The authors studied the IIIIIINI I~ws~wc:: of a group of naval &ioers on board ship on West Indian waters. They .fuund that in the tropics systolic blood pressure of normal %vhite males varies 11) to 13 mm. mcrcuzy below the normal for the temperate zone. The change is not a rapid one aud rcsprcscnts a lower rasomotor tone and a general slowing of pllysiological activity. The routine of life must be modified to suit this alteration of physiological activity, if injury to the health is to be prcvcntc?d. This change is the mode of life including limiting regular pork to tlic cooler part of the day, avoiding cxcessive physical exertion, the adolltion of the siesta and observing precautions as to food and clothing. ‘I’hc I,lood pressure and basal metabolism being affected by t-l&ate, it is probable that variations in other physiological processes occur and should be investigated.

The authors have arranged a series of curves to show the seasonal variations in mortality from organic disease of the heart or from organic diseases of the heart, cerebral hem’orrhage or chronic nephritis combined in mean weekly temperatures and in mean weekly barometrical pressures. The data were derived from the records of the vital and weather statistics of Chicago for the period January, 1924 to April, 1936. The curves show that mortality was high when temperature was low There is no clear apparent correlation between fluctuations in and vice versa. mortality and in barometrical pressures. Variations in mortality from the specified causes are inversely c.orreIated to a very high degree with variations in temperature in the second and fourth, but not The results of this investigation suggest in the first and third quarter of the year. that patients who are especially exposed to the lethol effects of organic diseases of the heart, cerebral hemorrhage and the chronic nephritis should be warned of the unusual danger attendant on cold weather.

A group of 77 aault patients with advanced congestive heart failure were treated with digitalis and diuretics of the santhein group. TheophylIin, theobromin and t,heobromin sodiosalicylate. Thirty-six were made edema free by digitalis alone; 13, of the remaining 41, were entirely relieved of edema by one or more of the diuretics employed; 5 others had well marked diuresis with loss of most of the edema and 5 were moderately benefited. Theobromin sodiosalicylate in doses 2.6 to 5.3 gm. daily for five to six consecutive days was effective in only 2 of 8 ,pationts. Although 5 of the remaining 6 responded satisfactorily to theobromin and theophyllin, it was regarded as of very little value. Theobromin in doses of 0.6 gm. three times a day for two days was partially or entirely satisfactory in 7 of li patients. Of the remaining 10, one-half later obtained excellent diuresis from theophyllin. Theobromin was a far more effective diuretic than was theobromin sodiosalicylate and was equally devoid of undesirable side actions. Theophyllin was far more potent of the three preparations. It proved effective in a nunlber of persons who had failed to show diuresis after the administration
