We find marked in the mental sphere a DROWSINESS OF MIND and CONFUSION OF THOUGHT, DULNESS OF INTELLIGENCE, a DAZED feeling of the mind. The party wants to think and not move, so absorbed in thought as to forget all else and where she is. There is a _complete listlessness and apathy_ of the mind; she cannot _concentrate_ her thoughts. From this want of concentration there follows an impairment of the memory, _she cannot remember what is said_. In conversation she will forget the subject, will begin a new one, and then suddenly change to another. There is great _confusion of ideas_. This listlessness is so great as to cause forgetfulness of what one is reading, or that one is reading at all: the book drops in vague and listless thought. The time passes too slowly, and minutes seem like hours. There is great irritability of temper. There is a continuous and ever-present feeling of heaviness of the head. PAINS IN THE LEFT SIDE OF THE HEAD and _over the left eye_, extending round the left side to the back of the head and neck, greatly aggravated by moving or jarring. Intense pain driving her to bed; relieved by sleep, but soon returning after waking. There is a constant dull headache, chiefly centered over the left eye and in the left temple; always worse in the dark and when lying down. Here we have a contradictory symptom--always worse lying down. The general symptoms are ameliorated by lying down. This peculiar feature is also seen in some of the polycrests. _Bryonia alb._ has a "pain and pressure in the shoulder when at rest." _Rhus tox._ has a "stiff neck, with painful tension when moving;" _Arsenicum alb._ has a headache relieved by cold water. _Onosmodium_ has a DULL, HEAVY PAIN IN THE occiput pressing upward WITH A DIZZY SENSATION. Pain changing from the right frontal eminence to the left and remaining there. Darting and throbbing in the left temple. A dull pain in the mastoid process. She cannot bear to move. A sense of fullness in the head. Relieved by eating and sleep. The eyes are HEAVY AND DULL; the eyes feel as though one had lost a great deal of sleep. The lids are heavy. The eyeballs have a _dull, heavy pain with soreness_. A sensation of the eyes being very wide open, with a desire to look at distinct objects, it being disagreeable to look at near objects. Distant objects look very large. _Picric acid_ patients can only see clearly at very close range, often at only five inches from the eye; _Natrum sulph._ has impairment of vision for distant objects. With _Onosmodium_ the ocular muscles feel tense, tired, and drawn. Pains in and over left eye. Pain in upper portion of left orbit, with a feeling of expansion. The vision is impaired and blurred. The hearing is impaired. There is a stuffed-full feeling in the ears as after catching cold. Singing in the ears as from quinine, but very slight.
