DISEASES OF THE HOG. . el 
this and migrate to other parts of the body, where 
their presence causes great disturbance. The | 
eggs of this worm pass from the hog and are 
eaten by the grubs of certain large beetles; in the 
stomach of these grubs the eggs develop into em- 
bryos, or rather the embryos already developed 
are set free and bore through the intestine and lo-

become encysted and remain dormant until the 
grub is eaten by the pig and then once in the stom- -

worm at once. The color of this worm is white or 
bluish white, the female being from five to twenty 
inches in length, while the male is from three to 
five inches long. The female is very prolific, pro- 
ducing immense numbers of eggs, which are of a 
somewhat oblong-oval shape. 
Symptoms: Pigs may have a number of these 
worms without their causing any noticeable de- 
rangement; on the other hand they often derange 
the digestion and assimilation, causing loss of 
flesh and a general unhealthy appearance. The 
animal is usually hungry and may eat large quan- 
tities of food and yet remain thin. When a pig has 
such symptoms with the absence of any other ail- 
ment we may suspect that worms are the cause. 
In very bad cases the pig becomes weak in the loins 
and the membrane in the corners of the eyes 
swollen, red and watery; the animal suffers pain, 
which is indicated by it continually grunting or 
squealing; such hogs are usually bad tempered 
and will bite and snarl at the other pigs. In some
