    Page CHAPTER XV. INFLUENCE OP HEAT IN CONNECTION WITH MALARIA. Effects produced by continued exposure to a very high temperature-Hum- boldt’s observations—Remarks of Sir J. R. Martin, and Dr. Morehead— Malarious fevers always most prevalent after great heat-Pringle’s and Pergus- son’s observations—Effects of insufficient protection from calorific influences— Pringle’s remarks—Author’s experience—McKinnon’s observation—Cause of unhealthiness of casemated barracks and forts in India—Effects of exposure to sun—Remarks of Drs. Dick and Murchison—Chill a cause of malarious fevers during great heat and drought—Explanation—Type of malarious fevers aggravated in hot season—Ferguson’s remarks—Fevers more severe after unusually protracted heat, and most malignant in hottest climates— Some forms of fever caused by heat—Dr. B. W. Richardson’s remarks—This class of diseases not considered malarious—Tet most intimately connected with remittent and intermittent fevers—Disorders considered to be result of climatic influences, scarcely distinguishable from others, supposed to be caused by a specific poison—Dr. McKinnon’s remark—Connection between ardent and malarious fevers explained 124 CHAPTER XVI. EFFECTS OP EXPOSURE TO CLIMATIC VICISSITUDES. Those most exposed to sudden changes of temperature suffer most from malarious fevers—Pringle’s observations—Private soldiers suffer more than officers and latter more than civilians—Each class attacked by same dis- ■eases—Many attempts to explain this difference but none of them satisfac- tory—Alcohol is not malaria—Drunkenness often leads to exposure to climatic influences—When this is avoided drunkards scarcely more liable to fever than sober men—Cases in point—Exposure on night duty great cause of sickness amongst soldiers—Observations of Messrs. Snell, Hensman and Morgan, and Drs. Davy and Murchison—Also of Sir J. Pringle and Mr! Hennen—Mr. Gore, on fever at Sierra Leone—Dr. Livingstone’s experience —Cases of malarious fever from exposure on board ship—Effects of exposure to rain in tropics—Mr. Hare’s observations—Lind’s and Humboldt’s remarks Native servants in India often suffer from fevers during cold and wet weather, when their white employers escape—In some cases those exposed to climatic vicissitudes attacked by fever, whRe others not so exposed escape —Instances CHAPTER XVII. BOTH PRIMARY AND RECURRENT ATTACKS OP MALARIOUS FEVER RESULT PROM SUDDEN CHANGE PROM HEAT TO COLD. Paroxysmal fever often makes its appearance upon a sudden change from a hot to a colder climate-EspeciaUy if effect, of change be heightened by expo- Bure to wet or a cold wind—This effect produ ced even when the change is to amost healthy locality—Persons in India attacked with fever for first time on arrival
