Homo proponit, et Deus disponit,

Vol. ii. p. 427., ll. 13984-95. Ed. London: W. Pickering, 1842.

In the same way the author frequently introduces Latin texts from the Bible, and other books of authority and devotion. In the notes the editor generally refers to the place from whence the quotation is taken; but as there is no reference in connexion with the present passage, I infer that he was not aware of its source.

Polarised Light (Vol. viii., p. 409.).—I am unable to furnish H. C. K. with knowledge from the fountain-head touching this phenomenon. On referring, however, to a little work, much valued in my boyish days, I find it thus mentioned:

"The blue light of the sky is completely polarised at an angle of seventy-four degrees from the sun, in a plane passing through the sun's centre."—P. 219. Newtonian Philosophy, by Tom Telescope: Tegg, Lond. 1838.

Surely the Herschels mention this.
