Depth of rhomb 18/200 = 9/100

[anth] num 17/200 = 85/100

[anth] & better number 26 or 27/200 = .13

Erasmus says by calculation .088 say nearly .9/100

(Thickness of side about was about 1/20 = 5/100)

Measurement of Depth of Rhomb —

Depth of Basin 10/200 = 5/100 = .05

in spec. n^r 8

as near as can be measured

Growing edges of hexagon in quite grey count 4-6 1/2 /200

say 5/200: as prism size edges [are only] 2-3/200

[barq] = .05

Depth of rhomb 18/200... 1/20 = 5/100)] in pencil. This document is written on blue ribbed paper.
