The Book of Prognostics
Hippocrates says, "It appears to me a most excellent thing for the physician to cultivate Prognosis..." This book is about his understanding of prognosis.
Prognosis is an epidemiological term defined as the relative probabilities of the various outcomes of the natural history of a disease and can be made about any outcome of an illness. It seems to be highly desirable that a physician should pay much attention to prognosis. If he is able to tell his patients when he visits them not only about their past and present symptoms, but also tell them what is going to happen, as well as to fill in the details they have omitted, he will increase his reputation as a medical practitioner and people will have no qualms in putting themselves under his care.
Respecting the movement of the hands I have these observations to make: When in acute fevers, pneumonia, phrenitis, or headache, the hands are waved before the face, hunting through empty space, as if gathering bits of straw, picking the nap from the coverlet, or tearing chaff from the wall- all such symptoms are bad and deadly.
