"Cuvier, in one of a series of lectures, delivered at Paris, in the spring of last year, says, "the name chemistry, itself, comes from the word _chim_, which was the ancient name of Egypt;" and he states that minerals were known to the Egyptians "not only by their external characters, but also by what we at the present day call their _chemical characters_.""
"Havelock Ellis  distinguishes, in addition to the primary and secondary sexual characters (as commonly defined), _tertiary sexual characters_, by which he denotes those differences between the sexes which do not attract our attention when we compare individual members of the two sexes, but which become noticeable when we compare the average male with the average female type."
"Such distinctive characters are spoken of as _secondary sexual characters_, in contradistinction to the _primary sexual characters_, the reproductive organs."
