bringing the faid Dr. Winks conftituent Principles of thofe Wa- 
ters to the Teft, he could not find them there y nor, upon a tho- 
row examination of the Vertues afcribed to them , fee caufe to

hath endeavouf d to make it out by fevere Trials and Obfervati- 
ons 3 that the five Ingredients aflign'd by the faid DoEior , viz* 
Iron, Vitriol, Alhm, Niter , and Sea-Salt^ are not there, as

all , but toaflert thofe, which he finds there demonftrable by 
Experiment; and thereupon affirms, that that^ which indeed 
gives the Eflence to this Spaw, is an acid Aluminous Mineral 
Salt y preying upon and diflblving a flight touch of the Mineral

that in the Efurine Salt of Allom are as noble medicinal Vertues 
to be found, as in any other Mineral fpecificated Salt whatever *
