with serous fluid; and it sometimes happens during life, 
from inflammation being created in the substance of the 
tumour, that this cystic fluid becomes purulent, the sac 
ruptures, and degenerates into a common, unhealthy, sub- 
acute abscess. Excision is, even under the circumstances, 
still advisable ; for even if we get it healed, and the tumour 
still remains, absorption is out of the question. Fibro- 
cystic tumour is usually present in “capped elbows.” 
Removal by excision is simple, and is followed by no ill 
effects. When they occur in connection with the hocks it 
is more advisable to use outward applications. I have 
found iodine the best agent. 
Calcareous Tumour.—This description of tumour is most 
frequently found in the vicinity of glands. In the dog, © 
it is generally seen in connection with the fibrous tumour 
of the mammary gland. In long-existing cases, the latter 
is often entirely supplanted by the former. 
Treatment.—As in the two former, excision is the only 
tissue, intermixed with a few fibres of yellow elastic tissue. Besides . 
the cyst which Mr. Gowing punctured, there was another of equal size 
which contained about four ounces of fluid, having the appearance of 
pus slightly tinged with blood. This fluid, under the microscope, was 
found to contain a large quantity of cholesterine, with exudation— 
corpuscles and blood-discs. In the interior of the cyst which was last 
opened, there was a small detached tumour of the size of a chestnut, 
smooth on the surface, and quite firm in texture. To the interior ot 
the walls of the two cysts were attached small tumours, varying in 
size from a pea to a hazel-nut, and on the surface of the lining of the 
cysts a quantity of flocculent white matter was deposited.” 
Three accompanying microscopic illustrations are given, to convey 
an idea of the structure of the morbid growths, which were all com- 
posed of the same elements. It is further observed: “It is obvious 
that the morbid growth originated in disease of the structures of the 
true skin, probably the result of an injury.” 
I recently removed a fibro-cystic tumour the size of a hazel-nut from 
a fore-toe of a small black-and-tan terrier. Placing a ligature round 
close io its attachment, I drew it sufficiently tight to sever it at once ; 
the hemorrhage, which was excessive for the situation, 1 stayed with 
cautery.
