thought was probably an exfoliating piece of the temporal bone ; but 
on second thought, it occurred to me that, possibly, it might prove to be 
one of those interesting dental tumors which I had seen recorded, but 
had never met with. An operation was decided on. A crucial inci¬ 
sion was made over the tumor, and at the depth of about an inch 
the black crown was exposed pointing upwards; and after exerting 
pressure on the sides of the tumor in different directions with a chisel 
it was extracted with the forceps. A little tr. of iodine was occasionally 
injected into the cyst in which it was lodged, and in about two weeks 
the part was quite healed. The tumor proved to be Composed of tooth 
substance, and in shape very much like a molar, was about twothirds 
the size of an ordinary molar tooth with imperfectly developed fangs, 
and was firmly attached to the temporal bone and surrounding struc¬ 
tures. I am, etc.,

VESCICAL CALCULI—CYSTITIS—DEATH. 
• Springfield, July 17th, 1877. 
My dear Doctor : 
I send you by express to-day the penis and bladder of a dog which 
recently died under my care ; he was owned by a Mr. J. Hunter, of your 
city, and it is possible that he may call upon you to see it. I saw him 
first at about 10 o clock on the night of the 12th inst.; penis was swollen 
as you see it, and of a deep, mulberry color, dribbling of bloody urine; 
examination showed a calculus lodged just at the back of the meatus in 
the urethra (you will see the spot) : this I crushed and removed next 
morning, the urine continuing in drops and bloody; I passed catheter 
(passage was free) into the bladder, and no calculi could be sounded ; 
three or four ounces of effusive bloody urine were evacuated through 
the catheter, the bladder washed out with tepid water, and a solution 
of carbolic acid, 1 part to 200 parts of water, all being thoroughly evac¬ 
uated by manipulation ; symptoms still continued, with increased fever. 
At about 4 p. m., temperature, 103£ F.: pulse, 184; breathing, quick. 
About 5 o’clock, bladder again washed out, sounded, etc., with appa¬ 
rent relief. He died at about ten in the evening. On the 14th, post¬ 
mortem, Sunday morning ; results as you will see. He died of pyemia, 
the piostate being full of pus, as well as the whole parts being more or
