118 PARASITOLOGY. 
Symptoms.—This is a serious form of intestinal 
strongylosis, often causing great loss among cattle 
and sheep. The first symptoms are those of diar- 
rhoea loss of appetite, followed by gradual loss of 
condition. The mucous membranes become pale, 
due to the loss of blood; the hair becomes rough; 
there is great thirst and languor; swellings may be 
noted about the head and chest; the skin becomes 
dry, hence the condition has been called paper skin. 
The animal may die. 
Treatment.—Kamala, thymol, benzine, turpentine 
and gasoline have been given with more or less good 
results. The best results are probably derived from 
the following treatment: Tocattle that have fasted 
over night give two to six ounces of gasoline once 
a day for four or five days. The first day give one 
to two pounds of Epsom salts. To lambs and sheep 
give two to eight drams of gasoline, after fasting, 
and drench with the proper amount ‘of salts, as in 
cattle. It is recommended to give gasoline in doses 
sufficient to make the animal show symptoms as 
though drunk.
