CEREBRAL HYPERÆMIA: the Result of Mental Strain or Emotional Disturbances. 16mo, cloth ... $1 00

"Under the disguise of these hard words, Dr. Hammond presents a variety of admirable counsels, with regard to an excess of blood in the head, pointing out its causes, its symptoms, the mode of its medical treatment, and the means of its prevention."—N. Y. Tribune.

"The work is not only of interest to the medical man, but also is one easily understood and to be read with profit by brain-workers of all classes, whether in profession, in literature or business. It treats of the cause of headaches, the wakefulness, the illusions or delusions, and feelings of tightness in the head, which so many of our American writers and thinkers experience, and it gives valuable information available by laymen as to the prevention and remedy for this affection, which later on leads to insanity or death."—Boston Traveller.
