per cent.; by the succeeding proclamations of 30th April 1636 and 7th September 1641 this limit was raised respectively to 25 per cent, and 50 per cent.
Philip IV. also instituted the first change in the silver system which it underwent since the great reform of 1497.
The tale was increased from 67 to 83 3⁄4 per mark, the real of eight being henceforth issued at an equivalence of 10 reals.
This change was equivalent to a reduction of 25 per cent. in the silver monies.
Under Charles II. this corruption proceeded in an ascending scale until 1680, when the gold doblon had arrived at an equivalence of 110 reals of billon, and the real of eight to 29 reals of billon. Page 330
