or index for those who wish to pursue the 
subject further, in the more extensive works upon this subject.
