comprehensive outline of the internal parasites of our 

 principal domesticated animals ; nevertheless, within 

 the limits prescribed, I believe I have so far 

 covered the whole ground as to present an ex-

I indulge the hope that this little volume may not 

 only prove of service to members of the medical and 

 veterinary professions, but also, in a measure, to 

 agriculturists and stockowners, and to other persons 

 more or less interested in the welfare of those quad- 

 rupeds that are directly subservient to man's wants. 

 At all events, it was in this latter view that the 

 editor of The Field suggested the writing of the 

 original articles.
