areca is itself purgative. If feces are not passed in the course of four 
or five hours, it is advisable to give castor oil or some other purgative. 
As noted previously, areca nut must be freshly ground to be effica- 
cious. 
Kamala—tThis may be given in-doses of half a dram to 2 drams 
(a half teaspoonful to 2 teaspoonfuls). The powder may be given 
in sirup and will not need to be followed by a purgative, as kamala 
itself is a purgative. As in the case of areca nut, if feces are not 
passed in four or five hours 
castor oil or some other pur- 
gative should be given. 
Any tapeworms that are 
passed and the feces with 
them should be burned. On 
the farm this is easily done 
by using hay or straw for 
fuel.

cess to it. The use of the 
tank has apparently resulted in a diminution in the number of 
cases of this parasite in sheep and dogs, and the extension of 
this measure will probably eradicate it in time. Dogs should be 
kept free from tapeworms by suitable remedies, whenever necessary, 
and it would be advisable to give such treatment as a routine pro- 
cedure about four times a year where there is any chance of dogs 
eating infective material. Stray dogs should be kept off farms and 
suppressed by appropriate. measures. , 
SHEEP MEASLES. 
Location.—Parasites known as sheep measles occur in muscles, in- 
cluding the heart, and intermuscular connective tissue, and as de- 
generate cysts in the lungs, walls of the first and fourth stomachs, 
and the kidneys. 
Appearance.—This parasite occurs in the meat (meas.y mutton) as 
oval cysts 3.5 to 9 mm. (one-seventh to one-third of an inch) long 
by 2 to 4 mm. (one-twelfth to one-sixth of an inch) wide. These 
cysts have a thin external membrane inclosing a clear fluid. On
