THE CONQUEST OF DISEASE

one of the most common and fatal of the dis- 

 eases of the horse. It was formerly regarded 

 as noncontagious, and animals thus affected 

 were sold to truckmen, farmers, and street 

 railroads, and disseminated the malady. The 

 disease is inoculable to man ; and when we look 

 into the older text-books on surgery we find 

 how much attention it required. Now but little 

 space is given to it, and there are few surgeons 

 of the younger generation who have ever seen 

 a case of glanders in man. In 1837 the French 

 surgeon Rayer was struck by the resemblance 

 of a disease called putrid fever, occurring in 

 man, and glanders of the horse; and since this 

 disease was usually observed in grooms and 

 stable men, he undertook to prove or disprove 

 its identity. He inoculated a horse with the 

 discharges taken from a sore on a patient hav- 

 ing putrid fever; and the animal developed 

 glanders. With this beginning he proceeded 

 to prove the communicability of the disease 

 from one animal to another. The story is a

 seems simple enough, but wringing from na-
