CHRONIC DIARRHCEA IN NEAT CATTLE. 
with grey semi-transparent tubercles, varying in magnitude from 
a large marble or walnut to a pea. Altogether, the morbid 
growths were of a rare and interesting character; though they 
were become too far changed by decomposition to admit of any 
very accurate or minute description of them.—E d. Vet. 
CHRONIC DIARRHCEA IN NEAT CATTLE. 
By Mr. Geo. Lewis. 
THERE are various causes productive of chronic diarrhoea, as 
there are also of acute ; and although the first sometimes has the 
latter for its cause, the effects are different in each disease, as 
are the causes producing them. For instance, that which would 
be productive of acute diarrhoea in a sound animal, would not 
materially affect one suffering from chronic diarrhoea. 
That they are two distinct diseases may be adduced from the 
fact, that an animal suffering from an attack of the acute disease 
is quickly and successfully treated by remedies which would 
have no effect upon one suffering from the disease in a chronic 
form. 
There are different kinds of this disease ; of which one is in¬ 
termittent, and is believed by many country people to be 
influenced by the moon. This has its cause in a weakened 
state of the liver, and its consequent susceptibility of becoming 
easily and unduly excited by different agents; which, being 
removed, the animal, to use the words of the owner, “ soon gets 
well again.” 
Another kind is that to which yearlings are subject, when 
calves have not had proper food, or have been fed with broths 
with a view of saving the cow’s milk. This kind of chronic 
diarrhoea, if improperly treated, renders the career of the animal 
short; but, if submitted at once to proper treatment, and there 
be not considerable structural derangement of the liver, there is 
still a favourable prospect of recovery. 
To the other kind, of all the most subject to it, are cows 
which are “good milkers;” but why they are so I will not attempt 
to explain; unless it be, that there is a greater demand upon 
the system, and that they are more inadvertently exposed to the 
inclemencies of the weather, by being turned out of a protected 
fold or warm shed, after being milked, into a cold and unprotected 
field, where they become exposed to a cold, wet, or frosty at¬ 
mosphere, and are allowed to remain until again wanted for the
