nature the small-pox, measles, and scarlatina, to which the human 
subject is liable, and bearing some analogy to the cow-pox of 
cattle. 
The treatment of the disease is easy. What is chiefly requi- 
site is attention to the general health ; and in the more severe 
cases topical applications to the parts affected. The nature of 
the applications must vary with the stage and severity of the 
disease, and with the structure and functions of the parts to which 
they are applied. 
The great aim of the preventive measures ought to be, to keep 
up the health and vigour of the animal body, to remove the pre- 
disposing causes of the disease, to mitigate the virulence of the 
contagion, and to preserve the sound stock intact. 
ABSTRACT OF AN ACCOUNT OF A CALCIFIED 
TESTICLE OF A RAM. 
Published by Mr. Joseph S. Gamgee, Medical Student in 
University College. 
The morbid specimen described on this occasion by Mr. 
Gamgee was laid before the members of the Veterinary Me- 
dical Association during the session 1849-50. The animal from 
which it was obtained had never been recognised as a bad stock- 
getter. Hydrothorax was the cause of death. 
The object weighed fourteen ounces and a half avoirdupois, 
and in shape and size it resembled the healthy testicle of a 
ram. Mr. Tufnell, of the Birkbeck Laboratory, subjected a 
portion of the earthy substance to qualitative analysis, and 
ascertained its principal constituents to be, phosphate of lime, 
combined with a small quantity of phosphate of magnesia, a 
little sulphate and probably carbonate of lime ; also some nitro- 
genized organic matter. 
The surface of the testicle was of a dirty white colour, and 
slightly rough ; it presented to the naked eye very small yel- 
lowish white, crescent-shaped objects, closely packed, and in 
certain points apparently agglutinated together by a calcareous 
amorphous deposit. After a careful examination no doubt could 
be entertained as to the nature of the little objects in question ; 
they were the seminiferous tubes, impregnated with a calcareous 
matter ; and this to such an extent, that the area of the tubes 
was obliterated. “So closely,” the author remarks, “does the 
appearance resemble the characteristic structure of the testicle,
