Some time before this Work at Shooter s-Kill was 
broke up, fome Pains was taken to difcover the Secret 
thofe had, who fold the Salt fo cheap • and upon exa- 
mining the feveral Salts, that were fold about Town, 
thofe difpos’d of by Mr. George and Mr. Fraiicis Moult, 
were certainly genuine, and were therefore a proper Stan- 
dard to judge of the reft by. But from all the Experiments 
then made, there could no material Difference be found 
between the Salt made from the Waters, and that made 
by them who were in the Secret. There was indeed 
Salt fold by fome, which, in the Courfe of thofe Try- 
als, was found to be a Sal Mirabile, made from the 
0/. Vitrioli and common Salt, but fhot into fuch fmall 
Cryftals, as not at firft Sight to be diftinguifhed from 
the other. 
NecelTity being the Mother of Invention, it was not 
long before it was difcovered, and the Experiment was 
try’d at the Lady Carringtons, Salt-Works near Portf- 
mouth ^ where it was found the fame Thing could be 
done, as at another Work, not far from it, and in which 
Dr. Hoy had been concerned. 
It was fome Years after this Salt had been made at 
Portfmouth, before the Saitmakers at Lemington attemp- 
ted, or indeed knew the Method of making it- who are 
now the greateft Traders in it, and have fent feveral 
Ton in a Year to London, beftdes what has been diredly 
exported from thence. 
I remember it to have been the Opinion of the Pro- 
prietors of the Salterns near Portfmouch, that this pur- 
ging Salt could not be made at any other. Salt-Works 
except theirs, and that the bitter Tafte in the Salt 
was coinmunicated from the Earth to the Sea Water, 
whilft it flood expofed in their Sun Pans. But Time
