The Poifon, when thup infpiffated, 

 is liquifiable by heat, and diffoluble in 

 water, in alcohol, in fpirit of fea-falt, 

 and in a volatile alkaline fpirit, as alfo 

 in blood, faliva, &c. except only a very 

 fmall part, which fubfides both in a fpi- 

 rituous and aqueous menftruum, and 

 probably confifts of earthy particles fo- 

 reign to the compofition. It unites 

 with acids without emotion, or change 

 of colour. On mixing it with alkalies 

 no ebullition is perceptible, but the co- 

 lour changes from a reddifli brown to 

 a yellowifh brown. A few grains, mixed 

 with as many ounces of human blood, 

 warm from the veins, intirely prevents 

 a feparation of ferum and craffamen- 

 tum, and the whole mafs continues 

 united in a ftate of fluidity, limilar to 

 that in which it is drawn, until after 

 fome days it putrifies.
