Note 7 — THE VISIBLE AND TANGIBLE.

Lewes' Biographical History of Philosophy. Vol. iv., p. 209. In every way a remarkable work. Written with great vivacity and clearness, comprising a world of matter in the briefest possible space,—and, O reader, and O author, forgive the anticlimax!—at the least possible cost. In fact it forms part of the Series known as "Knight's Weekly Volume." To find a strictly original work of so much ability given to the world in this form, proves that the publisher and the man of letters are, in this mercantile age, second to none in the activity and enterprise with which they render their service to the public.
