ETIOLOGY AND PATHOLOGY. 191 



inf- to each person's work, we made use of this in endeavoiir- 

 ino- to discover the cause of death, and had the gratification of 

 having each carcase identified both by owner and shearer 

 himself as bearing the handiwork of the latter, who had 

 skinned the first-mentioned diseased sheep. It may be worthy 

 of remark here that in none of the cases, though there were 

 several small wounds in the skin, could we discover any special 

 lesion at any of these points. 



In woolsorter's disease, internal anthrax, or malignant 

 pustule of man, we have remarkable evidence of the manner 

 in which anthrax may be propagated. This form of the 

 disease is frequently seen among the emvployes in our woollen 

 factories, and has been specially and carefully studied by Dr. 

 Bell, of Bradford, who elicited that the disease is contracted 

 by the workers in wool and hair brought from certain districts 

 where anthrax is known to be common, and by these only 

 when the wool is undergoing a certain process (sorting). 



The materials, working on which is associated with a certain 

 amount of danger, are alpaca, mohair, and camels' hair. Tlie 

 maintenance of vitality of the organism, and the power of 

 transmissibility, are here proved to extend over great changes 

 of temperature and considerable periods of time. That know- 

 ledge of this to us, as veterinarians, is highly important, a 

 report in the Veterinarian for August, 1880, clearly shows. 

 As evidence of the close relation between the diseases of man 

 and the lower animals, this is weU worthy of perusal. We 

 will only say here that in this instance some cattle and sheep 

 died of anthrax, lower doAvn the course of a stream than 

 Keighley, where there are some AvooUen manufactories. It 

 appeared, from information gathered by some gentlemen who 

 investigated the matter, that these animals were supplied with 

 drink from a source contaminated with the ' sud- water ' from 

 certain mills where van and Cape mohair are largely worked, 

 and Avhere handling these several persons had suffered from 

 anthrax. 



In a serious outbreak of splenic fever on a farm, a donkey 

 and a pony were employed at different times for conveying 

 the skins of the diseased ; these beasts of burden died of acute 

 anthrax, probably inoculated through small wounds which 

 existed on the withers.
