in thinking of scolding me." Morgagni.--In the century following Sydenham we have a number of examples cited by Morgagni, the father of pathology, in which his recognition of the value of the mind as a curative agent and of the harm that may be done by over-occupation of the mind is set forth at its proper value. Benjamin Ward Richardson in his "Disciples of AEsculapius" [Footnote 2] tells of two incidents in which this phase of Morgagni's very practical application of knowledge to medical practice is exemplified: [Footnote 2: London, 1901] {17} In other examples, where the symptoms are due to mental oppression, he pursued a course of treatment that was of soothing nature. A distinguished professor of physic at Bologna happened to discover that his pulse was intermittent, and being extremely anxious about it was incessantly feeling his pulse, to discover that the evil was daily increasing. Morgagni's advice to his patient was to take his finger off his wrist and not to inquire too anxiously about his condition. The advice was followed, and the result was a complete removal of the disturbance. It is a very singular truth that in describing the action of the nervous system on the circulation Morgagni shows that he was cognizant of the fact that the circulation may be disturbed by two sets of nervous irritations, one inflicted through the pneumogastrics, the other "through those nerves which are subservient to the arteries"--the vaso-motor system which is readily disturbed by the mind. In one patient he observed great perturbations of the pulse in both wrists as the result of mental anxiety. But a day or two later the pulse derangement was confined to the left side altogether. The pulse of the right arm was quite regular, while that of the left arm still showed the inequality. When the mental distress was relieved, this pulse also became equal. Morgagni cites Sydenham's contemporary, Lancisi, the great Italian physician, as recognizing the influence of the emotions on the heart. Examples of similar convictions as to mental influence in medicine are also found in the works of Morgagni's great contemporaries, Boerhaave and Van Swieten, and the great physicians of the seventeenth and eighteenth centuries were closely imitated in their recognition of the value of the influence of mind over body in medicine by their successors in the profession.
