DISEASES 35 



Johns Hopkins Hospital reports two cases of hookworm treated and cured 

 with oil of wormseed where thymol had failed. He also gives the 'coeffi- 

 cient of efficacy' in the same percentage as the article you have quoted. 

 He gives the following mode of administration: First day— Liquid diet; 

 8 p. m. one ounce Epsom salts. Second day — Omit .breakfast and lunch; 

 at 5 a. m. one ounce of Epsom salts; at 7, 9 and 11, sixteen drops of oil 

 chenopodium on a little granulated sugar; 1 p. m. one ounce castor oil 

 containing fifty minims of chloroform; soft supper (this for a dog would 

 be a little baker's bread soaked in milk). Third day — Resume full diet." 



Another southern writer has this to say: 



"While it has not been definitely determined whether or not this dis- 

 ease is due to hookworm infestment, indications suggest a very close relation, 

 as postmortem examinations have shown hookworms and great intestinal 

 inflammation. Ii is probable that the toxin which the hookworm injects 

 into the dog's blood may cause the disease. It is not contagious, nor 

 can it be communicated by feeding or drinking from the same vessel. An 

 experiment was recently made by feeding parts of stomach and intestines 

 of a dog which died of an acute case of black tongue to several healthy 

 dogs, and no ill effects developed. Another fact that is quite apparent is 

 that black tongue is never found except in sections of the country, which 

 includes the entire South, where the hookworm is known to exist" As to 

 the treatment for hookworms, see "Hookworms" in the regular worm 

 article. 



Colic. — This subject is very completely covered by Dalziel. 



"Nearly all domestic animals are subject to attacks of colic, or pripes, 

 as it is more frequently termed, especially when the horse is the subject 

 of the disease. In the dog, puppies are especially liable to it, but it attacks 

 dogs of all ages, and, if not promptly attended to and properly treated, is 

 very liable to end in inflammation of the bowels — a most dangerous dis- 

 ease, which, in some* of its features, though happily not its dangerous ones, 

 colic resembles. One very important point of distinction is, that whereas 

 inflammation comes on gradually, and feverishness, with hot, dry nose, etc., 

 always exist as premonitory symptoms, colic comes on suddenly, and a dog 

 eating well and seeming in perfect health is seized with spasm of the 

 coat of the bowels, causing such pain that he gives voice to a low moan, 

 which is afterward changed to a prolonged howl, as the paroxysms of pain 

 increase in frequency and severity. In colic, too, the nose and mouth are 

 cool, and there is no offensive breath. As in inflammation, the attitude 

 is peculiar and unmistakable; the back ebing arched, the feet drawn in 

 toward each other and the tail tightly tucked between his legs; in colic, 

 the belly is sometimes distended considerably with gas, and is then known 

 as flatulent colic. It is a disease of frequent occurrence in dogs, and the 

 exciting causes are various; exposure to wet and cold; getting dogs, espe- 

 cially house dogs, to swin in cold inclement weather, are common causes; 

 the presence of worms in the intestines also produces colic. But the most 

 common cause is undoubtedly the giving of improper food; sugar and
