This is the first volume of the series "The Patient and the Weather," its publication having been delayed in order that certain meteorological data might be checked. Reviews of other volumes have already appeared in this journal. One volume had to do with the chemical and vascular changes which occur in the autonomically unstable person in response to sudden variations in meteorological conditions; another, with the incidence of certain types of disease in the storm tracks of the United States as compared with their incidence in other areas.
This volume has to do with the chemical and vascular response of normal persons to atmospheric changes. The studies were carried out in Chicago, where rapid shifts in temperature, humidity and barometric pressure occur. Of normal men, those of the pyknic type show the greatest stability, adjusting themselves readily to change. The leptosome responds with great swings, which are frequently associated with
