☞ The names sciences ending in ics, as mathematics, mechanics, metaphysics, optics, etc., are, with respect to their form, nouns in the plural number.

Previously to the present century, nouns ending in ics were construed with a verb or a pronoun in the plural; but it is now generally considered preferable to treat them as singular.
