HISTORY, & C. OF AN OSSIFYING ENCHONDROMA. 695 
Fowls are also said to have become affected by this epizootic. 
It has occasionally been communicated to the human subject, 
generally by milking, with abraded hands, by cows affected with 
the disease. Febrile symptoms soon develop themselves, and the 
hands and mouth become covered with a vesicular eruption. The 
cases, however, do not seem in general to have been severe, and 
the persons rapidly recovered.

Abstract of a Pamphlet published by Mr. Joseph S. Gamgee, 
Student in Medicine in University College , on the “ History 
and Description of an Ossifying Enchondroma con- 
nected with the Testicle of a Horse.” 
The diseased specimen which formed the subject of the paper 
was removed from a four-year-old horse in the operation of castra- 
tion, by Mr. Cook, veterinary surgeon at Erith. The animal 
was the sire of several colts, and, though he had been always in an 
emaciated condition, yet did not appear to suffer any particular 
inconvenience from the presence of the diseased testicle, which 
was found, on removal, to contain nearly an ounce of dirty-looking 
serous fluid. The gland nowhere presented its normal structure, 
though the spermatic vessels and vas deferens exhibited no signs 
of disease, either to the naked eye or by the aid of the microscope. 
The tissue of the testicle was soft and flabby, of a red colour, and 
ill defined structure ; from before backwards it gradually became 
less in amount, of a pale colour, and eventually degenerated into a 
thin layer of white fibrous tissue, which was intimately connected 
with a tumour of moderate hardness, about the size of an orange. 
The interior of the diseased mass having been exposd by a longi- 
tudinal incision, it was found to be of a pale yellow colour, finely 
and irregularly lobulated, and to contain three small cysts with 
fluid albuminous contents. The physical appearance of the cut 
surface neither resembled that of genuine adipose nor fibrous tissue; 
but what would, a priori , have been anticipated from an intersec- 
tion of a mass of fat by bundles of fibres. In the centre of the 
exposed surface, some cartilage was visible, and this could be seen 
and felt extending into the substance of the tumour, which at one
