Analysis

• What elements do the texts quantify?• What are the differences between the texts?• How does this quantification compare to

contemporary quantification?

Sylva

• “In other places, the cord is four feet in height; and four feet over; or, to speak more geometrically, a solid made up of three dimensions, four feet high, four feet broad, and eight feet long; the content one hundred and twenty-eight cubic feet.”

• “But by none, in my apprehension, set forth in a more facile and accurate way, than what that industrious mathematician, Mr. Leybourn, has published, in his late Line of Proportion made Easy, and others his labours.”

French Forest Ordinance

• If there be found any encroachment or extension beyond the pieds corniers, the merchant shall be condemned to pay fourfold the rate of the highest sum of his bidding, in case that the wood cut by him shall be of the same kind of tree as that of the purchase; and if it be of a better kind, quality, or age, he shall be bound to pay that penalty, and to make restitution au pieds le tour. (XVI.9)

• For example, this does not consider :1. Quantification in husbandry directions2. Quantification of time, either seasonal or

years3. Enumeration of the number of individuals

who filled certain roles4. The use of lists5. The use of numerals

I am obliged to include another image of Porter’s book because we have not seen enough of it this semester
