TUMORS.

Abscesses never form ; there is sometimes a small oedematous 
swelling. The cows stand the operation very well, and the taste 
of the milk is not altered. Evidently the treatment is long, but 
it is so simple that a layman can readily be initiated with it. 
Spirits of turpentine might be used instead of turpinol, but 
would give rise to great irritation and would probably not give 
as good results. 
TUMORS. 
By Robert Formad, V. M. D., Philadelphia, Pa. 
Reid at the annual meeting of the Pennsylvania State Veterinary Medical Association, 
March, 1899. 
The study of tumors constitutes one of the most interesting 
as well as useful chapters in the study of pathology. The in¬ 
terest is not only from- the standpoint of teaching or the exami¬ 
nation room, but also from the practical application for the busy 
practitioner and surgeon who is concerned not in the latest 
views, not in the charms of the microscopical picture that a sec¬ 
tion of the tumor shows to the pathologist, but is more inter¬ 
ested whether that tumor will return or not return after removal, 
and whether that tumor has given or not given any metastasis 
to internal organs, and after the operation has been successfully 
performed the metastatic nodules continue to grow with renewed 
vigor and spoil the result of a successful operation. Your Com¬ 
mittee of Arrangements in assigning me to give this demonstra¬ 
tion, impressed in the most forcible manner that this should be 
not a scientific lecture, for which you have no time, but a dem¬ 
onstration, and in presenting to you this subject, I will endeavor 
to make it as practicable as possible. A few brief remarks, defi¬ 
nitions, and classifications are, however, indispensable to treat 
the subject in a systematic manner. These remarks, I hope, 
will show that even the most scientific surgeon in performing 
an operation does not need to hold the scalpel in one hand and 
the microscope in the other to have success, but every surgeon 
before plunging the knife into the tissues even of the dumb
