lill^!ec•d oil tan be .uivt'ii. lU'<;tal iuji'i-tioiis of suupsiuls may lie neces- 

 sary to relieve the constipation. If diarrhoea is a symptom of .the dis- 

 ease, nitrate of bisnnith in dram or half dram doses can be given two or 

 three times a day. As a connter-irritant, oil of turpentine may be ap- 

 plied to the walls of the abdomen and covered up until the skin is quite 

 red. The best diet is well-boiled thin gruels. This should be fed until 

 the hog is able to digest the ordinary ration. 



Toxic Gastro-Knteritis.— Meat brine and washing powders are the 

 most common causes of poisoning in swine, and are ahvays accompanied 

 by an inflammation of the intestines and stomach. 



Poisoning by Meat Brine.— Brine from meat barrels is sometimes emp- 

 tied Avhere hogs have access to it and when eaten will cause an intense 

 intlanimation of the stomach and intestines. Hogs Avill not eat too much 

 salt if they have access to it at all times, but the meaty taste of meat 

 brine probably adds to their desire for it, and is eaten in large quantities. 



Syniptcjuis.— These develop in a short time. The animal is restless at 

 hrsi. will run from ouo place to another, lie down and get up again,

 fuse, watery diarrhoea will come on if the hog lives long enough. Cou- 

 Milsions occiu", during which it Avill throw itself around violently and 

 froth at the mouth. The intervals between the convulsions become 

 shorter and shorter as death approaches. The posterior parts are par- 

 alyzed and the animal will drag itself from place to place. The duration 

 of the attack will vary from a couple of hours to several days. The ani- 

 mal is sometimes suspected of being mad unless the cause is known. 



Lesions.— Upon post-mortem the lining memlirane of the stomach and 

 intestines is found loosened, sometimes in masses, and there is intense 

 congestion of the entire wall and the peritoneum in contact with it. 



Treatment.— The hog should Ije given all the water it will drink. Lin- 

 seed oil in large doses can be given. Flaxseed tea is also useful. To 

 quiet the pain at intervals a teaspoonful of laudanum can be given. 

 Treatment is seldom successful. 



I'oisoning from Washing I'owders.- It is a common practice to save 

 the dish water as slop for pigs. Hogs fed on such slops often sicken and 

 die. the symptoms and course of the disease being verj' much like chol- 

 era. 



Symptoms. —These are diarrhoea, vomiting, fever, lameness, partial 

 paralysis, n(>rvous disturbance and death. The course of the disease is 

 from a few hoiu's to several days, apparently depending on the amount of 

 alkali ingested at one time. Death occurs in the majority of cases. This 

 trouble is gn-atly confused with cliolera. 



Lesions.— TTpon post-mortem examination, the lymphatic glands along 

 the bowel are found swollen and dark colored. The mucous membrane 

 lining the iniestiiics is jtale ;ind shiny. Other internal organs are also
