Another peculiarity is found in changes in the central nervoussystem. Thus poliomyelitic foci in the cells of the anterior cornua, de-generative condition of the posterior columns (see my case in , 1905), inflammation of the bulbar nuclei, have been observed.

Evidently the chemical poison which is the chief cause ofmultiple neuritis affects almost all parts of the nervous system but to adifferent extent in various cases: sometimes the peripheral nerves, motoror sensory or both, at another time the nerves and the cord. Etiology.—Intoxications are the most frequent causes. Alcohol oc-cupies the first place. Lead, mercury, arsenic, phosphorus, carbonicacid gas, intoxications of alimentary origin (ptomain) are also frequentcauses. Infectious diseases play a great role. Typhoid fever, diph-theria, small-pox, erysipelas, pneumonia, scarlet fever, grippe, dysenteryand tuberculosis are not infrequently accompanied or followed by multi-ple neuritis. In these cases the toxins are the immediate cause. In lep-rosy and beriberi the neuritis is due to a direct action of microorganism. Syphilis, malaria, diabetes, puerperal state, tobacc
