Dative:—[Greek: ——]
Thuc.VIII. 24. This is the Latin usage.

Accusative.—I do not remember an instance of the proper accusative absolute in Thucydides; but it seems not uncommon in other authors: [Greek: ——]

Yet all such instances may be nominatives; for I cannot find an example of the accusative absolute in the masculine or feminine gender, where the difference of inflexion would show the case.—ED.]

The inflections of the tenses of a verb are formed by adjuncts of the verb substantive. In Greek it is obvious. The E is the prefix significative of a past time.

[Footnote 2: Nominative absolute:—[Greek: theon de phozos ae anthropon nomos, oudeis apeirge, to men krinontes en homoio kai sezein kai mae—ton de hamartaematon.]—Thuc. II. 53.]

MAGNETISM.—ELECTRICITY.—GALVANISM.

Perhaps the attribution or analogy may seem fanciful at first sight, but I am in the habit of realizing to myself Magnetism as length; Electricity as breadth or surface; and Galvanism as depth.
