by numerous smaller ones of the same nature and aspect. The 
malignant nature of the disease was also more evident. Another 
operation was performed, with a less favorable prognosis and yet 
the animal was discharged two weeks later, cured. A few weeks 
later, however, the growth had returned, with numerous secondary 
tumors surrounding it, and now extending around the margin of 
the anus. From this time the animal grew worse and difficulties 
manifested themselves in the functions of the hind quarters; 
weakness of the hind legs, first betrayed by difficult locomotion, 
was followed by inability to rise from the ground unaided, and 
then came entire paraplegia, soon succeeded by constitutional dis¬ 
turbances ending a little later, in death. At the post-mortem, 
besides the lesions of the tail, a large tumor was found on the 
left side of the anus, and united with melanotic deposits situated 
under the sacrum. The liver, the spleen and the lungs were filled 
with growths of various sizes and the endocardium of the left 
ventricle of the heart was covered with melanotic spots, while a 
tumor of the size of a nut was also found in the rachidian canal, 
on a level with the third lumbar vertebrae, and pressing on the 
spinal cord. 
This case, according to the author, is interesting because of 
its being unique in the works of veterinary literature, and on ac¬ 
count of the light it throws upon the ultimate nature of melanosis.

TREATMENT OF WARTS, MELANOTIC TUMORS, FIBROMA, SAR¬ 
COMA AND OTHER GROWTHS, WITH ARSENIOUS ACID. 
By M. Lignon. 
For the last eight years the author has adhered to this treat¬ 
ment for the above named growths, and he claims that his efforts 
have been rewarded with uniform success. This treatment com¬ 
mends itself in every case in which the growths are developed 
on the skin or in the sub-cutaneous connective tissue, when not 
in proximity with important organs likely to involve complications 
which may bring on fatal results or blemishes of the animal 
affected. 
Indications .—When a heteromorphous tumor of whatever na¬
