on the subject by Sir T. Dick Lauder, Bart. FIISE. in which he states, 

 on the authority of a friend employed for many years in the trade 

 between China and India, " that the substance analyzed by Dr. Fyfe 

 is not tutenag, but white copper, the properties of which are totally 

 different; " and he then proceeds as follows : 



" The white copper is used by the Chinese themselves, who are so 

 jealous of permitting other nations to have it, that its exportation is 

 contraband. In defiance of this, however, considerable quantities of it 

 are smuggled out of the country, and introduced into India, where it is 

 considered as a great present to the Hindoos, &c. who make domestic 

 vessels of it. The tutenag, on the contrary, is an article of very 

 extensive commerce between China and India ; and my friend informs 

 me, that it is sent from China in slabs, of which he has had occasion to 

 buy and sell many thousands. The slabs are about eight or nine inches 

 long, by about five and a half wide, and about five-eighths thick. Its 

 colour is greyish; and it is not malleable, but so brittle that it is even 

 necessary to use considerable caution in putting it on ship-board, to 

 prevent its being broken by one piece striking against another. The 

 fracture has a glittering lustre, and somewhat resembles the appear- 

 ance exhibited by that of bad iron; but the crystallization (if such a 

 term may be employed) is larger. It does not ring, but emits a heavy 

 clattering sound. It is employed by the natives of India as an alloy 

 for copper, to make brass for their domestic utensils."
