and where they made fuch large Apparatus for ei'a- 
porating the VYater, that they have fuinetimes boyFd 
down 200 Barrels in a Week, from which, in a dry 
Seafon, and when the Land Waters did not get into 
their Drains, they have obtain’d 224 Pound of Salt. 
- After theie Works had gone on fome time. Dr. Hoy 
found out a more expeditious Way of making a purg- 
ing Salt fo nearly refembling that from the purging 
Springs, in all its Properties, that it foon pafs’d on the 
World for the other, and continued fo to do. 
The great Confumption of thefe Salts (which then 
went only by the Name of Epfom Salts) as well at 
Home as Abroad, engaged fome of our Phyficians, (ma- 
ny Years before M. Bolduc took Notice of it) to fu- 
fped, that even what was made at Shooters-Hill was 
fpurious, and received an Addition of fomething to en- 
creafe the Quantity. But thefe Sufpicions, I dare po- 
fitively affirm, were entirely groundlefs, as to the Salts 
made there, and readily believe the fame of any other 
Place, where the Spring Waters were boyled down for 
S lit. But upon a Confideration, that there were greater 
Qjaantities of this Salt confumed than all the Places 
where the Waters were boyl’d could produce, which 
was the real Fad at that Time of Day, there was 
fufficient Room to fufped, that fome of them were not 
genuine, as appear’d to be true fometime after. 
For the Secret, which was then in a few Hands, of 
making thefe Salts cheap, gave thofe, who had it, an 
Opportunity of underselling thofe who made it from 
the Waters, and, in a Year or two, render’d them in- 
capable of making it to any Advantage, confidering the 
Price it was fold for by the others: So that the Work 
on Shooters-Hill was thrown up, and I believe there has 
not been 100 Pound of Salt made from the Waters 
fince that Time, in any Part of the Kingdom.
