Not illustrated. 1871 Excerpt: ...facts which have been demonstrated thereby. The most positive assertions have been made concerning facts only to be demonstrated and understood by those who have made themselves It is very significant that no attempt is made by philosophers who discourse on the origin and destination of living beings and of the world they inhabit, to account for the wonderful arrangement of one of the very many textures of a living thing, and of the intimate relationship they bear to one another, or for their exquisite and orderly adaptation by which excellence of action and perfect fulfilment of the objects of their formation are ensured. A nerve centre is represented in Fig. i, pl. III. The little oval bodies embedded in it are the nerve cells, from each of which two or more delicate nerve fibres extend, or have been drawn out during the growth of the tissue. These nerve fibres run between contiguous cells and seem to surround them, as in the drawing. Formerly they were supposed to form a capsule of "connective tissue," in which it was said the nerve cells were embedded. The ' cells' are the sources of nerve force, which is, perhaps, closely allied to, but more probably identical with electricity. The currents starting from a cell traverse nerve fibres, which are often of great length, and, after being conducted along many fine fibres resulting from subdivision of the original nerve fibre, practically familiar with minute inquiry, by authorities who have been occupied in a totally distinct branch of scientific investigation, and who are quite ignorant of microscopical work. Microscopical observers have been told what they ought to have seen, and what they have seen has been condemned by 'philosophers' whose remarks prove them to be absolutely ignorant even of th...
