tained by a furnace : — -that used in these last experiments, was a 

 blast furnace, supplied by a constant and powerful stream of air ; 

 the fuel good Staftbrdshire coke, with a little charcoal ; both 

 Hessian and Cornish crucibles were used, one being carefully 

 luted into another, — and even three have been united, but 

 they could not be made to stand the intense heat. 



Meteoric iron, is, by analysis, always found to contain nickel. 

 The proportions are various, in the specimens that have been 

 chemically examined. The iron from the Arctic regions was 

 found to contain three per cent only of nickel, (see Journal, \o\. 

 VI, p. 369,) while that from Siberia gave nearly 10 per cent. 

 With the analysis of this last we are favoured by J. G. Children, 

 Esq., aaid, having permission from that gentleman, we most 

 willingly insert the account of his very accurate process. 



37 grains of Siberian meteoric iron gave 48.27 grains of per- 

 oxide of iron, and 4.52 grains of oxide of nickel. Supposing 

 the equivalent number for nickel to be 28, these quantities aje 

 equal to Iron 33.69 



Nickel 3.56 



100.00 

 A second experiment on 47 grains, gave 61 grains of per- 

 oxide of iron=:42. 57 iron. The amnioniacal solution of nickel 

 was lost by an accident; reckoning from the iron, the quan- 

 tities per cent are, Iron 90.57 

 Nickel 9.42

 A third experiment on 56 grains, gave 73.06 grains peroxidL-
