NASAL POLYPUS.

mile pretty well, but next morning she was down, and unable 
to rise, and a fracture of the off hind leg was plainly percep- 
tible. She was at once destroyed, when I found the os 
suffraginis of both hind legs fractured, but the divided por- 
tions of the near one were not in the least displaced, nor 
could the fracture be detected until all the surrounding 
parts were removed from the bone. The fracture in that of 
the off leg was both transverse and longitudinal ; the latter 
commencing in the centre of the articulations, both superior 
and inferior; and extending outwards, superiorly, and inwards, 
inferiorly, so that at the transverse fracture, which was at the 
lower third of the bone, they did not meet by a quarter of an 
inch. In the near leg the fracture was also transverse and 
longitudinal, the latter commencing superiorly, but extending 
to only two thirds of the bone where the transverse fracture 
existed. 
The opinion I formed was, that fracture without displace- 
ment had taken place at the time the lameness first showed 
itself.

SYMPTOMS OF POLYPUS IN NASO. 
These may be more or less severe, as in all other 
diseases. The size and situation of the tumour may be 
such as to endanger the animal’s life, the alarm being given 
by threatening suffocation. This is an important fact, so 
important that it may lead into error, and, as such, I wish 
to show that asphyxia may really depend on nasal obstruction, 
brought about very differently than by a fleshy mass growing 
within its cavity. As in man, there may be congestion of 
the mucous membrane, or deformity of either the bone or the 
septum nasi, hypertrophy of bone, or even osteoporosis and 
abscess in the sub-mucous areolar tissue, all of which will 
cause more or less difficulty in respiration. D’Arboval says, 
that in glandered horses epistaxis may occur, and blood-clots 
form and lead to an obstruction of the nasal cavities. I 
think there is not much fear that such an accident will 
happen, but as we are now discussing the chapter of acci-
