below the arch and kept until the urethra was entered, without 
the animal exhibiting the slightest pain. A pair of dog obstetric 
forceps being introduced into the bladder, the noise that it made 
in coming in contact with the stone rendered the diagnosis posi¬ 
tive. An assistant then introduced his hand into the rectum, 
and, grasping the calculus, pushed it back between the jaws of 
the forceps, where, it being firmly held, it was with much trac¬ 
tion removed, the animal showing scarcely any pain as the large 
body was extracted. The calculus, when fresh, weighed over six 
ounces, and measured inches on its small and 6 inches on its 
larger circumference. Its external surface was somewhat rough, 
and its structure analagous to those of a similar nature. The 
animal was discharged convalescent in a few days, the wound 
being left alone and cleanliness being the only after cares of the 
operation. 
EMBOLISM OF THE ILIAC OF BOTH SIDES. 
By H. B. Ambler, Student. 
Through the kindness of Dr. G. Bridges, this patient was sent 
to the hospital for the benefit of the students and for post mortem 
examination. 
Admitted on the 18th of March. The animal was a roan 
mare, about nineteen years old, which for the last six months had 
shown peculiar lameness. Whenever driven for about half a 
mile she would get lame, perspire profusely, her respiration be¬ 
came hurried, her pulse very weak, and then she would lie down 
in great pain. She had been treated for colics and for azoturia, 
but as she would recover from these attacks so quickly—viz., as 
soon as she had thoroughly cooled off—these diagnoses were con. 
sidered as incorrect. 
As the history of her case led to suspicion of embolism of the 
iliac arteries, a rectal examination was made when she was cold, 
and a weak pulsation detected on both sides. She showed cramps, 
however, on the right side. 
On the 24th of March she was taken out of the stable and 
exercised. She had gone but a short distance when the cramps
