These are commonly met with in the ducts of the liver, but as I have dwelt upon concretions, in general, we will only require to add here a few additional symptoms in order to assist in the proper diagnosis of the disease. These stones may vary in size from a pin-head to a pigeon's egg. The colouring matter of the bile seems to be reabsorbed, it then circulates with the blood, giving to the tissues that peculiar unhealthy yellow tinge. The signs are at first very obscure, but general yellowness of the mucous membranes will be observed; the animal will be restless and uneasy, respiration quickened, with an anxious expression about the face; but the most unpleasant symptom arises when the gall-stones pass through the ducts and become fixed in other parts. The pain produced is very acute, but the true and violent intensity of the sufferings are never properly comprehended in the lower animals even by the most descriptive and sympathetic witness.

Treatment

There are other diseases of the liver, such as chronic enlargement, serous and fatty degeneration, and rupture, etc, of which little distinguishing difference is perceptible from the diseases already described, therefore we need not occupy space by a repetition of analogous symptoms and remedies.
