A treatise on the diseases of the nervous system . dsection of the spinal cord taken from the cervical region of a woman,aged fifty years, who died in the Salpetriere, of general paralysis of theinsane, and in whom there was infantile spinal paralysis affecting theright superior extremity. The atrophy of the right anterior horn iswell marked, and the emaciation of the right antero-lateral and poste-rior columns, probably a secondary complication, is also notable. The atrophy and disappearance of the nerve-cells are sometimes ex-ceedingly limited. In the accompanying figure (Fig. 39), also from Char-cot, an enlarged view is given of a section of the spinal cord taken fromthe lumbar region in a case of infantile spinal paralysis, affecting theright lower extremity : A, the left anterior horn, healthy ; a, healthygroup of ganglion-cells ; J?,.right anterior horn ; b, median ganglionarynucleus, of which the cells are destroyed, and which is represented by afoyer of sclerosis. In Fig. 40, a still more enlarged view is given of the Fig. right anterior horn : a, cervix of the posterior horn ; b, postero-externalgroup of nerve-cells ; c, antero-external group, the cells of which haveentirely disappeared, while they are intact in groups b and d; d, inter-nal group ; e, the commissure. The myelitis is parenchymatous in character^ that is, it begins in the INFANTILE SPINAL PARALYSIS. 475 nerve-cell structure, and, if the neuroglia be found involved, it is fromthe extension of the morbid process, and not from any primary implica-tion. This is sufficiently established, not only from an examination ofsections of the cord, such as that represented in the last figure in whichthe lesion is restricted to the nervous elements, but from a considerationof the physiological relation which exists between the cells of theanterior horn and the functions which they have to perform—func-tions which are interfered with in cases of infantile spinal paralysis.
