Method of manufacturing it into Cloth 

 or Paper, which would for a conliderable 

 Time remain unconfumed in a common 

 Fire : it is found either enclofed in other 

 Stones, or on the Surfaces of them. It 

 has been fuppofed that this Kind of Cloth 

 was made Ufe of among the RGjuans at 

 their Funerals, to preferve the Alhes of 

 the Deceafed unmixed, in order to their 

 being depofited in the Urn. On fome 

 late Experiments made, a Napkin of this 

 Cloth has been found to fuffer a very fen- 

 fible Diminution of its Weight every 

 Time it was put into the Fire. Dodlor 

 Hill with Reafon thinks that a Stone of 

 this Kind, which he defcribes as white, 

 loofe and thready, Vv^ith broad Filaments, 

 never forming themfelves into Maffes, but 

 always remaining loofe, might be manu- 

 fadtured into Cloth of the Kind above- 

 mentioned. It is found near the Surface 

 of the Earth in many parts of Scotland, 



Under the Title Sulphura are compre- 

 hended all the inflammable Minerals.
