general prices occurs, but it is no longer, as before, on level lines of the two metals equally. The proportion of the production of the two metals changes, so rich was the yield of the silver mines of Potosi. From being the same with that of gold, the value of silver produced suddenly rises to three times and then to four times that of its rival; and at once the ratio changes, bringing with it all its accompaniment of feverish instability and flux.
The average result in the ratio was as follows:—
| 1545-60 | 11.30 |
|---|---|
| 1561-80 | 11.50 |
| 1581-1600 | 11.80 |
| 1601-20 | 12.25 |
