tonics (iron) are thus indicated. 
Chronic Abscess is comparatively slow in development, 
and is usually seen in old animals, and those of feeble or 
weak constitution. 
Such abscesses are generally large and deep- -seated, and 
considerable emaciation usually accompanies them. 
Treatment.— Evacuation by incision, as in the acute form, 
is, if practicable, decidedly advisable. Where, however, 
the situation renders opening dangerous, and the abscess is 
small, discussion should be attempted by the application 
of a stimulant to absorption over the part, and the ad- 
ministration of a similar agent internally. The tincture of 
iodine for the former, and the iodide of potassium for the 
latter, are the agents most frequently and beneficially 
used. 
Attention to the general condition of the system, 
especially to the secretions, is also necessary. The food 
should be plain, wholesome and nutritious. 
Internal Abscess can rarely be treated by surgical means. 
The symptoms are usually discovered, if in the lungs, by 
auscultation, nasal discharge, and the nature of the ex- 
pectoration ; if in the uterus, by the discharge of pus per 
vaginam ; if in the kidney, by heat and pain over the loins 
and difficulty in voiding urine, which is at times mingled 
with pus. 
The symptoms of hepatic abscess are extremely obscure 
—the usual indications of deranged liver are invariably 
present, and there is excessive pain on pressure to the 
right side, which the animal avoids lying on. 
TUMOURS. 
These may be divided into fatty, fibrous, calcareous, 
osseous, and melanotec. 
Fatty Tumours are of common occurrence in dogs, °
