Report of the Governors of 
flammation, softening, and partial rupture ; in the uterus and its 
appendages by ovarian dropsy and vaginal tumours ; in the spleen 
and other organs by that remarkable and fatal affection, desig- 
nated splenic apoplexy, and also by cancerous deposits ; in the 
kidneys by calculi; in the tongue and the throat by scrofula; 
in the mammary glands by abscesses, as effects of the " foot and 
mouth disease," and in the feet by extensive ulceration, as another 
sequel to this disease. Besides these specimens of morbid 
anatomy some very remarkable illustrations of disease of the ribs 
of young lambs were supplied by a veterinary surgeon in Essex. 
In these cases large osseous tumours existed in different parts of 
the ribs, mostly, however, at the upper part or near the middle. 
Occasionally two tumours Avere present, although usually one 
only ; sometimes the ribs of both sides of the chest were affected. 
It was supposed at first that the enlargements had arisen 
from constitutional causes, and were probably the effect of 
scrofula ; a minute examination, however, completely disproved 
this idea, and showed that these tumours were produced by the 
reparative process, in excess, after fractures which had occurred 
in utero, probably through some injury received by the ewes. 
Some interesting cases of disease of the skin of lambs were 
likewise brought to the notice of the students. The disease pos- 
sessed all the characteristics of the affection known as crusta 
lactea in the human infant. 
The parts principally affected by morbid action were the face, 
eyelids, and ears. In some cases the sides of the neck, and even 
the shoulders of the animal, were ultimately attacked. Thick 
crusts of a dark colour covered the skin, which was also much 
inflamed and cracked. The young animals suffered much from 
local irritation and symptomatic fever, under which some of 
them sunk. The cases, however, were not numerous in the 
several flocks in which the disease appeared — not more than six 
or eight among 150 to 200 animals. Applications of the oxide 
of zinc ointment proved beneficial, but careful nursing and pro- 
tection, from both hot and wet weather, were needed as adjuncts 
to the treatment. 
Some other novel cases occurred in lambs, in which death 
resulted from parasites existing on the skin. The parasites in 
question Avere those commonly known as ticks (^Ixodes ricimus.) 
These epizoa abound in most countries, and are met with both 
on wild and domesticated animals, firmly attached to the skin, 
from which they draw blood as their food. Until now they have 
not been found on animals in Great Britain to an extent injurious 
to health, much less as a cause of death. In hot countries, how- 
ever, and particularly in many parts of South America, ticks
