life of Corral in his Medicines ; and being my fdf of' 
Opinion, that Corral can be of no manner of Service to 
the Bodies of Men, I took fome of die hneB Red Cor- 
ral that onefliall fee, and put it into Poft Paper, and beat 
it witli a Hammer upon an Anvil to Powder ; after diat 
rput the fame Powder into a clean Giafs,' and poured 
upon it fair Rain-water, till the Particles of theC'orral 
were cover’d with Water ^ then I heated thefaid Water 
fo much, that I caufed it to boil about a Minute, and 
put a little of this Water, after it had hood feme time 
and was grown cokhupon four feveral places,- ‘and trpOn 
the cleaneli Glaffes I cou’d get, to the end that the Wa- 
ter might for the moft part, or rather altogether eva- 
porate , and that I might by this means difeover, whe- 
ther any of the Salt Particles were gone over to the Wa- 
ter ; for in cife none of the Salt Particles fliou’d go over 
to the Water, how can any one fuppofe that Corral has 
any influence upon .our Bodies^ 1 in’ refped to^iouTi 
Health. . ’ . v . f v 
After.that this'Watcr was uitircly evaporated! view- 
ed it carefully, but ‘couM’ difeover nodimg remarkahle . 
in it ; and when I had alfo caufed the clean Rain-water 
to evaporate, I cou’d not but think diar there was no 
other diflerence between that- and the pdier Water in 
which the powder’d Corral was boiled, than that there 
were more Particles in the Rain-water, than in that 
which was bpiled.- 
I alfo viewed the Water, In the bottom of which' the- 
boiled Corral lay,ffeveral times with my naked Eye, fo 
long till the Waterwas in manner, evaporated, but I 
cou’d not in the leafl; difeover any Salt Particles in it; 
and the Water, moreover, remained very clear : In 
fhort, I conclude, that ’tis impoflible that thofe fix’d 
Salts, of which Corral is for the mofl: part compoled,. 
can pofTibly be dilfolved in the Body, but only by 
fharp Salts or by .Fire, and confequently, that itisalto-
