[Commentary:
This page is part of Harriot's
experiments on refractive colours. Having calculated a 'good' cardinal on fols
187 ('E') and
186 ('F') to explain the secondary, colour-generating refraction in a glass prism, Harriot checks now that the refraction that it predicts does indeed concur with observation. ]
