RK oussin.—This is reported as giving good results in 2-grain doses. 
It expelled the tapeworms, and the animals remained in good spirits 
and improved in condition. 
Oleoresin of male fern.—This is given in doses of 1 dram and may 
be given with 2 to 4 ounces of castor oil. 
Areca nut—This may be given to lambs in doses of 1 to 3 drams. 
It must be freshly ground shortly before being used, preferably the 
day it is used. 
The copper-sulphate treatment for stomach worms, given on pages 
39 to 41, will also remove tapeworms, 
In South Africa good results have been reported from the use of a 
mixture containing 1 part of sodium arsenite (testing 80 per cent 
arsenious oxid) and 4 parts of copper sulphate. The total dose of 
the mixture is as follows: For animals 2 to 4 months old, 180 milli- 
grams; 4 to 6 months old, 250 mg.; 6 to 10 months old, 375 mg.; 1 
year old, 500 mg.; 2 years old or older, 625 mg. This may be given 
as a powder. Remove food and water the afternoon before dosing: 
dose the following morning; allow food that afternoon and food and 
water the next morning. The dose may be repeated the day after 
the first dose, in which case food is allowed the afternoon after the 
first dose, the animal is dosed the following morning and fed that 
afternoon, but no water is allowed from the afternoon preceding the 
first treatment until the morning following the second treatment. 
Owing to the poisonous nature of arsenic, it is best to test the treat- 
ment on a few sheep to be sure the dose is safe before dosing a flock, 
and the drugs should be kept out of reach of children and animals. 
If the treatment is repeated at intervals of a month or more through 
warm weather, the single treatment should be used. 
The Oklahoma experiment station claims very good results from a 
solution containing 1 per cent copper sulphate and 1 per cent by 
weight of snuff or powdered tobacco. The tobacco is steeped over- 
night and the copper sulphate then added. The cose is 50 mils (about 
14 ounces) for lambs and twice this amount for full-grown sheep. 
Prevention.—No dependable preventive measures against these 
tapeworms can be recommended, owing to the-fact that the life 
histery is unknown. 
THE FRINGED TAPEWORM.” 
Location.—This tapeworm is found in the small intestine, the gall 
ducts, gall bladder, and biliary canals of the liver, and in the duct 
of the pancreas. 
Appearance.—These are whitish or yellowish tapeworms and may 
be a foot long (fig. 14), but are commonly shorter. They may be 
readily distinguished from other tapeworms by the fact that each
