slightly sore in traveling, but the lameness increases as the tumor 
enlarges in size. The region surrounding the tumor is always 
vaimer and more sensitive than is natural. In many horses the 
coronet presents a swelling, well marked. In some cases the dis¬ 
eased quarter is depressed, and the toe seems elongated. When 
a toe or quarter crack is accompanied with severe lameness kera- 
phyllocele may generally be suspected. But when none of these 
external signs exist it is exceedingly difficult to make a positive 
diagnosis of their presence: for though the swelling of the coro¬ 
net, the heat and the pain of the hoof may be present, those 
symptoms may belong also to other diseases of the foot. Then 
the only means at our disposal is to pare the foot well down, when, 
at the surface of the sole, the extremity of a portion of hoof or¬ 
dinarily harder than the normal consistency may be detected. 
I he treatment consists in removing the portion of the hoof 
corresponding to the horny tumor, as in a case of cracks, and 
treating the wound thus made in the same manner, according to 
the indications presented.

(REPORT TO THE COLONIAL SECRETARY.) 
To the Honorable the Colonial Secretary: 
Sir.—I have the honor to forward for the information of his

thrax or charbon—with which I am at present acquainted in 
this colony, showing the causes of this affection, and givin°- an 
outline of the treatment and the means of prevention which are 
calculated to be of most value. 
Anthrax is one of the oldest diseases known, as well as one of 
the most virulent. It derives its name from the formation of a 
pustule or carbuncle in certain cases and under certain conditions. 
In most cases in this country no pustule is developed, but other 
lesions characteristic of the disease are, by which it is easily iden-
