MANGE. 275 



ovoid bloated bodies, claws with tenacula at their extremities, besides 

 legs and tails. They moved but tardily, after the manner of crabs, 

 apparently dragging their bodies by hooks or tenacula in their feet, 

 always making, along some hairs, towards any heap of skin or scales, 

 in which they buried themselves so completely that the glass could take 

 no further cognizance of them. 



Oct., 1851. — Discovered acari in Lieut. Walsh's second charger. It 

 had had the mange in the summer, and had been several times thoroughly 

 dressed, both at the Regent's Park Barracks, and at his father's ; the animal 

 came up this month, and was thought cured. It, however, commenced 

 rubbing again, and we found upon the sore places acari. It is now 

 shaved all over, that being found preferable to clipping or singeing, and 

 is dressed with the Ung. Picis. 



CoMMUNiCABiLiTY OP Mange AND Itch. — Profcssor Cole- 

 man says, " Mange is the most contagious disease to which 

 the horse is liable ; more so than glanders. I have known 

 horses to be attacked with the disease from being curried 

 with the same comb as had been used about one that was 

 mangy ; and I have often thought that persons attending 

 on mangy dogs have communicated the disease to horses/^ 

 — Mr. Blaine declares, unhesitatingly, "that the mange of 

 one (animal) can be communicated to the whole;'' and 

 adds, he has witnessed several cases where the itch has 

 been taken from mangy horses.^' — These English authorities 

 are supported by continental veterinarians : 



A farmer purchased a mangy horse, and rode it to his house. The 

 next morning he found he had got the itch, and which his son had likewise 

 caught. The boy who groomed the mangy horse scratched himself greatly 

 the second day afterwards ; in fine, thirty persons caught the itch, and 

 some horses the mange. — In the Annual Report of the Veterinary School 

 at Lyons, occurs an account of a mangy horse having communicated the 

 disease to two cows, and to several persons. In the same Report is 

 mentioned the case of a pupil at the School who caught the disease in his 

 hands and arms from rubbing a mangy dog. — Ilurtrel d'Arboval records 

 an observation of the same kind. " An inhabitant of Montreuil-sur-Mer 

 bought a pair of fine carriage-horses, both mangy. His servant, to 

 whom he gave them in charge, caught the itch in his chin ; and what is 

 remarkable, he contracted the disease nowhere else." — Such cases as 

 these, however, after all, are rare : and there are those who disbelieve in 

 the communicability of mange from one species of animal to another.
