ioo The Triumphal Chariot of Antimony. 



Pour over the Antimony some 

 highly rectified vinegar, subject to di- 

 gestive fire, or, in summer, expose to the 

 rays of the sun, shaking it once and again 

 every day.* 



Let this slow digestion be con- 

 tinued till the vinegar assumes a yellow, 

 or rather a reddish, colour, like that of 

 well purified gold. Then pour off this 

 clear and pure extracted substance, add 

 more vinegar, and repeat the same pro- 

 cess till no more gold-coloured Tincture 

 can be extracted. Mix all the extract, 

 filter, place in cucurbit, put on lid, distil 

 the vinegar in S. Mary's Bath, till there 

 remains at the bottom a gold-coloured 

 powder approaching red ; pour on this 

 powder distilled rain water ; let it evapo- 

 rate by distillation, add more rain water, 



* When I followed this latter direction literally, the sub- 

 stance became solid like a stone, and stuck to the bottom of 

 the vessel, so that I could not get it off. At length, being 

 warned by experience, I shook the vessel five or six times 

 daily, stirring the substance with a wooden spoon, and you 

 will be wise if you profit by my experience in this matter, not 

 only as regards the present experiments, but in the prepara- 

 tion of the glass, and in every exti action of the tincture of 

 Antimony.
