What to do. — Treatment is of little avail. If the difficulty could be 

 known in time, daily small doses of sulphur and saltpetre, given for some 

 weeks, might pass the eggs from the bowels ; yet this is not certain. 

 Keep the dogs about the place free from tape worms by occasional 

 vermifuges, and burn all their dung when found. 



Vm. Trichina Spiralis. 

 Trichinae are found in all animals, but usually in man, the hog and the 

 l^t. They are almost microscopic, varjing from one-eighteenth to one- 

 of an inch in length, and are among the most fatal of parasites. 

 The mature and fertile worm lives in the intestines 

 of animals, while the immature lives in cysts in 

 the muscles. When the eggs first hatch, the young 

 ones migrate through the intestines, and find their 

 way into the voluntary muscles, that is, the mus- 

 cles of motion ; and in the course of six weeks 

 they become encysted, and do no farther harm to the 

 man or animal containing them ; but during those 

 six weeks the life or death of the victim is merely 

 a question of strength to withstand the pain, ex- 

 haustioM and emaciation, and many people die from it. 



How to know it. — The symptoms are swelling and great soreness of 

 the muscles affected ; pain ; emaciation and exhaustion ; it is often mis. 



taken for rheumatism. In the 

 lower animals, the same S3aiip- 

 toms are seen as in man, but 

 to a less marked degree ; there 

 is loss of appetite ; stiffness in 

 the hind parts ; the muscles are 

 sore, and the animal is loth to 

 move. Tf those affected live

through the six weeks, they will recover. 



What to do. — During the six weeks give alcohol in half-ounce doses, 

 three times a day in gruel, and a teaspoonful of sulphur in the food 

 morning and night. 



Prevention.— For people — never eat underdone pork, for trichinaj sur-. 

 vive 140 ^ F. Hams thoroughly smoked and boiled are safe. 



For hogs keep them remote from slaughter houses, and never feed 



them on Uie offal from slaughter houses. Keep their pens free from 

 rats and mice. Pork fed on slaughter refuse, or kept near a slaughter 

 house, ou^rht to be examined with a microscope before being eaten.
