REPORTS OF CASES. 
has been for a number of years under the observation of Dr. J. 
Dougherty, of New York City, and was sent by him to the hos¬ 
pital of the college for clinical instruction to the students. 
Affected with severe difficulty of breathing, and roaring even 
when at rest in his stall, this gray gelding, about twelve years of age, 
had some three and a half years previously presented on the right 
parotid gland an enlargement, the true nature of which was not 
then made out, but which, under treatment by severe blistering, 
seemed to have somewhat subsided. It however, soon appeared 
to have regained its former size, and continued to enlarge. 
About four months ago another swelling began to show itself in 
the left side, rapidly increasing, and extending from the base of 
the ear down to the lower extremity of the parotid. The enlarge¬ 
ments of both parotid glands had assumed the general external 
appearance of melanotic tumors, and the fact of their interfering 
with the respiration had rendered any possible treatment out of 
the question. The poor animal, which was apparently otherwise 
in perfect health, was destroyed. 
From the general condition and age of the patient, and the 
enormous size of the parotid growths, it was supposed that lesions 
of general melanoemia would be found on the post-mortem exam¬ 
ination, but this did not prove to be the case. On the contrary, 
every organ of the splanchnic cavity was normal, and no melanotic 
tumor or deposits could be found in any portion of the cadaver, 
except those under the parotid glands. Connected together 
under the cranium, and opening in the guttural pouches, laudable 
pus of a thick consistency was found. The tumors, when removed 
and isolated, weighed four pounds for the right, and three pounds 
for the left side. But besides these lesions, another no less inter¬ 
esting, was discovered. This consisted in a fracture of the long 
branch of the hyoid bone on the left side, with an absorption of 
a portion of the bony structure. The two fragments were separated 
from each other by a space not less than two inches, but remained 
united together by a long thick fibrous band. This was, of 
course, independent of the melanotic deposits, but the question 
might have been asked, with propriety, had not that fracture some¬ 
thing to do with the suppurative collection of the guttural 
pouches.
