 SIR, 



WE poflefs many excellent elementary works on Che- Auguftinaearth, 

 iniftry, both original and tranflations, fuch as Thompfon, 

 Aecum, Mur.ay, Henry, Parkinfon, La Grange, Green, 

 Fourcroy, Jacquin, &c. but in none of thefe authors is men- 

 tioned the method for obtaining the new earth, called Au- 

 gufiine ; altiioiigii moft of thefe works have been publiflied a 

 confiderable time after this earth was made known by the 

 German difcoverer, I^.ofeffor Tromfdorf. I have alfo made 

 enquiry, concerning this fubjed, of moft of the public teachers

 one of your Correfpondents will be kind enough to favour me 

 with the procefs for obtaining this earth ; for the author of 

 thefe lines cannot find it in the mineral which is faid to con- 

 tain it ; having purfued the ufual methods of examining mi- 

 neral fubftances for that purpofe.
