On the functions of the large sized cells, it seems desirable to add a few words as to the direction in which evidence as to their functions actually points. For this purpose, a further quotation is desirable, referring to the number of fibres or processes passing off from these large cells, distinguishing those which branch out into a fine net-work, and those which pass directly to a nerve fibre. "One at least of the processes of a multipolar nerve cell does not branch, but becomes directly continuous with a nerve fibre, and has been named the axial-cylinder process."--Professor Turner's _Human Anatomy_, i. 201. This taken with the facts given in Lecture VII, seems to favor the conclusions, (1) that the large cell spreads nerve energy through the tissue of the brain, while each has at least one direct line of communication with the system of nerve fibres; (2) that the large cell has intimate and extended relations with the motor system. XIII. THE CONCEPTION OF DUTY. _Page_ 273. "Duty! Thou great, thou exalted name! Wondrous thought that workest neither by fond insinuation, flattery, nor by any threat, but by merely holding up thy naked law in the soul, and so extorting for thyself always reverence, if not always obedience,--before whom all appetites are dumb, however secretly they rebel,--whence thy original?"--KANT'S _Critique of Practical Reason_. 530 BROADWAY, NEW YORK, OCTOBER, 1880.
