COMPARATIVE HELMINTHOLOGY. 
\CISTICEECUS TENUICOLLIS IN AN ADDAX ANTELOPE AND A MOOSE. 
By tiie Same. 
About seven months ago an addax antelope was found dead 
at the menagerie of the Central Park. She had been sick for a 
few days with diarrhoea, loss of appetite, &c., but her disease 
had not been diagnosticated, and Mr. Conklin, the Superintendent, 
sent her to the American Veterinary College for post-mortem. 
A careful examination failed to demonstrate any cause of sickness 
except in the abdominal cavity. On the opening of this part of 
the body the great mesentery, which was spread over the whole 
intestinal mass, was found covered with a large number of little 
bladders, varying in size from that of a small pea to that of a 
lady’s apple—some pedunculated, others closely adherent to the 
peritoneum. They contained, visible to the naked eye, little 
white bodies adherent in many places to the walls of the cyst. In 
removing the omentum and exposing the intestines, these were 
found also covered with similar cysts—some collected several to¬ 
gether, others single, and a large number of these were found 
loose, floating in the peritoneal fluid. All the organs were found 
healthy except the liver, which presented on its surface a few 
cysts, imbedded in the thickness of the capsule of Glisson. A 
diagnosis was made accordingly. 
On the 28th of Aug. I received word from Mr. Conklin to call 
at the menagerie and look at a moose which had been sick for three 
or four days. Her appetite had been failing by degrees, she had 
lost considerably in flesh, and was suffering from severe diarrhma 
also. When I made my visit about an hour afterwards, I found 
the animal had died but a few minutes before. 
Our arrangements were made to have her at once brought to 
the American Veterinary College, where post-mortem was made 
immediately.
