ON TUMOURS IN CATTLE.

what I have alluded to. Mr. Hood states, that his cattle were kept in 
a well sheltered straw-yard from October to May ; but that they were 
put to the fields for several hours a-day. Now, it is probable that 
from the circumstance of the straw-yard being comfortable, the 
cattle would be thereby rendered more susceptible of injury when 
turned out from it to the cold and exposed fields in which they re- 
ceive their turnips. That the disease arose from atmospherical 
causes seems also evident from the circumstance of a malady very 
analagous having prevailed this summer amongst horses in several 
parts of the country, in which the lymphatic glands of the throat 
seemed to be the parts most conspicuously affected ; and this dis- 
ease has undoubtedly arisen from the state of the atmosphere. 
The disease, when it occurs in the southern parts of Scotland, is 
commonly known by the term Clyers in the throat , and seems to 
be very analogous to strangles in horses. The treatment, however, 
is somewhat more difficult in cattle than in horses, and its effect 
more fatal; for, as I have already stated, there seems to be a weak 
or depressed state of the system connected with it, and the disease, 
from this cause, instead of proceeding to suppuration, and forming 
an abscess, which bursts and discharges itself freely, as in horses, 
often assumes an indolent state, and discharges but a little from 
different points, and afterwards forms sinuses ; or the matter is 
partially absorbed, and a tumour is formed. I have been informed 
by eminent farmers, that cattle bred in-and-in are very subject to 
clyers in the throat, after they have attained their first year. 
These clyers affect their breathing at all times, but do not prevent 
their feeding till the act of deglutition is rendered painful by the en- 
largement of the tumour. Young queys are most susceptible of 
this disease, which, of course, renders them unfit to be kept for 
breeding. This fact still corroborates my view of the disease ; for 
it is a well-known circumstance, that breeding cattle in-and-in ren- 
ders their constitution very delicate ; and were the facts correctly 
ascertained previous to the symptoms of that disease appearing, I 
have no doubt they would be found to have arisen from injurious 
exposure to the weather. 
From this view of the disease, it becomes necessary to attempt 
the cure by confining the animal in a comfortable byre or shade, 
and increasing the strength of the system by a nutritious diet, 
combined with tonic medicines, such as the sulphate of iron, in 
doses of !2 drachms to a middle-sized two or three year old, once a 
day, in a little gruel, or five grains of iodine in gruel night and 
morning. The tumour should be laid open if matter is to be felt ; 
but if not, a blister should be well rubbed into the surface of the 
swelling, and repeated until there is either absorption of the tumour 
or the formation of an abscess. Should this plan not answer, in
