This conclusion was, indeed, to some extent negatived by a deep indentation on the bridge of the nose, evidently produced by spectacles, and by marks which I looked for and found behind the ears, corresponding to the hooks or “curl sides” of the glasses. For those spectacles which are fitted with curl sides to hook over the ears are usually intended to be worn habitually, and this agreed with the indentation on the nose; which was deeper than would have been accounted for by the merely occasional use of spectacles for reading. But if only one eye was useful, a single eyeglass would have answered the purpose; not that there was any weight in this objection, for a single eyeglass worn constantly would be much less convenient than a pair of hook-sided spectacles.
