CHAP. CCCXCIII. Of the Exchanges of
Placentia with Valentia.
* 1.1PLacentia doth exchange with
Valentia, and is found to give one Crown of Mark, to have in Valentia 23⅓ Sols posito: I demand, for
Crowns 926. 19. 2 of Mark, how many Livers shall I have in Valentia? To do this, multiply the said sum of
Crowns by Lavers 1, 3, 4 d. per Crown, which are the said 23⅓ Sols, beginning the multiplication by the
Deniers, and then by the Sols which are with the
Crowns, and they will make Livers 848. 2. 4 d. And so much shall Placentia have Credit in Valentia. Example: 〈 math 〉〈 math 〉
* 1.2Note, That when Placentia doth exchange with Barselona and
Saragosa, the account thereof is made up, as the above-mentioned exchange from Placentia to Valentia.* 1.3And the proof of the said Rule is apparent, when that Valentia shall exchange back for Placentia.
