Treatment.—Give santonine and sulphate of iron in food, followed bya 
drench composed of turpentine, oil of male fern, and linseed oil. 
Worms.—A few doses of santonine and sulphate of iron (powdered) givel | 
once each day when the pigs’ stomachs are empty, and followed by two or three 
doses of Epsom salts at intervals of about a week, will rid pigs of worms. ; 
few cinders for them to eat, or some charcoal given in the food, will also assist” 
clearing the systems of the pigs and rendering the bowels unsuitable for te 
development of more worms. ‘The dose of santonine for a pig six months ol 
is 8 grains, and of sulphate of iron about 12 grains. 
Arsenic is a dangerous drug, and must be given with great caution. Some 
people say you cannot poison a hog with arsenic, but this is a mistake ; it has 
been done. We would advise that you do not tamper with the drug for this 
purpose. Veterinary surgeons use arsenic in the ease of scabby skin disease’ 
such as eczema, psoriasis, mange, &c. ; 
An occasional dose of Epsom salts is very useful in expelling these worm 
and preventing others developing. 
Secondly, the Strongylus paradoxus, known as the “husk” worm, which # 
found in the windpipe and bronchial tubes, where it sets up irritation, causilg- 
the husky cough well known to many pig-keepers. ! 
Treatment.—A drench composed of turpentine, spirits of camphor, tincture 
of assafcetida, and linseed oil should be given twice a week for one, two, or three 
weeks, according to the severity and continuance of the symptoms. 
Stephanurus dentatus and Trichocephalus crenatus are the names given t 
two other round worms which are rather common in the bowels of pigs 
The same treatment is employed to expel them as in the case of Ascar’ 
suilla. 
Other round worms are also found in pigs occasionally, but, except the 
Trichina spiralis, they are unimportant so far as pigs in this country are 
concerned. 
Trichina spiralis is a minute round worm found in small cysts or bladders 
in the museles or flesh of pigs. 
These worms are transmitted to man, in whom they produce the diseast 
known as Zrichinosis, by the consumption of raw or undercooked pork, and they 
are again conveyed to pigs by these animals eating the excreta and filth from 
affected human beings. Although common in Germany and other continenté 
countries, this disease is not often met with in England, and when an outbrea* 
does occur it is almost invariably from the consumption of foreign hams, &¢ 
Thorough cooking destroys these worms, and it is because hams, &c., are *° 
frequently eaten semi-raw on the Continent that this disease is prevalent ther 
Adult Tapeworms are very seldom met with in pigs, but they (pigs) ofte” 
form the intermediary bearer or host of the encysted form of tapeworms whic 
attain maturity in other animals when partaken of by them in the meat, the 
chief of these being the encysted tapeworm which produces the condition know? 
as “measly pork’’ in the muscles of pigs so affected. Each of these “measles 
‘is capable of developing into the tapeworm known as Tenia solium; and whic 
infests man; hence its importance when occurring in pigs in the encysted oF 
“measle” form, for this worm cannot develop, except by passing this particula? 
stage of its life in the muscles of pigs, and, as it is readily destroyed by 
sufficient heat, the importance of avoiding underdone pork is apparent. 
Two other cystic or bladder worms are sometimes found in pigs, thé 
Cysticercus tenuicollis and the Echinococcus veterinorum, the latter being the 
encysted stage of the smallest kind of tapeworm which infests dogs, and whieh 
is known as the Yenia echinococcus. The cysts or bladders themselves) 
however, often attain an immense size, |
