intellect, by which it has been ascertained that certain ones of the
millions of nerve corpuscles or fibres in the grey substance in the
brain, record certain classes of sensations and the ideas directly
connected with them, other classes of sensations with the corresponding
ideas being elsewhere recorded by other groups of corpuscles. These
corpuscles of the grey matter, these mysterious and infinitesimal
hieroglyphics, constitute the memory of the record of the life, so that
when any particular fibre or group of fibres is destroyed certain
