    trunks emerging at the anterior and posterior sacral foramina. On a transverse section (Fig. 228, p. 496) the spinal cord will be found to consist of white nervous matter, in which are seen two gray crescents, with their convexities turned toward one anotlier and connected together by a gray commissure^ in front of which are some white fibres forming the white commissure. The anterior cornxia of the gray crescents are larger than the posterior cornua, but do not reach to the periphery of the cord; the slender posterior cornua are closel}^ con- nected with the posterior roots of the spinal nerves in the lateral fissure. A small central canal [canal of Stilling'] exists throughout the cord. It is impossible for the student in his ordinary dissection to investigate the minute anatom}' of the spinal cord, and he is therefore referred to works on minute anatomy for fuller details.
