of worms, certain precautions in feeding should be observed. If 
a single dose of a drug is to be depended upon, food should be 
withheld until after the bowels have moved freely. If, however, 
the drug is to be continued three or four days, the diet should be 
simple and as limited as the condition of the animal will permit, 
and allowing as long an interval as possible between the feeding 
and th: administration of the medicine. 
A very valuable and safe remedy for Ascarides in very young 
or delicate small animals weighing one to three pounds is worm- 
seed oil. This should be given in doses of one to four drops. It 
is well to combine the remedy with a drop of oil of aniseseed or 
oil of peppermint, well mixed in a teaspoonful of cod liver oil or 
castor oil, or it may be given in a little warm milk. 
PREVENTION. 
As the Ascaris develops in the bowel directly from the ovum 
or embryo, taken in with food or water, without requiring an in- 
termediate host, every effort must be made to prevent its admis- 
sion by these channels. Fecal matter, charged as it may be with 
the parasites and their eggs, may find its way into the drinking 
water or feeding vessels, and infect healthy animals. 
While it is true that we do not know the precise mode of intro- 
duction of a great number of parasites, we are yet not altogether 
at the mercy of their invasion. For them, as for the others, their 
germs are certainly derived from without; and it is evident that 
our animals can be rendered absolutely safe from them, if we can 
ensure the rigorous cleanliness of their surroundings and various 
hygienic agencies. But it requires continual, fastidious and patient 
care, which is generally so often neglected, and only comes into 
notice when circumstances have demonstrated the manner and 
seriousness of ati invasion. 
I wish to express my thanks and acknowledge my indebtedness 
to Mr. George M. Beerbower for the several excellent drawings 
of parasites contained in this article.
