The functions of the different columns of the cord are only partlyknown. That the anterior and lateral pyramidal columns containthe motor fibres is certain, but as to exactly what nerve fibres passup in the different sensory columns is not yet established, althoughthere has been a vast amount of conjecture upon the subject. Theweight of evidence, however, such as it is, would seem to prove thatthe nerves of touch pass ventrad in the outer part of the posteriorhorn and the adjacent lateral column, whilst the nerves of pain andtemperature are contained in the Gowers columns. Before enteringinto this subject let us consider briefly the gray matter of the spinalcord. This is disposed, as represented in Fig. 37, in the form ofhorns. The anterior or motor
