By this, as alfo by what follows it appeajis,^ that Dr. H, did read my 
BoGk,whiIe I created of the Minerals, very foperficialiy , or elfe had mnch 
forgotten when he writ that Letter. Nothing is more plain, than chat oiir 
Water hath imbibed Alome, infonfiuch that Mr. S. in the former p irt of 
his Book againO: me owns nothing elfe almofi but Aiome. And for the ad- 
ftringent, &c. property of Alome, it ii very true, what Dr. >/r Aieh, to
