How to Know It. 
There may or may not be, but generally is, a discharge from the noso, 
running of the eyes, weakness of the hind parts, and general ill health. 
By examining the skin, small watery pimples will be found of a pink or 
red color. The remedy is undoubtedly beyond the reach of medicine, 
though a so-called specific is small doses of sulphur and saltpetre, given 
daily for weeks. The prevention is, to put no human excrement on graz- 
ing fields, to keep dogs clear of tapeworm by an occasional vermifuge, to 
bury all excrement of dogs found in the pastures, and to kill all stray and 
worthless curs. v 
The Lard Worm. 
There is another parasite of the hog, the lard worm ( Sleplianarus Den* 
tatus ), from one to one and three-quarters of an inch long, which is 
occasionally fouud. in all parts of the body ;of swine is frequent in tha 
liver, kidneys and fat around the ribs, and in various organs of the body, 
including the heart. When present in large numbers, especially in the 
kidneys, its eggs may sometimes be discovered in the urine, by means of 
the microscope. Another worm, Eustrongylus Gigas, also inhabits the 
kidneys ; both may produce weakness of the back, but it would not be 
safe to treat for these parasites, unless this was surely determined by 
the microscope. 
What to Do. 
Do nothing. Various remedies have been prescribed, such as small 
doses of sulphur and salt, given daily for several weeks, or small doses 
of salt and turpentine. Neither have certainly been known to do any 
good. Minute doses of arsenic, one-eighth of a grain, given daily for 
two or three weeks, so it may be taken up by the system, would be the 
proper course indicated. The better way is to prevent their getting 
measly, by keeping the diseased ones entirely from the well ones, and the 
young away from the old. 
Trichina Spiralis. 
This minute parasite is capable of infesting all domestic animals, includ- 
ing man. The mature and fertile worm lives in the intestines of the 
animals, and the immature worm in cysts in the muscle. The eating of 
rats, and other vermin, and slaughter house offal is the prolific source 
from whence they come. The prevention is obvious. They are rarely 
found in western farm-raised, corn-fed hogs. There is no danger from 
•ating pork infected with trichina, if it be thoroughly cooked, ihei o is
