192 POISONS USED IN FISHING, HUNTING, AND TRADE 



The disease is acquired in two ways: either by direct contact 

 with the lacquer, or through the fumes arising from it by evapora- 

 tion, but only as long as the lacquer is not dry, for the poison, 

 whatever it is, disappears on drying. 



The symptoms, which develop in a few hours, are fever, with 

 tension and oedema of the skin of the face, limbs, and generative 

 organs, nasal and conjunctival catarrh, while a papular eruption 

 appears on the oedematous skin of the legs and forearms. 



The treatment consists in washing the skin thoroughly with 

 soap and water, and applying soothing applications, such as cold 

 lotions, or Lotio Plumbi subacetatis. 



As prophylaxis the Chinese rub the hands and face with rape- 

 seed oil in which a ham has been boiled, and wear a linen mask 

 for the face and a leather apron for the body. After work the 

 exposed parts are rubbed with a decoction of chestnut, pine-bark, 

 saltpetre, and amaranth. 



The above precautions are taken in China, but in Japan no 

 such prophylaxis exists. 



Note. — Camel poisoning caused by the hydrocyanic acid contained in 

 immuture dura is well known in the Sudan.
