1. On an Apprehended Depreciation of Money, arising from 
New Supplies of Gold. By Patrick James Stirling, F.B.S.E. 
The annual production of gold, in Europe, America, and Northern 
Asia, at the beginning of the present century, which was estimated 
by Baron Humboldt in round numbers at something over two and a 
half millions sterling, continued at about the same rate until additions 
began to be received from the renewed working of the Bussian mines. 
These additions, which, for the period intervening between 1810 
and 1822, are estimated by M. Michel Chevalier not to have ex- 
ceeded in all one million and a half, gradually increased, until in 
1847 they amounted to upwards of four millions per annum.
