X H E flcels which Citizen Vauqucliu has analyfed were fent to the Council of Mines 

 numbered S64J, 864*1 977 and 1034. Thefe fteels were produced at the forge of Retn- 

 nielfdorff, fituated in the canton of Grofs-Remmelfdorff, in the department of the Mofelle, 

 at the dlftancc of 5030 metres north from Bouzonvilie, and the left fide of the Nled. 

 The crude irons which are there refined come from the furnaces of Dilllng and Betting, 

 which, according to the report of Citizen Dietrich, obtain their iron (tone from the com- 

 munes of Grefaubach and Steinbaeh, as well as from the foreft of Hommelfwald ; and their 

 calcareous flux (caftine) ftom the woods of the commune of Merfching. The cftablifli- 

 ment confills of two fineries, one large hammer, two fmaller, and a heating furnace. Citizen 

 SoUer, the proprietor, had eftabliflied before 1785 a manufactory of fteel by cementation, 

 which, after having been abandoned for feveral years, has again been put into aCtivity. 

 The cementing furnace contains, according to the account furniftied by this citizen him- 

 felf to the Council of Mines, about fix thoufand weight of iron, and can be charged two or 

 three times a month. 



Citizen Dietrich, who vifited this eflabliflmient in 1785 by order of Government, infpe£led 

 the procefs, and the furnace of Citizen Soller, of which he gave the mod advantageous 

 account. By this report it is feen that Citizen Soller ufes coak for cementation f. Wc 

 think, it may be of advantage to tranfcribe in this place the report which was made on thcfe 

 fame fteels in 1786, by the Commiflaries of the Academy of Sciences. It is thus by com- 

 paring the refults of operations performed in manufaiElories under the infpe£lion of learned 

 men, with th^fe afforded by the chemical analyfis, that we may hope to learn to what extent 

 the nature and proportion of the conftituent parts may influence the qualities of fteel ; 

 and whether we may expecl from chemical fcience new and dire£t methods of afcertaining 

 what kinds are beft appropriated to the different ufes of this fubllance in the arts.- 



Extrctcl from the Regillers of the Academy of Sciences, March 15, 1786. 



ON the 15th of February laft, Mr. Soller prefented fome fteel of cementation from his 

 works at Remmelfdorfl^, in Lorraine, near Saar-Louis. The Academy has charged Mr. 

 Vander Monde and myfelf to give an account of the fame. 



We muft diftinguifh three kinds of fteel, each of which poflefles properties relative lo 

 the different ufes they are applied to. 



I. Natural fteel (acier dc fonte) is obtained immediately from the crude iron. This fteel 

 is ufually unequal in its quality; fubjecl to have cracks and fcales ; is lefs hard and 

 brittle than the two other kinds ; welds better, and is principally ufed for inftruments of
