being necessary the horse was sent home. A letter from the 
Doctor since then says that the horse is much improved in his 
driving, has ceased shying, and that there is no discharge from 
his eye. 
The tumor was sent to Dr. Welch, of Bellevue Medical Col¬ 
lege, for microscopical examination, and he reports as follows : 
The epithelium is in most places preserved over the surface of 
the tumor. In the region where the specimen is of greatest thick¬ 
ness, there is a great hypertrophy of the epithelial covering, this 
being eight or ten times the normal thickness. In no places can 
alveoli or spaces filled with epithelical cells he discovered, as in 
true epitheliomata. The new production of epithelium appears 
to be wholly a surface growth. The tissue beneath the epithe¬ 
lium is everywhere densely infiltrated, with small round cells, 
betweeu which here and there can he seen racemose glands, partly 
hypertrophied. The lymph-follicles of the conjunctiva are numer¬ 
ous and swollen. The essential charges are, therefore: 
1. Hypertrophy of the epithelium covering the mucous mem¬ 
brane. 
2. Diffuse infiltration of the stroma of the mucous membrane 
with small, round or lymphoid cells. 
3. Hyper plasia of the lymph-follicles of the conjunctiva. 
4. A moderate hypertrophy of the mucous glands of the con¬ 
junctiva. 
The morbid changes resemble those met with in lupus of the 
conjunctiva.

We read in old works, and frequently in veterinary inquiries, 
in our agricultural and sporting press, of the protrusion of the 
haw or of the removal of the haw by being torn out, and the 
question naturally arises in our minds, are not such cases very 
likely to be due to the same cause, or be the same as that just re¬ 
ported, and in which the unskillful practitioner has by his tearing 
it out performed the operation of amputation, the only true 
remedy for the trouble.
