I offer this as a probable explanation of the immediate or almost immediate disposition to sleep. As to the permanent improvement in sleep, where this has been below the normal standard, it must always be due to the removal of some morbid condition, and thus belongs among therapeutic results, rather than physiological effects. It is true that in many instances of agrypnia we are unable to discover any pathological condition that would account for this symptom; but the probability is that here there is a sluggishness of some one or more of the functions, mental or physical, too obscurely manifested to be discovered by our present means of diagnosis, yet reached and rectified by a mode of electrization that traverses and permeates every portion of the body.
