TUMORS.

1. 331
GRANULATION Mule with granulating" sores" on ri0 region and on breast. In curetting away. the exuberant growths a slight grittiness was perceptible, indicating calcareous degenera- . tion; this made the growths more consistent and more definitely granular. Another peculiar characteristic was observed; this hard granular growth extended quite a distance under the skin, and could be easiLy removed by pushing the curette up under the skin. After removing as much of the granular growths as possible with the curette, strong carbolic acid was applied and the following was prescribed: Oarbolic acid, 2 drachms; Iodoform, 1 drachm; Tannic acid, 1 ounce; Glycerine, I! pints. Mix. Apply daily after washing. In 4 or 5 weeks the wounds had all healed and there were no more signs of their return that year. But the next spring" the same kind of sores broke out all over the body and got so bad that I took the mule off and killed him" (owner). 2. Bay mule, 6 years old, with exuberant granulations on inside of left hind pastern. Out it off even with the surface, applied pulverized copper sulphate and then a bandage. As soon as the bandage was removed the mule was worked; the opposite foot struck the raw surface and the mule habitually gnawed it. Oonsequently, new growths were removed from this place eight times during the next two years. At present (J une, 18~6) a new growth as large, or larger than, any that were removed from the same place is now to be found; also, another tumor of the same nature has appeared, and has been removed 3 or 4 times, on the inner surface of the upper end of the canon region of the same leg. Microscopical sections of these tumors show that they are made up largely of embryonal cells not unlike the spindle cells of a sarcoma. In one sense this tumor might be called a malignant, spindle-celled sarcoma. However, it is best to regard it as res.ulting and recurring from mechanical irritation, and most probably extending from the same cause. It is well
to add that the mule was kept quiet only a short time dur-
332
ing these attempts at treatment and -much of the time he was at work in the plow or wagon. 3. Mule, 12 years old, with a very large granulation tu.mor on inside of left hock. Caused by sticking a knife into a varicosed vein (blood spavin) and injurious applications. Sliced away. the greater part of the granulations; applied pulverized copper sulphate and bandaged for two weeks; prescribed (a). Good recovery in 6 or 8 weeks. 4. Spanish Jack, 4 years old, with large granulation tumors on each limb. On one hind limb the growth covAred the entire outside and part of the front surface of the fetlock, the canon and the hock. The jack was greatly emaciated and had a very poor appetite. Applied pulver. ized copper sulphate and bandaged as directed on page 319. This jack was kept in t.he college hospital and the bandages were maintained in a fixed position by keeping the animal quiet and by close attention. In nine or ten the weeks bandages were left off and thereafter only creolin washes and carbolized oil and tannic acid were applied. In about six months these places had healed and the jack was in a greatly improved <IDndition. But from some unknown cause he was impotent; "he had no ambition." It is very probable that he was impotent when receivt0 for treatment. Recently, Dr. W. A. Heck of Keokuk, Iowa, has been very successful in treating gralll'liation tumors by cutting them down even with the surface and then giving intern.ltlly a teaspoonful of fluid <3xtrMt of ergot three times daily. The ergot tends to cut oj! the extra blood supply to the granulation tumor.-(C. A. C.)
PAPJ1.LOMAS (WARTS).
1. 'Gray colt, 2 years old, with extensive growth of "seed warts" (papillomas) on inside surface of both ears. Clipped them off with the scissors; curetted the surfaces, and applied corrosives f:!ublimate by rubbing large crystals over the raw surfaces. One week later, applied strong carbolic acid, and prescribed (c). These growths were so heavy that the ears were bent over. They nev5rreturned.

2. Colt, 1 year old, with warts on the internal surface of each ear; excised and cauterized with strong carbolic acid; never returned. 3. Filly, 3 years old, with papillomas on internal surface of each ear; curetted away the warts; applied strong carbolic acid; prescribed (c). Some of the warts were not entirely removed; hence, a second operation was required. 4. Bull calf, 2 years old, with papillomas on right thigh and groin; exci~ed; applied stro.ng carbolic acid; prescribed (0). Never returned. 5. Dog with papilloma on toe of front foot; excised; cauterized with strong carbolic acid; never returned. 6. Bay filly, 18 months old, with papillomas on internal surface...
