494 DOGS USED FOR SPORT. 



For reasons obvious, the back is most seriously affected ; the dis- 

 ease being milder and less marked toward the extremities. The 

 canine acarus is not identical with the human parasite, and cannot 

 live in the integuments frequented by the latter. 



The treatment as usually laid down, is as nauseous to the owner 

 of the animal as the disease itself. There is no reason for this 

 whatever. Wash your dog thoroughly with warm water, and Cas- 

 'well. Hazard and Co.'s " Jtmiper Tar Soap" ; none other, and 

 administer an occasional cathartic. Saponaceous compounds as 

 3?, 33 may be used to advantage, the animal being easily cleaned 

 thereafter, and possess the advantage of not soiling the habiliments 

 of the person who applies them. 



If the above fail, 34 thoroughly rubbed in and allowed to dry 

 will prove infallible. 



This disease is readily diagnosed from the fact that while the 

 skin is partially denuded of hair, that which remains is coarse and 

 unnatural to the touch, and looks all awry and unthrifty. The 

 skin too, if not absolutely red and inflamed, is dry and scaly. 



Trichoses Fttrfuracea Canina. Ring Worm of Dogs. — This 

 too, is known as mange. I give it the above title as most applica- 

 ble, it most resembhng Trichoses furfuracea as exhibited in the 

 human subject, and apparently depending upon the same causes. 



My attention was first called to the similarity some years since 

 when a medical student, by the late Prof. Howard Townsend, of 

 Albany, New York. 



The hair partially falls off, and the disorder is well marked by 

 bare patches of small dimensions appearing upon the most promi- 

 nent angles of the body, so as to lead one to suppose that they 

 were the result of chafing. And so they are, but there is a cause 

 for the rubbing. 



In the early stages of the attack, the only appearance of dis- 

 order that can be detected is a thin layer of scurf, either in sepa- 

 rate scales around single hairs, or in patches, including several, or 

 a more considerable number. This formation is accompanied by 

 a slight degree of itching, which is relieved as soon as the scurf is 

 torn away by rubbing against some convenient post. At a later 

 period the skin upon which the furfuraceous scales are dusted ap- 

 pears reddish and slightly raised ; the papillae next make their ap-
