ointment, or with sulphuret of potassium 4 ounces, water 1 gallon, or 
with tar water, or the skin may be sponged with benzine. The appli- 
cation should be repeated a week later to destroy all lice hatched 
from the nits in the interval. Buildings, clothes, etc., should be 
treated as for fleas. 
STINGS OF BEES, WASPS, AND HORNETS. 
These are much more irritating than the bites of flies, partly 
because the barbed sting is left in the wound and partly because 
of the quantity and quality of the venom. When a swarm attacks 
an animal the result may prove fatal. 
Treatmené consists in the application of wet clay, or of a lotion of 
soda or ammonia, or of carbolic acid, or permanganate of potash, 
2 grains to the ounce; or of sugar of lead 2 drams, laudanum 1 ounce, 
and water 1 pint. The embedded stings should be extracted with 
fine forceps or even with the finger nails. 
TARANTULA AND SCORPION. 
The bite of the first and the sting of the second are poisonous, and 
may be treated like other insect venom, by carbolated glycerin, or a 
strong solution of ammonia, or permanganate of potash. 
SNAKE BITES. 
These are marked by the double incision caused by the two fangs, 
by the excessive doughy (dark red) swelling around the wounds, and 
, in' bad cases by the general symptoms of giddiness, weakness, and 
prostration. They are best treated by enormous doses of alcohol, 
whisky, or brandy, or by aqua ammonia very largely diluted in water, 
the object being to sustain life until the poison shall have spent its 
power. As local treatment, if the wound is in a limb, the latter may 
have a handkerchief or cord tied around it above the injury and 
drawn tight by a stick twisted into it. In this way absorption may be 
checked until the poison can be destroyed by the application of a hot 
iron or a piece of nitrate of silver or other caustic. A poultice of 
tobacco leaves is a favorite remedy, and may be used to soothe the 
sore after cauterization. 
A treatment which has been highly recommended consists in 
prompt and vigorous scarification at the site of puncture and rubbing 
erystals of potassium permanganate into the wound.
