THE TURBINATED BONES IN QUADRUPEDS. 275 
deceived the unwary, and been mistaken for a morbid tumour, or 
small polypus. Its use is probably to give some support to this 
part of the false nostril ; but it can have nothing to do with the 
sense of smell. 
The Protection of these Bones . — I cannot pass on without di- 
recting your attention to this. These delicate conchs lie principally 
under the nasal bone. I am sure that you have often admired the 
intricate, morticed connexion of these bones with the frontal ones 
above, and the firmness of attachment that is given to them, and 
which no human ingenuity could have better contrived — the 
denticulated edge by which the nasals are attached to each other, 
so far as the ethmoid bone extends, and some way along the tur- 
binators — the connexion of these bones with the superior maxil- 
lary bones below — the singularly and admirably contrived buttress 
— the two laminae of the maxillary, with the nasal bones deeply 
received between them — the squamous suture of the temporal bone — 
lowest of all, the processes of the anterior maxillary succeeding 
to those of the superior, and, between plates of these bones, many 
times thicker than the superior ones, the nasals being received, 
and placed almost beyond the reach of injury. These are elucida- 
tions of admirable contrivance that should not be lost sight of ; and 
much do I exult that the present demonstrator at the College rarely 
overlooks illustrations of this kind, so pleasing and so useful. 
There is a singular account of a horse coming within the reach 
of the sail of a windmill that was working very quickly. The 
blow fell on the side of the face, and, with such force, that it took 
away the whole of the nasal hopes, leaving the nasal cavity com- 
pletely exposed. The wound in a manner healed ; and the animal 
was able to work again, and continued at work, the part being 
merely covered by a piece of leather. There was not only no 
glanders, but his health was not in the least impaired. This, how- 
ever, was an exception to a general rule ; for the result is always 
to be feared when injury is done to the Schneiderian membrane. 
It is much to be regretted that no mention was made of the impair- 
ment, whether partial or total, of the sense of smell. 
Excision of the superior Turbinated Bone . — There is a case of 
this, and of considerable interest, upon record. An osseous tumour 
filled up the entire cavity of the left nostril, and, pressing the 
septum out of its proper situation, considerably encroached on the 
right nostril. Mr. Boycott, to whom we are indebted for this case, 
considered it to be a morbid growth of the superior turbinated 
bone, and advised the attempted excision of the tumour. Having 
cast the horse, he made an incision four inches in length along the 
edge of the nasal bone. He then made a second incision in a 
transverse direction from the superior extremity of the former;
