GLANDERS 193 



while no effect is produced in a healthy animal except a 

 trifling rise of temperature. 



There is no record of any successful attempts to treat 

 the disease in this way, mallein being employed for 

 diagnosis only. Quite independently many horse-owners 

 have adopted mallein as a test, and have isolated the 

 reacting. This procedure on the part of horse-owners has, 

 however, received a rude shock by a case in which it is 

 stated that a practitioner had used mallein in a stable with 

 a view of isolating those animals which had reacted, though 

 yielding no clinical evidence of glanders. Ten animals gave 

 typical reaction. One of the Council's inspectors visited 

 the stable subsequently, and at once placed the official 

 label on them. This mode of proceeding, though possibly 

 technically correct, will, it is to be feared, have a deterrent 

 effect on horse-owners in London, which affords nearly 

 80 per cent, of the cases recorded in Great Britain. 



Preventive Measures. — All horses suffering from suspicious 

 discharges should be examined, and, if found to be suffer- 

 ing from glanders, should be forthwith slaughtered and the 

 carcase burned, special care being exercised in handling it. 



The stables and all clothing which may be contaminated 

 should be carefully disinfected with mercuric chloride. 



SYPHILIS. 



Syphilis appears to belong to a group, the other members of which are 

 tuberculosis, leprosy and glanders — Lustgarten's bacUlus is probably 

 the specific organism — Some observers have described streptococci — 

 Methods of stairdng — Growth on media — BaciUus of Eve and Lingard 

 — Capsulated diplococcus of Disse and Tagucchi — V-shaped bacUlus 

 of Dr. Van Neissen — The Contagious Diseases Act. 



Several observers have described various organisms as 

 the cause of syphilis, but, with the exception of the bacillus
