 feed, as bran and middlings, or middlings and corn meal, or 

 ground oats and corn mixed, and then stirring into this the 

 proper quantity of medicine. Animals that are very sick and 

 that will not come to feed should be drenched with the medicine

TRICHINOSIS TEICHINA. 



Perhaps no other parasite has attracted so much attention as 

 the Trichina Spiralis, which lives rolled up in flesh; it is very 

 small, nearly microscopic, varying from one-eighteenth to one- 

 sixth of an inch in length. Trichina may be found in all 

 animals, but usually in man, the hog, and the rat. If any of the 

 flesh containing trichinae is eaten, the parasites are set free dur- 

 ing the process of digestion. Their growth is extremely rapid, 

 and each female lays an immense number of eggs. From each 

 egg the little worm is hatched, which bores through the walls of
