That from the parotid gland, on the contrary, is thin and watery, easily penetrates substances taken into the mouth, and thereby favours their assimilation; while the saliva from the submaxillary gland is of a nature between these two.
The function of the submaxillary has much to do with taste; the fluid which it pours out dilutes and diminishes the pungent flavour of sapid substances, and at the same time weakens the energy of their contact.
Generally the attendant is alarmed by a snoring or wheezing noise emitted by the animal in respiration, before he is aware of the existence of any tumefaction. This continues to increase, embracing in its progress the adjacent cellular and muscular tissues, and frequently the submaxillary and parotid glands.
The disease, common in childhood, during which this gland becomes inflamed and swollen, is known as the "mumps." The submaxillary gland is placed below and to the inner side of the lower jaw, and the sublingual is on the floor of the mouth, between the tongue and the gums. Each gland opens into the mouth by a little duct. These glands somewhat resemble a bunch of grapes with a tube for a stalk.
"I need not note that the operation should be performed after the animal has fasted some hours. "As the success of the operation depends on an entire removal of the diseased parts, and as the submaxillary and parotid glands, with important branches of nerves and blood-vessels, are often enveloped therein, we must not hesitate to remove the former, nor to divide the latter.
There are three pairs of these: one just below the ears and behind the angles of the jaw, known as the parotid; one under the middle of the lower jaw known as the submaxillary; and a small pair just under the tip of the tongue, called the sublingual. These glands have grown up from the very simplest of beginnings.
The largest, called the parotid glands, lie, one on either side, in front of and below the ears. A duct from each gland passes forward along the cheek until it opens in the interior of the mouth, opposite the second molar tooth in the upper jaw. Next in size to the parotids are the submaxillary glands.
On account of its length it lies for the most part in coils, the two largest ones being known as the small intestine and the large intestine. Connected with the alimentary canal are the glands that supply the liquids for acting on the food. Mouth. 2. Soft palate. 3. Pharynx. 4. Parotid gland. 5. Sublingual gland. 6. Submaxillary gland. 7.

The submaxillary glands may be enlarged, and at first more or less hard and painful, but later they become nodular and adhere to the jaw or skin. Nodules and ulcers may form on the skin over the inferior wall of the abdomen and the inside of the hind limbs and are known as "farcy buds." Lymphatic vessels near these buds become swollen and hard.
After a debauch this patient experienced violent pain in the left cheek below the zygomatic arch; this soon extended under the chin, and the submaxillary glands enlarged and became painful; the face swelled and became erythematous, and the patient experienced nausea and slight chills.
