ajid fo dropping it upon the Tetter, I there could fee it imme - 
diately gather a very thin skiq upon the raw flefli, not unhke 
that which is feen to gather upon Milk over a gentle fire. This 
skin would have fraall holes in it, through which a moifture did 
iflue in fmall drops, which being wip'd away, and the water 
continued to be dropped warm out of the mouth, the holes 
would diminiftij and at laft be all quite healed up. 
For the £y^-?r^^^r/^ I conceived them more ftronglyterfive, 
and clearing the Eyes ; and they had a rough fmartnefs, as if 
they carryed Sand or Gravel into the Eye. 
I have known and try'd three or four healing Fountains 
of late difcovery^or of no old fame that I could hear of. 
I did once put rich i^/i^r/^ for fome days in a veflel of water^ 
to try whether the water would acquire a healing vertue^ 
but my Experiments were interrupted. I had in my thoughts 
many other ways of Tryal j which I may refume hereafter, 
A farther Accomp of the Vitfiolate-water^ 
mentioned Num. iS p. ^2^. Together with 
fome other particulars touching waters. 
This comes from the fame hand as follows s 
I formerly mentioned toyou^thatjifthat Pool of MuPhillip% 
which feems to be of Vitriolate-water, were on my grounQj I 
would drain it, and fearch the head of theSpring^purfuing the 
fource, till I could well difcern^ through what by of Earth or 
Gravel it does pafs. Now I ihali tell you^ that I have taken 
order for the further tryal of the faid Water^by boiling a grea- 
ter quantity in a Furnace, C^r* Butjuft as we were in readinefs 
for the tryal, a ftreamof Rain-water fell into the Pool, and fo 
difcpuragd us for theprefent* I have alfo taken a courfe to 
turn the falling Waters afide, and to drain the Pool, that we 
m^y fee, what the Native Springs ( hether one or more) may 
be. Of which more hereafter. 
I wifli he goes on ) we had a full Accompt of our ijfl/^- 
Springy zt Droyt^wycb near Worcefiery and at Nant-wych in Che» 
J^ire (what other Salt-Springs we have in England, I know not :)
