276 COMPARATIVE ANATOMY" AND PATHOLOGY. 
and, on dissecting back the flap, a considerable portion of the side 
of the tumour projecting through the aperture between the nasal 
and superior maxillary bones, was exposed to view. With a 
chisel and mallet he removed about two-thirds of the tumour in 
one mass; and, afterwards, by means of the same instrument, 
cleared the cavity of every particle of morbid growth. The ope- 
ration was necessarily long, and attended with great loss of blood ; 
but the animal was quite well six weeks afterwards, and was con- 
stantly ridden as a hack, without any impediment in his breath- 
ing, or the least deformity remaining. The tumour was of a 
conical form, five inches in length and six in circumference. 
The internal structure was that of the turbinated bone, cancellated 
and spongy. This is an interesting case, and does Mr. Boycott 
much credit. Here also I wish that he had said something of the 
apparent impairment or otherwise of the sense of smell. So far, 
however, the operation is valuable, as shewing us that we may 
occasionally take great liberties with these bones. 
Instrument for excision of the Turbinated Bones . — A French 
practitioner, M. Germain, invented an instrument for the cure of 
glanders, by the removal of the turbinated bones; and a school was 
established, at immense expense, in which the mode of operation 
was taught. The editors of the French Journals, although too 
often and too seriously disagreeing with each other, united in ex- 
posing the folly of such an attempt. “ The membrane of the tur- 
binated bones,” they said, “ was not the only one that was exposed 
to ulceration, or secreted the infectious discharge. Although they 
were composed of numerous catties, the matter of glanders was 
not collected or accumulated in^hem, but in the sinuses which 
communicated with the nose. Such an operation, therefore, could 
not produce any good effect ; for the other portions of the cavity 
would continue to be diseased, and probably the inflammation 
would be aggravated by this dreadful operation.” I ought, per- 
haps, to apologize to you for saying one word respecting this folly : 
but you should be acquainted with every experiment, foolish or 
commendable, instituted in order to diminish or prevent the 
ravages of this disease. For awhile this excision of the turbi- 
nated bones was the rage in France, and more than a hundred and 
fifty thousand francs were expended by one of our countrymen, 
not five years ago, in this ridiculous business. 
The Ox . — In this animal the turbinated bones, like the ethmoid 
bone, are considerably more developed than in the horse, for the 
reason stated in my last lecture — that he has occasion for greater 
acuteness of smell, and particularly in the early part of the year, 
when the plants are young, and have not acquired their full scent. 
The loiver of these bones is very much larger that in the horse ;
