ON SOME LATE EPIDEMIC DISEASES. 485 
marked in its effects upon tlie bodies of animals, especially in 
the northern metropolis, and surrounding country. First, in pro¬ 
ducing the fatal and destructive bronchitis which so generally 
prevailed; next, in derangements of the bowels analogous to 
cholera ; and lastly, in three other forms of disease :—First, sore 
throat, terminating in strangles, in which the disease appeared 
in varied forms, the abcesses being found in all parts of the body, 
and, in some, proving fatal by the tumours interfering with the 
functions of organs essential to life (the lungs and abdominal 
viscera); and, in others, proving destructive, by the abcesses 
bursting into the chest or abdomen, and setting up a destructive 
irritation. 
Secondly, Erythematous disease, in which sudden eruptions 
have taken place generally over the whole body, attended with 
low febrile action, weakness, and slight soreness of the throat, 
but, otherwise, with little disturbance of the respiratory organs ; 
slight derangement of the abdominal viscera, but no apparent 
derangement of the sensorium: the eruptions on the skin, in 
some cases, disappearing as suddenly as they came, but general¬ 
ly returning a few times before they entirely left the animal; in 
other cases proceeding at once to a slight effusion from the sur¬ 
face of the tumours, followed by a desquamation of hair, and then 
going quite off; while, in others, a permanent alteration of the 
skin has followed, by a deposit of a small quantity of calcareous- 
like matter in it, forming little tumours. The animal during the 
disease shewed considerable weakness, attended with loss of 
flesh and condition; being unable to stand free blood-letting, 
and, from the absence of the buffy coat on the blood in the early 
stage of the disease, apparently not requiring it; therefore mild 
purgatives, with diaphoretics, producing the most speedy return 
to health. 
Thirdly, The frequent occurrence of tetanus, of which we have 
seen six cases within the last four months, and have heard of 
many others. Four of those which we saw occurred in April, 
and two in July. Those in April arose from the effects of cold, 
being attended with symptoms of an affection of the pleura, and 
which was proved by the post-mortem examination of one of
