 rWid adherents to thefe names, and to the modes of thinkins: 

 afibciated with them, would fcarcclv have patience enough 

 to Hften to any modernifed, or, as they would term it, new- 

 fangled ftatement of the facls. This difficulty was the more 

 formidable, as it was found neceflary eventually to make an 

 innovation upon the French nomenclature itfelf. 



To facilitate his own conceptions of things, rather than to 

 affeft novelty or attraft profelytes, and alfo to render his ex- 

 preflions of thefe things more correct and eafy, he propofed 

 w'hat he deemed an allowable amendment to the nomencla- 

 ture, by expung'mg azote, azotic, jiitrous, nitric and their 

 denvatlves, and takingy<:/)/ow for the radical term, with fep- 

 Jous, feptic, &c. as the preferable ppithets. He eonceivecj 

 he had a right to make ufe of a nomenclature of his own, if 

 he pleafed ; while others, if they preferred it, were at liberty 

 to adhere to the old one.

 Iron JVorks. Comvumicatcd hji the Author, 



JL HE tenacious lava wiiich is formed when iron ores or 

 iron ftones are fufcd without the addition of any other fub- 

 llance, firft led to the api)licalion of calcareous earths, in 

 various proportions ; that a fluid fufficicnth- thin and divided 

 might be formed, and the iron difengaged from its vitrid 

 connexions, precipitated to the bottom of the furnace. If 

 the nature and mixture of the ore are well underfiood, the 

 quantity of lime neccflarv to reftore a juft equilibrium of pro- 

 portion in the lava will be rc;idily attained ; the metal, no 

 longer incorporated with or fufpendcd in the mafs, will be- 

 come completely revived, and flow from the furnace fuffi- 

 fiiently purified from its earthy mixtures.
