REVIEW — CATTLE PATHOLOGY. 693 
A portion of the history of this will be quite new to some of our 
readers, and all will derive instruction from it. 
They are indolent tumours, gradually and slowly increasing, 
and which form cords or chaplets round the neck, behind the ears, 
and under the lower jaw. They are irregular, bossed, some hard 
and scirrhous, and others soft, and occasionally both varieties of 
structure are found in the same gland. Their adherence to the 
surrounding parts increases with their density, and which, occa- 
sionally, is almost that of marble. I have seen a large chaplet of 
these' scrofulous tumours under the jaw of a pig, and adhering as 
closely to it as if it were composed of bone, and resembling more 
an osseous concretion than a simple scrofulous tumour, and yet the 
animal became as fat as if nothing had been the matter with him. 
These tumours never suppurate unless they are wounded or injured,, 
and they never disappear on account of the characteristic inertia of 
their structure, until they become scirrhous, and then they degene- 
rate into cancer. 
They are hereditary, but they are principally caused by a hu- 
mid atmosphere, unwholesome food, want of exercise, and wet and 
ill- ventilated sties. They are not contagious ; they do not attack 
the teats. Unwholesome food is the principal cause, — the digestion 
is vitiated, and the chyle not well elaborated. 
They do not appear to suffer any inconvenience from this 
scrofulous affection. They eat, and drink, and grow, as usual; 
and the veterinary surgeon should not undertake the medical treat- 
ment of them unless it is forced upon him. Indeed, if the existence 
of the disease seems to have little connexion with condition, or the 
want of it, it would be folly to attempt difficult or painful opera- 
tions upon them, or to commence a course of medical treatment, 
which, besides some necessary expense, would lessen their condi- 
tion and value. The veterinary surgeon should always have for 
his object the interest of the proprietor, and he should never attempt 
the cure of these diseases, except the extraction of the tumour is 
easy, or the animal is young, or the tumour diminishes his value, 
as, perhaps, would be the case in oxen from four to six or seven 
years old, and in the country in which they are bred. 
If the proprietor will have a cure attempted, M. Toggia recom- 
mends the knife, followed by the iron at a white heat; and he cen- 
sures, and with reason, the employment of all caustic and arsenical 
compositions, for the disease is almost sure to reappear. After the 
removal of the tumours by the knife, he recommends mild but 
plentiful nourishment, as carrots, parsneps, beet-root, &c., and the 
occasional administration of the bitter tonics, as gentian. He has 
also seen benefit derived from the internal use of iodine. He con-
