of being beneficially applied to the ulcer. It will, at least, tho¬ 
roughly cleanse the part. By means of the nose-bag and the 
warm mash the chloride of lime may be introduced into the 
cavity, not only combining with the extricated gases, and re¬ 
moving the fcetor, but arresting the tendency to decomposition. 
Then there is a digestive—a gentle stimulus to abraded and 
ulcerated surfaces, rousing them to healthy action, and without 
too much irritating them—turpentine. We may apply this in 
the form of vapour, and in the best of all ways, by using the 
fresh yellow deal shavings instead of bran. This digestive may 
be brought into contact with every part of the Schneiderian 
membrane, and has been serviceable. 
The ulcer, however, may not be in the cavity of the nose, or 
if it be there, it may bid defiance to a stimulus so gentle as this, 
and a more powerful one we should hardly dare to use. Then 
we have another resource, and one that bids fairer to be success¬ 
ful than any other with which we are acquainted. The spring 
grass;—it is the finest alterative, depurative, and restorative in 
our whole materia medica; and if a salt-marsh should be at 
hand, we have still better hopes. The horse to which I just now 
referred was turned into a salt-marsh for five or six months; he 
came up with only a faint smell remaining, and that is gradually 
disappearing : but then I turned out another horse in the pre¬ 
ceding spring, and as nearly as possible in the same state, and 
he became glandered, and died. 
After all, our chief dependence must be on a power superior to 
that of medicine, and to which alone the occasional cure of ozena 
is to be attributed,—the vis medicatrix natures. ** The ulceration 
proceeds to a certain point—its progress is then arrested—the 
discharge gradually lessens—it loses its offensive character, and 
at length ceases.” We may in a slight degree assist and hasten 
the process, and that we should endeavour to do.

These parasites have been found in the nasal cavity of the horse, 
or the sinuses connected with it. A mare had chronic nasal 
gleet, accompanied by frequent and distressing cough. Bleeding 
and sedative medicines had been tried in vain. The groom had 
heard strange stories of worms and the larvse of certain insects 
finding their way into the nose and the cells connected with it. 
I ridiculed the idea; but on the same evening he blew a small 
quantity of pepper up the nostril of the horse, and in his violent 
sneezing, two small worms were discharged. I did not see them, 
and I have only the word of the groom for the fact, who with 
great triumph told me of the circumstance on the following
