116 DISEASES OF THE HOG. 
_ or two, but soon a low form of fever sets in and if 
the animal is not relieved will die. On applying 
the ear to the affected side or sides the friction 
‘sound first heard will have disappeared and we 
may be able to detect a light splashing sound and a 
partial or complete loss of respiratory murmur, 
which may enable us to detect how high the effu-

of lymph, and sometimes false membrane will form. 
I have seen some cases that have died when one 
could collect handfuls of this false product. 
Termination: Simple pleurisy of one side usual- 
ly terminates favorably if treated properly and in 
the early stages. When effusion has taken place 
the chances of cure are less, but may generally be 
effected in cases where it is not complicated with 
other diseases. When it occurs in the course of 
febrile affections or in pigs debilitated from some 
other cause it almost always increases the danger 
and often hastens the fatal issue. Pleurisy is often 
present in cases of hog cholera and no doubt it 
helps on the fatal termination of that disease. 
Treatment: First—Give from one to two ounces 
sulphate of magnesia in half a pint of cold water 
and follow this with fluid extract of veratrum 
viride one to two drops mixed with fifteen to twenty 
drops of tincture of hyoscyamus every four hours 
until the pulse becomes softer; after the physic has 
operated if the cough is troublesome and the ani- 
mal seems to be in pain give one grain each of pow- 
dered opium and ipecacuanha in a pill every four 
hours; also give from ten to fifteen grains of nitrate
