larly tlie inflamed cellular tissue, which is thickened, and which 
has become filamentous and hard and much impregnated with 
purulent seroBity. 
III.— Etiology .—Contusions of the region, bruises and punc¬ 
tured wounds are quite frequent causes of cutaneous quittor, but 
it may also take place without' evidence of determining causes. 
Mud, manure, urine, all filth in which animals have to walk or 
remain, are also considered as causes. For this reason the disease 
is more common in the fall and winter, on account of the action 
of cold at times, and frozen mud. It is also more frequent in cities 
than in the country. Kay observes that the mud of cities is al¬ 
ways more irritating and contains mineral substances, especially 
lime, alkalines and salts, and other substances. The gutters of 
some industrial establishments have also a direct irritating action. 
D’Arboval has observed that the mud of places where mineral 
springs exist is more irritating, as also are calcareous soils, where 
cutaneous quittor is more frequent than in any other. Common, 
large horses, notwithstanding their thick skins—or, rather on that 
account and on account of the hair which covers it—are more 
1 
commonly affected than private horses. Towing horses are much 
more exposed to the disease than those otherwise employed. 
IY.— Treatment .—As a first direction, during the course of 
the treatment it is always a prudent rule not to work the animal 
and to keep it in the stable, the feet being kept dry on a good 
bedding. An internal treatment is seldom necessary to control 
the general symptoms; if any is required, ordinary salines will 
generally be sufficient. It is necessary to assist the process of 
suppuration of the abscess by emollients, warm baths, poultices 
of flaxseed or of marshmallows, with melted lard, applied quite 
warm, or by the application of a mixture of honey and bran or 
flour. We have applied a coating of blister ointment to the tu¬ 
mor, covered with a warm poultice; the maturing effect is then 
very rapid. It is often necessary to lance the tumor to reduce 
the pain and prevent the mortification of a large piece of skin. 
This operation is recommended by D’Arboval and H. Boulev, 
and is specially indicated when the tumor is much developed. It 
is. then important to incise in the entire thickness of the dermis
