Hookworms. Carbon tetrachlorid as given above for ascarids. 
Efficacy, 93 per cent or higher. 
Whipworms. The treatment recommended in the case of the 
dog whipworm would probably be effective, using suitable doses, 
but unless treatment was very necessary the difficulties of giving 
repeated doses of santonin to foxes would not warrant it. 
Tapeworms. The treatments recommended in the case of dog 
tapeworms would probably be effective, using suitable doses. 
Flukes. Carbon tetrachlorid, as given above for ascarids, is re¬ 
ported by Jeffreys as 100 per cent effective in removing intestinal 
flukes from foxes. 
TREATMENTS FOR POULTRY PARASITES. 
Large roundworms (Ascaridia perspicillum) : A mass treatment 
recommended by Herms and Beach is as follows: For 100 birds, steep 
one pound of finely chopped tobacco stems for two hours in water 
enough to cover them. Mix the stems and the liquid with one-half 
the usual ration of ground feed. The day previous to treatment with¬ 
hold all feed, giving water only. After fasting 24 hours, feed the 
mash thus prepared, and two hours after it is cleaned up give one- 
fourth of the usual amount of ground feed mixed with water in 
which Epsom salt has been dissolved at the rate of 11 ounces for 
each 100 birds. The treatment should be repeated 10 days later. 
For a mass treatment where only a single treatment is given, use 
one teaspoonful (approximately one fluid dram or 3.75 cc.) of oil of 
chenopodium, thoroughly mixed with a moist mash, for each 12 birds. 
For individual treatments, oil of chenopodium, 0.2 cc., in castor oil, 
2 cc., has been found to remove 69 per cent of these worms;, turpen¬ 
tine, 2 cc., in castor oil, 8 cc., has been found to remove 76 per cent 
of these worms. 
Cecum worm (Heterakis papillosa) : Rectal injections of oil of 
chenopodium, 0.1 cc., in a bland oil (as cottonseed oil), 5 cc., to birds
