On the Affinities of different Earths for Car I on. 33 ^ 



M. Laxman concludes his journal with the following 

 translation of the paper transmitted to him by the Japanese 

 government : 



" We permit one Russian ship to enter the harbour of 

 Nangasaki ; but we at the same time renew the prohibition 

 that no foreign ships can be admitted into any other part of 

 our kingdom, and that neither the Christian religion, nor 

 iny signs of it, can be allowed. We desire also, that in all 

 transactions nothing may be done contrary to the laws of 

 our empire, and that the regulations which we have esta- 

 blished shall be strictly observed. For this purpose the pre- 

 sent writing has been delivered to M. Adam Laxman. 

 Done in the town of Matmai." 



LV. Experiments to ascertain whether there exists any 

 Affinity betwixt Carbon and Clay, Lime and Silex, se- 

 parately or as Compounds united with the Oxide of Iron 

 forming Iron Ores and Iron Stones. By David Mushet, 

 Esq. of the Calder Iron-Works. 



[Continued from p. 282.] 



XjLaving rigidly ascertained the metallic properties of the 

 oxide of iron which was to enter into the composition of 

 several artificial mixtures, I next proceeded to reduce it to 

 a very fine powder and mix it with different earths. 



First Class 



Consisted of 6 parts of well dried Sturbridge clay, 



4 of oxide. 



Exp. I. 500 grains of this mixture, 



12^., or l-40th of carbon, were fused together. 

 A minute spherule of malleable iron was obtained which 

 weighed 14 grains, equal to 2-^ths per cent, from the mix- 

 ture. 



The glass was dark and rough, excepting where it ap- 

 proached the neighbourhood of the metallic mass. 

 II. 500 grains of mixture, 



25 of carbon, or l-20th. 



These were intimately mixed and fused. A neat button 

 of metal was obtained which weighed 46 grains, and equ*l 

 to O-f.jths per cent. The glass in this experiment. \vas mate- 

 rially altered : the additional dose of carbon and the revival 

 of a greater portion of metal left the glass of a fine black 

 shining colour,, possessed of a Beautiful lustre where it sur- 

 rounded
