Note 1 — Chapter I
John Ingram Lockhart translation
During the first conquests of the Spaniards in New Spain, one half of the profits arising from the gold mines was paid to the crown; but the ill effects of this exorbitant demand soon began to show themselves, and it was reduced to one third, and then to a fifth, called the real quinto, which continued for a length of time, until it was further reduced. I must take this opportunity of observing, that the Spanish "peso" is equal to about 4s. 6d. of our money. (p. 3.)
