SOME CANINE DISEASES AND THEIR REMEDIES. 673 



oughly rubbed into the skin, every part of the body, neck, 

 and even head, where possible, being treated. This should 

 be done every night for ten days. If he is a house-dog, he 

 should be well washed every morning, for obvious reasons, 

 but the sulphur and lard should be applied again at night. 

 If sarcoptic mange is present, the insects ought to all be 

 destroyed by the fifth or sixth day; to continue the appli- 

 cation is, however, advisable, to make sure. After this 

 treatment has been administered, one may be reasonably 

 certain that his dog has not the form of mange in question, 

 and if an eruption remains, the chances are it is eczema, or 

 the other form of mange, which will next be described. 



Everyone who has seen a case of what is known as 

 barber's itch can readily understand the appearances pre- 

 sented by the least common form of mange, the ' ' f ollicu- 

 lar." This affection runs the same course, with identically 

 the same phenomena, as is observed in the parasitic sycosis 

 of the human race. Again, it is known that follicular 

 mange in the dog, and a kindred disease in the cat, has been 

 communicated to man, and in him given rise to parasitic 

 sycosis. Further proof of the analogy of these diseases has 

 been presented by the microscope; under it there has been 

 found, on the roots of the hairs drawn from a dog suffering 

 from follicular mange, the same form of parasite which 

 causes parasitic sycosis in man. 



It is evident that, with but one exception, writers on 

 canine diseases have been satisfied to accept, unquestioned, 

 an old theory that the form of mange under consideration 

 was caused by an animal parasite, called the acarus fol- 

 liculorum, which is identical with a parasite, bearing the 

 same scientific name, in man. This harmless animal, 

 known also as the " pimple mite," everyone is familiar with, 

 having pressed them from the face and nose, inclosed in 

 little cylinders of cheese-like substance with black heads, 

 the latter being accumulations of dust and dirt. Owing to 

 their resemblance to maggots, these deposits the natural 

 contents of the sebaceous glands are considered worms by 

 the ignorant, who denominate them skin or face worms.
