DISEASES OF THE HOG. 105 



the compound syrup of squills in doses of from 

 twenty to thirty drops three times a day will be 

 found serviceable. At this stage of the disease 

 opium should be avoided as it is apt to arrest the 

 secretions or prevent the expulsion of mucus from 

 the small bronchi and therefore increase the dis- 

 tress and danger. It is better in the case of the pig 

 not to restrain the cough, as it is often an effort of 

 nature to expel the accumulated mucus. If the 

 cough should be very distressing recourse may then 

 sometimes be had to the fluid extract of hyoscya- 

 mus three to five drops at a dose every two hours 

 or hydrocyanic acid ip doses from five to fifteen 

 drops every two hours. In the advanced stages 

 when it appears to be verging on a chronic form, 

 take one ounce of the bruised roots of senega and 

 licorice, boil this in one and one half pints of water 

 down to a pint, and w hen cool add one grain tartar 

 emetic and tw^o ounces of sugar, and give the ani- 

 mal a tablespoonful of this every two hours. If the 

 pig is weak, give it five to ten grains of carbonate 

 of ammonia in a little cold water every two hours. 

 The animal's strength should be supported by good 

 milk or eggs beaten up and a little whisky added 

 to it. Keep the animal as comfortable as possible. 

 Post Mortem Appearances. — The bronchial mu- 

 cous membrane is reddened, thickened, sometimes 

 softened; in some cases there is ulceration and gan- 

 grene. Occasionally the redness is diffused, but 

 more frequently in patches. In some few cases 

 there will be abrasion. The tubes contain mucus in 

 various states^ sometimes blood and not infi^equent-
