It has been said by some astute critic that “insanity has no pathology,” but it would be a nearer approach to scientific truth if he had said that, with our present imperfect means of investigation, there are many cases of insanity in which no pathological changes can be discovered as the cause of the mental phenomena. The microscope, for example, has as yet failed to differentiate the delicate alterations in the protoplasm of the cerebral cells which result in an outburst of maniacal excitement; nevertheless, the ophthalmoscope shows changes in the vascular supply of the brain in many such cases, and, with the aid of the sphygmograph, light has been thrown on many hitherto obscure conditions of the circulation.

Eulenburg and Guttman maintain that epilepsy in many cases owes its origin partly to a direct and partly to a reflex irritation of the vaso-motor nerves—the “angio-neurotic” theory.

In the “British Medical Journal,” 1874, p. 522, Dr. J. Crichton Browne records the treatment of two cases of general paralysis by the continuons administration of calabar bean. The first case was discharged “recovered” in less than a year; the second, a female, after three years' treatment. I am unable to say whether these were real recoveries or only remissions, as the ultimate history of the patients is not given. Several other supposed recoveries have been published, but in none is a complete life history recorded, and they may have been only remissions in the course of the disease.

In an interesting paper (“American Journal of Insanity,” July, 1886), Dr. H. M. Hurd discusses the relationship existing between syphilis and general analysis.
It follows also, although perhaps needless to formulate, that the opinion of those who have maintained the scientific importance of pulse-tracings in mental disorders is more than justified.
