The Herb Pantagruelion hath a little Root somewhat hard and ruff, roundish, terminating in an obtuse and very blunt Point, and having some of its Veins, Strings or Filaments coloured with some spots of white, […]

If you put foure Spleets in a Hiue, then cut their backes, where they must leane one against another, to square angles, such as be foure in a circle: if but three, cut them to obtuse angles, such as are three in a circle: (you may readily try them, before you put them in, by Moulds made iust to those formes) and so will they stand close and firme together.

Unless A lies in that part of a semi-infinite strip bounded by AB outside a semi-circle of diameter AB, the triangle is obtuse, so that the probability of getting an obtuse triangle is equal to 1.

It was a merry time with Carrmen, Watermen, & Porters: for in this Eclipſe, many of them did nothing but drinke, domineere, and ſwagger in Alehouſes; but the often going to and fro of the Pot, made them talke of that, which they had nothing to doe withall, and many times their obtuſe apprehenſions would be medling with the warres betwixt the great Turke and Preſter Iohn, how it was likely to end; […]
