PARASITOLOGY. 10^ 



Parts hifesied. — The small intestines. 



Symptoms. — The puppy is most often infested, 

 though we find them in older dogs. About forty- 

 percent of the dogs are infested. The parasites cause 

 irregularity of digestion, as diarrhoea, colic, nervous- 

 ness, irregular appetite and unthrifty appearing coat, 

 and later emaciation. If the parasites ascend to the 

 stomach, nausea and vomiting are noted. The bowel 

 may be occupied by large masses of these worms ; 

 the passing of the worms is a diagnostic symptom. 



Treatjnent. — The dosage should vary with the age 

 and size of the animal; puppies take one-half grain 

 santonin with five to ten grains areca nut. As the 

 dog grows the dose of santonin may be increased 

 to three or four grains, according to age and size. 

 The dosage of powdered areca nut is one to two 

 grams for each pound weight ; the areca nut is an 

 intestinal irritant and acts as a purge. 



Santonin, 2 grains ; Arecolin, ^/^^ grain ; Calomel, 1 

 grain ; Chelidonin, 3/4 grain. This has worked excel- 

 lently both in dogs and hogs, ridding the intestinal 

 tract of round worms. 



AscARis Mystax (Mystax — mustache). 



Synonym. — Ascaris felis. 



Distribiitio?i.—Yoyxn6. common in America and 

 other countries. 



Description. — In regard to its anatomical structure 

 it is similar to the Ascaris Marginata of the dog, and 

 by some is regarded as a smaller variety of the same 

 species. 



Animal Infested. — The cat. 



Pa7^t Infested. — The small intestine. 



Symptoms. — If the worms ascend to the stomach
