CLINICAL CHRONICLES. 
By A. Liautard, M.D., H.F.R.Y.S. 
Veterinary literature is rich in the history of every variety of 
tumors. Many records can be found in the pages of the numerous 
veterinary journals, of various growths, from the most benignant 
to the most malignant neoplasms. There are, however, some 
which are so rare that a veterinarian may seldom, and some kinds 
which he may never meet with, and if he does, it becomes his duty 
to record them, and give his colleagues the benefit of his observa¬ 
tions. Our researches through a large library of veterinary works of 
various countries having failed to show us any record of dermatoid 
tumors per se; and having had the opportunity, through the kind¬ 
ness of Dr. Cattanaeh, of New York, to examine two in one sub¬ 
ject, we are gratified in being able to present their history to our 
readers, together with the report of one case which happened in 
Dr. C.’s own practice. We notice these cases not so much on 
account of any great interest they may possess in respect to 
questions of treatment,- as to place on record a case, which, though 
it had been already observed by Dr. C., and by ourselves, has not so 
far we can ascertain, found its way into the veterinary journals. 
RARE DERMATOID TUMORS IN THE HORSE. 
The subject was a half thorough-bred saddle mare, which was 
brought to the Doctor for a large lump which had appeared on 
the left side of the body, a little behind the shoulder near the pos¬ 
terior border of the olecranon border. This tumor was in form 
irregular, somewhat lohulated, elongated upwards, slightly mov¬ 
able and not painful. The Doctor started to cut down upon the 
enlargement with a view to its removal, but thinking that it would 
be instructive to the students of the American Veterinary College, 
he had the kindness to have the horse at once brought to the 
hospital. On his arrival the animal presented the conditions al¬ 
ready described. A long incision was made in the whole length 
of the tumor, in a downward direction, and a dissection for¬ 
ward and backward, allowing the removal of a tumor about the 
size of an English walnut.* As the first incision made by Dr.
