Later on, when we have got the crises and the agrypnia by the throat, I should like you to take a little clear soup, and then a little broth, but always with milk; au lait!
Among the most prominent and annoying symptoms was _agrypnia_.
Although, as a rule, but the symptom of some definite pathological condition, agrypnia is of such frequent occurrence, and so detrimental to the general health, that it appears to me to merit special consideration.
_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.
