PROGRESS OF VETERINARY SCIENCE AND ART. 573 
horses, I have seen during the summer months an immense 
number of little tumours develop themselves all over the 
surface of the body. They had the appearance of varicose 
cutaneous veins; the summit of the tumour ulcerates, and 
blood trickles out ; the hemorrhage affects so many points at 
once, that the animals are not in a fit state to leave the stable, 
as they are covered with little prominent ulcers, surrounded 
by fresh or dried blood, and the aspect is anything but agree- 
able. This is associated with intolerable itching, under 
certain circumstances ; and the only course of treatment, 
which perhaps may be dispensed with, is an aloetic purge. 
This disease may have some relation to the bud or boil of 
Biskra ; but so far as I can remember, for it is several years 
since I last saw it, no suppuration ensues, and the wounds 
heal rapidly. 
Shoulder Lameness. — On the 9th November, 1854, 
M. Vilatte presented to the Central Society of Paris the 
humerus of a horse affected with shoulder lameness. The 
history of the case, to be brief, is, that in the month of May, 
1851, he saw an English horse, lame in the near fore-leg, 
with a slight tumefaction over the antero-inferior part of the 
shoulder. Two blisters then cured him, and he remained 
well for two years. In the month of April, 1 853, this horse 
was again taken lame, but no history of his lameness could 
be ascertained. Violent pain of the shoulder-joint existed, 
especially on drawing the limb upwards and forwards. Emol- 
lients, blisters, setons, the actual and the potential cauteries, 
all failed in affording relief. 
After a while a tumour formed just above the joint ; it was 
the size of a hen’s egg, contained fluid, and probably commu- 
nicated with the joint or bursae, as it disappeared on pressure; 
a short time after another made its appearance outside, and a 
little under the articulation. After the application of blisters, 
an abscess formed in the latter situation, which M. Vilatte 
opened, and let out a yellow viscid pus with a grumous 
deposit. On pressure, flocculi of lymph were forced out, and 
there was no more doubt that the joint, or tendinous theca, 
was the seat of important and deep lesions. The horse 
was put to grass, but he got worse, and great emaciation of 
the muscles of the shoulder ensued, especially of those 
covering the fossae of the scapula,* and he was consequently 
destroyed. The post-mortem revealed the following lesions of 
the humerus, viz.: «, an osseous tumour, with asperities in 
the inner part of the head ; the trochlea destroyed, the 
* This lesion which Mr. Barlow, of Edinburgh, considers as constituting 
a special disease called “ shoulder slip ” has often been observed by M. 
Vilatte, but never of itself to produce lameness.
