Bourgelat relates a case in which a horse discharged a worm 
of the filaria species from his nose. He had been gradually 
wasting, and he continued to waste, and died. A post-mortem 
examination did not unfold any evident cause of death, but dis¬ 
covered other worms of the same species in the frontal sinus. 
CATTLE—FRACTURE. 
Cattle are not so much exposed to fracture of the nasal or 
superior maxillary bones as the horse is. The blows that are 
aimed at them, both by man and brute, generally fall compara¬ 
tively harmless on the broad expanse of the frontals above, 
which, from the strength of their curiously-constructed base, 
almost defy injury. The means pursued to reduce fracture would 
be the same, with the important advantage of not having the 
fear of glanders before our eyes. 
CORYZA IN CATTLE. 
Coryza is more frequent in cattle than in the horse, accompa¬ 
nied by the same mucous, purulent, foetid, excoriating discharge, 
but not so often running on to catarrh, bronchitis, pneumonia, 
and phthisis. 
Ca uses. —The prevailing causes are the same—overheated houses, 
or imprudent exposure to cold ; but the membrane of the nose is 
not so much irritated, or disposed to inflammation, by ammo- 
niacal gas, or other injurious effluvia. A cow-house may be as 
injudiciously close and heated as a stable, but its atmosphere 
will be of a very different character: no pungent vapour will 
there irritate the Schneiderian or conjunctival membranes, be¬ 
cause the urine of the ox does not contain the superabundant 
quantity of ammonia which is found in that of the horse, and 
held by so loose an affinity. There is, however, one unsuspected 
but too powerful occasional cause of irritation and inflammation 
of the Schneiderian membrane in cattle, namely, the dust and 
gravel of the road. The ox was not designed to be exposed like 
the horse to this annoyance. He has no false nostril to turn off 
the current of minute and irritating particles from the more sus¬ 
ceptible parts of the nasal cavity. Oxen driven any considerable 
distance to fair or market in dry and sultry weather, are sure to 
suffer, and sometimes materially, from coryza. Dairymen, whose 
cows have to travel half a mile or more morning and evening, 
along a dusty road, wonder that with all their care the beasts 
should be so subject to hooze. The cause is too palpable, al¬ 
though little suspected by them.
