564 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



French chemists. The plant was found in a moist soil ninety 

 miles inland, near the River Corao. The root is from twenty 

 to twenty-seven inches long, and from one third of an inch to 

 one inch in diameter. The bark is reddish, and the color be- 

 low the epidermis bright red. The wood is grayish-white 

 and hard. The experiments were made chiefly with the bark, 

 but some with the wood and root. The infusions, even when 

 very weak, are extremely bitter, and with iodide, of potassium 

 yield abundant precipitates. Alcoholic are more powerful 

 than the aqueous extracts. Four grains of extract dissolved 

 in water, given to a dog, produced violent tetanic convul- 

 sions, but in two hours the animal recovered. Six grains 

 killed a dog in twenty minutes, the animal dying of asphyxia 

 and tetanic convulsions. The action of the poison is very 

 rapid, but fatal consequences may be prevented by artificial 

 respiration. IV A, September, 13~[. 



REMEDY FOR CARBOLIC ACID POISONING.

 England, during the past fall, from having eaten acorns that, 

 had fallen off during a gale. When once taken ill, death fol- 

 lowed more or less quickly in each case, no remedy being suf- 

 ficient to allay the resulting inflammation, The poison ap- 

 peared to induce a blackening and rotting away of. the mu- 

 cous membrane. Newspaper. 



CALOMEL A POISON FOR MICE. 



A preparation of one part calomel, five parts of wheat flour, 

 one part of sugar, and one tenth of a part of ultramarine, all 

 mixed together in fine powder and placed in a dish, is said to 

 be a most efficient poison for mice. 15 C, xil, 191. 



TURPENTINE AN ANTIDOTE TO PHOSPHORUS. 



It is said that oil of turpentine is a very powerful antidote 

 to phosphorus poisoning, the experiment having been tried 

 successfully upon dogs. 9 C, 1870, 78.
