PARTIAL OSSIFICATION OF THE RIGHT AURICLE 
OF THE HEART, WITH FIBRINOUS DEPOSI- 
TIONS ON ITS SURFACE, AND LIKEWISE IN 
THE SUBSTANCE OF THE SPLEEN. 
By T. W. Gowing, M.R.C.V.S., London. 
I have forwarded for your inspection the heart and spleen 
of a horse that first came under my notice about twelve months 
ago. The patient was a gray horse, belonging to an exten- 
sive cab-proprietor, and, when originally seen by me, he was 
affected with an eruptive disease of the skin, in the form of 
elevations or tumours, more particularly along the back, 
the sides, near hind-leg, lower part of the neck, and the chest. 
The eruptions were irregular in size and shape ; some of them 
being four inches in diameter, while others were small and 
circumscribed, and flattened on their surfaces. They were not 
tender to the touch. The animal’s appetite was capricious, the 
pulse intermitting, and the visible mucous membranes of a 
yellow colour ; the horse was, however, in fair working con- 
dition. My opinion was that some derangement of the liver 
existed, associated with an impediment to the free circulation 
of the blood. I contented myself by ordering a course of 
alterative medicine, and directed that especial attention should 
be given to the selection of the food, which should be generous. 
The eruptions remained for some time, but ultimately they 
became absorbed, and in about six or eight weeks the horse’s 
health was so much improved that he appeared capable of 
fully performing his duties, being, however, a great favorite 
of the owner, he was only used in gentle work. 
After a lapse of three months, the animal was again brought 
to me, suffering from a similar attack, but in a milder form ; 
he was treated nearly in the same manner as before. The 
cutaneous eruptions again disappeared, but the horse from 
this time lost condition, although he was liberally fed with 
malt mashes, oats, and beans. No further medical measures 
were adopted, but the animal was well nursed by the 
owmer, and very seldom used, as he thought he might 
ultimately be restored to health. On the 1st of January, 
1856, however, he came again under my care, and was now 
in an extreme state of emaciation. The skin w as free from 
the tumours, but it had a very unhealthy appearance. The 
coat w T as staring, and the animal was truly in a very pitiable
