220 PROGRESS OP VETERINARY SCIENCE AND ART. 
The cow was in fair condition, gay, and fed well, furnish- 
ing about nine quarts of milk daily. 
The apparent absence of cancerous cachexia, only slight 
pain, led M. Saint-Cyr to think the tumour non-malignant. 
He resolved on operating, and began by incising the small 
tumour at the base of the ear ; then, with reference to the eye, 
he made a circular incision round the margin of the lids, 
dissecting back to the brim of the orbit, and continued 
his dissection, separating the ulcerated membrane from the 
degenerated osseous parietes of the orbit, penetrating deeply 
into this cavity, by passing the blade of the knife round the 
diseased mass. This was held out with a hook, and the 
whole carefully excised. There appears to have been much 
pain, but no bleeding ; tow, imbibed with alcohol, was care- 
fully put in the cavity, and the eyelids were brought together 
by three sutures to support the dressing. 
The globe of the eye was entirely disorganized, all its 
appendages, as well as its constituents, formed a homogeneous 
mass of reddish grey colour, adhering to the osseous parietes 
of the orbit. It was formed of a lardaceous tissue, more solid in 
the deeper parts, but ulcerated, irregular, of a livid red tint, 
and easily broken down towards the ventricle. 
After the extirpation, nothing particular occurred, the 
wound under the ear healed by the 5th of April, and by the 
8th, the cow was discharged from the infirmary with the 
orbit filled by granulations, and the lids cicatrizing from their 
canthi. 
Saint-Cyr’s principal object in publishing the above case is 
to show the success attending extirpation ; at the same time 
he has made some remarks on the nature of the growth, 
saying there have been three kinds of degenerations observed 
on the globe of the eye, the dermoid, melanotic, and fungoid, 
or sarcomatous. — Journ. Vet . de Lyon , May, 1855. 
M. Saint-Cyr asserts at the conclusion of his remarks on 
the above case, that he has not examined the specimen by the 
microscope, inasmuch as the natural and physical signs of 
cancer are always so marked and easily understood that there 
is never uncertainty as to diagnosis. We cannot pardon 
him, as he wishes us to do, for not having employed the 
microscope, thus leaving us in doubt as to the nature of 
the growth, for he cannot plead as his excuse that he had 
not an instrument at his command. He does not think 
the affection was cancerous ; so far as the history goes, there is 
every reason to believe the case was one of encephaloid. We 
do not contest that, in some instances, natural and physical 
signs are sufficient, especially after death, as in the case
