tcenia expansa . In severe cases the sheep becomes so weak 
that it is with difficulty that it keeps up with the flock when 
grazing. They are attacked with convulsions, finally a malig¬ 
nant diarrhoea which refuses to yield to treatment, the animal 
gets down, unable to rise, and succumbing by exhaustion. 
Treatment .—This is also both curative and : preventive. Where 
tesnia expansa is in a flock all the animals should be dosed, as 
the well ones if allowed to graze in the same pastures as those 
already affected are sure to pick up the eggs of the parasite and 
in turn become mediums for its distribution. Before administer¬ 
ing vermifuges to the sheep they should be prepared for the 
same by being kept without food and water for at least twelve 
hours ; they should be all dosed at one time and be kept con¬ 
fined for at least twenty-four hours after receiving the medicine, 
so that the segments and eggs which will be expelled are not dis¬ 
tributed over the pasture. When we are satisfied that the med¬ 
icine has had the desired results the sheep should be allowed to 
go to a new pasture and the yard in which they were confined 
should be thoroughly disinfected to destroy all evidence of the 
disease. One of the best and simplest taeniacides to use is ka- 
mala ; this is obtained in the form of a coarse red powder, its 
effect on the sheep for expulsion of the tape-worm being very sat¬ 
isfactory, and the nearest to a specific of any medicine I have 
ever used. Take kamala 3 drams, mix thoroughly in 3 ounces 
of linseed gruel ; this is the dose for adult sheep. Lambs take 
from one to two drams according to their age and size. This 
should be given very slowly to the animal to insure its passing 
into the fourth stomach and so on into the intestines, as if it 
should be hastily given it is liable to enter the rumen, where its 
effect would be lost; this treatment should be repeated in a 
week. Out of 92 lambs and sheep treated by me under this 
treatment, I did not lose a single case. 
Preventive Treatment consists in not overstocking the pas¬ 
ture. Attention must be paid to the water supply, as this ap¬ 
pears frequently to be a source of infection.
