weighing 1.5 pounds (ca. 700 grams), given by means of a hard rub¬ 
ber rectal syringe, infant’s size, has been found to remove 90 per 
cent of these worms. Double the dose for birds weighing three 
pounds or over. The tip of the syringe should be passed along the 
floor of the cloaca. 
For a mass treatment, the tobacco treatment given above for the 
large roundworm has been found, when given once and not repeated, 
to remove about one-fifth of these cecum worms. If repeated at in¬ 
tervals of a month this might serve as a control measure of some 
value. 
Spirurids. We have as yet no known effective treatment for the 
spirurid worms which occur more or less embedded in the tissues of 
the digestive tract of poultry. 
Tapeworms. No satisfactory treatment has yet been established 
for tapeworms in poultry. A mass treatment which has been recom¬ 
mended is as follows: A gallon of a mixture of wheat and oats, to 
which is added a small tablespoonful of concentrated lye, is cooked 
slowly for about two hours and allowed to cool. The birds are fasted 
for 15 hours and then given as much of the mixture as they will eat, 
with plenty of water. 
ADDENDUM 
Lamson has recently reported good results in removing stomach 
worms from sheep by means of a nicotine sulphate solution. Using a 
commercial preparation containing 40 per cent of this substance, he 
makes solutions of three strengths, adding one, two or three teaspoon- 
fuls to a quart of water. For weak sheep, use the weakest solution at 
the rate of 4 ounces to an adult and 2 ounces to a lamb. For average 
animals use the same doses of the stronger solution, and for strong 
animals the same does of the strongest solution. Fast for 12 hours 
before and 8 hours after treatment.
