TH. FINDLATER ZANGGER.—The author calls attention to the strain on the heart and arteries at elevations of three and four thousand feet and above, and especially of rapid ascents. Mountain railways are in this way dangerous to an unsuspecting public. The bad results in these cases, heart collapse, angina pectoris, cardiac asthma and apoplexy, often only appear after the return to the lowlands, and patients with cirrhotic kidneys are in greatest danger. In case of apoplexy, it is generally the combined influence of a few things slight in themselves, that, added to the altitude, produce the worst results. Over-feeding, over-exertion, exposure to hot sun, bowel neglect all have their part. Zangger advises an almost vegetarian diet in arteriosclerosis, with use of mineral waters, caution as to stimulants and avoidance of exercise in the heat of the day, especially in shut up valleys where the sun's rays are intensified in the rarified atmosphere.
