should be made into ten tablets or pills, one of which may be given every hour. 
If, however, he is of smaller size, the number of tablets or pills should be in- 
creased to twenty, and one be given every hour. 
In pups only two or three weeks old the nasal trouble interferes with the nurs- 
ing and prevents sleep, yet but little can be safely done for them. Some relief 
may be afforded by lubricating their nostrils with vaselin, fresh lard, or the like. 
If danger seems to be threatened, a soothing inhalation should be tried as follows: 
Place the pups on a chair having a cane seat, and raise over it an umbrella, al- 
lowing the same to fall as low as possible. Into a pint of boiling water put two 
teaspoonfuls of the compound tincture of benzoin. Let this be in a shallow pan 
under the chair. In order to generate a vapor, heat stones about half the size of 
the fist, and put one into the pan. Follow this with others as often as necessary, 
for fifteen or twenty minutes. 
In cases caused by the parasite described, and the patient an old pup or ma- 
ture dog, it is advisable to first open well the nasal passages by means of a five 
per cent solution of cocaine. A little of this can be thrown in by a spray-pro- 
ducer, or introduced on a small bit of cotton securely fastened to the end of a 
large strong straw taken from a broom. ‘Then the passages should be syringed 
with the peroxide of hydrogen diluted with three parts of water. Thus the para- 
site should be at once destroyed. It sometimes, however, as stated, penetrates 
to the cavities of the forehead, where it is possible to reach it only after the 
operation of trephining has been performed. 
LARYNGITIS. 
The larynx is the vocal part of the windpipe, located in the throat at the base 
of the tongue, and an inflammation of the mucous membrane which lines it is 
termed laryngitis. In general character it closely resembles the same affection 
in man, and may run a course so mild that it be insignificant; or the inflammation 
may be intense and excite other changes, which render it very serious, and even 
a menace to life. It may also be acute or chronic ; but the latter is very uncom- 
mon, consequently the former only deserves to be considered at any length. 
Acute laryngitis may be caused by exposure to sudden and great changes in 
temperature, and this is the rule in man; but in dogs the common causes are me- 
chanical injuries, as from slivers of bone lodged in the throat, irritant inhalations, 
or prolonged barking. Indeed, it is very often induced by the latter during dog 
shows. External injuries to the neck may also excite it, as tugging at the chain; 
and pugs and other small pet dogs which their owners exercise under restraint 
are frequent victims. In these instances, fortunately, the affection is usually 
of short duration. Of the various irritants, smoke is the most active one likely to
