TEACHING PARASITOEOGY 
217 
If this suggestion were to be carried out, it would mean that the 
work in zoology offered to veterinary students in most of the de- 
partments of zoology in the various institutions in the country 
would have to be especially outlined for veterinary students, as 
any one of the various studies for beginners in zoology offered 
to students in other courses is too limited in its scope and is 
arranged as one of a series of studies — one being prerequisite to 
the other. To overcome this difficulty departments of zoology 
should offer work to veterinary students complete in itself and 
outlined to meet as nearly as possible the special needs of the 
student pursuing work in veterinary medicine. 
CEASSIFICATION OF ANIMAE PARASITES 
Inasmuch as there seems to be no better way for veterinarians 
it is undoubtedly absolutely essential that we should classify and 
study animal parasites as they are classified in systematic zoology. 
The veterinarian should be able to place in its proper zoological 
position any known parasite. After the student has become fa- 
miliar with the zoological grouping of the various forms he* will 
be able when engaged in the practice of veterinary medicine to 
deal without confusion with parasites according to the species of 
animal attacked or according to the part invaded, for example, — 
intestinal and lung parasites; but unless the individual concerned 
is able to place the parasite under consideration in its proper 
zoological position, he will not make much progress in a scientific 
way. The proper classification of a parasite is, of course, more 
or less essential to diagnosis, treatment and prevention. The var- 
ious forms of animal life to be dealt with in parasitology offer a 
very definite and characteristic morphology as well as conform to 
definite biological laws, therefore, we would emphasize that the 
various forms of animal life found parasitic on our domestic ani- 
mals should be looked upon as groups of disease-producing agents 
to be classified and studied as thoroughly and systematically as are 
microorganisms. When the student has completed the study he 
should look upon and have an understanding of animal parasites 
as comparable with that which would be expected of a student 
completing studies in pathogenic microbiology, or of a student of 
systematic and economic entomology. 
THE GROUND TO BE COVERED 
The subject matter of the study of parasitology should be cov- 
ered by means of lectures, laboratory work, demonstrations, and
