182 DISEASES OF SWINE AND OTHER ANIMALS. 



was Berkshire, crossed witii Poland China. Owing to the inland situa- 

 tion and want of necessary articles at the place the troug-hs were not 

 made with circular holes, but were constructed in the following manner: 



The trough was di- 

 vided longitudinally 

 by a board on edge so 

 that the hogs could 

 feed on either side 

 withoiit permitting 

 the admission of the 

 feet, thus : They were 

 graded 1, 2, 3, 4, according to age and condition. The herd was suffer- 

 ing from both modes of attack, as heretofore described. They were 

 moved from their range and placed on new ground. As a general thing 

 the younger hogs suffered the most. 



Pen No. 1 contained the oldest hogs, jifteen in number, from one to 

 three years old. 



Pen No. 2 contained fourteen head, from eight months to one year 

 old. 



Pen No. 3 contained eleven head, from five to eight months old. 



Pen No. 4 contained five head, from five to twelve months old, and 

 was the dead 'pen. 



No food was allowed for the space of twelve hours. Nos. 1 and 2 

 were given salt and water, which they were comijclled to drink, being 

 without food or water. This had the effect of causing vomiting and 

 purging. In several cases worms were discharged from the stomach 

 and bowels ; principally from those suffering from the second mode of 

 attack. Some had to be pressed forward and urged to drink. After the 

 action of the salt the tincture chloride of iron was administered in water in 

 doses of twenty drops every four hours, for the older, and fifteen for the 

 younger hogs. A mash of bran was made (which was always fed while fresh 

 and sweet), and they were allowed to partake moderately of the iron half 

 an hour after the first dose. They were fed at intervals between the doses 

 of iron, and no other food was given until convalescence began, when they 

 were allowed some com in connection with the mash. In those suffering 

 from the disease in the first mode, there was constipation of the bowels, 

 dry noses, and watery discharges from the eyes. When the bowels were 

 moved (and in some instances they were very torpid), the passages would 

 be stercoraceous, and covered with a white substance (apparently epi- 

 thelium), were very hard, and upon examination appeared to be com- 

 posed almost entirely of earth. These began to improve on the third, 

 and were so much improved on the sixth day that they were allowed a 

 more liberal supply of food. They were not considered out of danger 

 until the eighth or tenth day. It was not necessary to give any other 

 purgative, and gxadually the discharges fi'om the bowels became of a 

 proper consistency. 



No. 3, Most of these had dianhea. Some had a cough, and whenever 

 a fit of coughing came on there would be a profuse discharge from the 

 bowels, thin and of a yellow color. Occasionally there would be vomiting 

 also, showing the great irritability of the pneumo-gastric nerves. Worms 

 would also, ',\\, times, be ejected from the stomach or bowels. To these 

 were ivdniiiiistered from one and a half to two fluid ounces of raw linseed- 

 oil, according to th(i age of the animal. After the action of the oil the 

 discharges weiv not so frequent, arid the animals seemed more lively. 

 Twenty droiis orcailtolic acid were then administered to the older, and 

 fifteen to the younger hogs every jbiu- hours.
