ADENITIS, 377 
lungs), bring on excessive emaciation and end in death. It is not glanders, 
nor tuberculosis, but a special microbian affection. In the post-mortem 
pieces sent to Nocard by Couzin, he found a “ fine and long bacillus, 
assuming the form of little snakes entangled together; the central part 
resembling an opaque nucleus, from which radiated towards the periphery 
delicate ramified threads ; it gives the idea of the head of a cauliflower, a 
bundle of thorns, or, better, a seed of burdock.” It is inoculable to the 
guinea-pig, cow and sheep. Horse, donkey, dog, rabbit, are refractory. 
On these animals it only gives rise to a small abscess at the point of 
inoculation, 
Puncture of the abscess, made at an early date, free incision of the 
cord, cauterization, curetting of their internal surface, constitute the local 
treatment. Good food, tonics, stimulants, are also indicated. Recovery 
occurs generally; but one must count with the inflammation of the sur- 
rounding lymphatic vessels and glands, and many subjects die in marasm. 
Tuberculous lymphangitis have been studied but little in animals. 
Godbille records an interesting observation of it. A steer in good con- 
dition had on “the external face of the right anterior leg, a linear series of 
bosselated, irregular tumors, of the size of the fist and moving under the 
skin.” The lower one was ulcerated, others showed fluctuation. On post- 
mortem, all the internal organs were healthy, except some mesenteric 
glands, infiltrated with granulations. Recognized early in some species, 
tubercular lymphangitis may be treated either by incision and curetting, 
or by excision ; in some cases, the extirpation of the collecting ganglion 
completes the interference. (See Zuberculosis.) Cancerous lymphangitis, 
common in dogs, are most always present in cases of serious epithelial 
tumors. Very frequent in the mamme of sluts, they constitute thick 
subcutaneous cords, nodular, and extending to the glands. Their total 
extirpation, when the disease is comparatively recent and the patient 
strong, is the only proper treatment. Old age, anemia, generalization of 
the neoplasms, counter-indicate interference. (See Zumors.) 
Lymphangitis of distemper are ordinarily not serious. In general, ab- 
scesses punctured and freely opened recover by the simplest antiseptic 
cares and the lymphatic induration diminishes little by little.

ADENITIS. 
True filters placed on the course of lymphatics, the glands arrest in- 
fiectious germs carried by the lymph. Their pullulation, the increasing 
irritation that they produce on the glandular stricture, promote adenitis.
