Effect Of Heat

No one can teil how high a temperatnre man can endure until he is subjected to the triaL The effect of an intensely heated atmosphere in cansina death has been but little studied. "Some years since, " says Dr. Taylor, the eminent jurisprndent, "I was coneqlted in one case in which the captain of a steam vessel was charged with manslaughter for causing a man to be lashed within a short distance of the stokehole of thefurnace. Themandied in a few hours, apparently from the effects of his exposure. Yet the engine rooms of steainers in the tropios have been observed to have a temperature as high as 140, and engineers after a time become habituated to this excessive heat without appearing to suffer materially in health. In certain manufactories the body appears to acquire a power by habit of resisting these high temperatures. Still, it has been proved that many suffer severely. "In a report on the employment of children (London) it is stated that in a glass manufactory a thermometer held close to a boy's head stood at 130 degrees, and as the inspector stood near to observe the instrument his hat actually melted out of shape. Auother boy had his hair singed by the heat and said that his clothes were sometimes siuged, too, while a third worked in a temperature no less than 150 degrees. Amid this treruendous heat they carry on work whioii requires their constant attention. They are incessautly in motion. " In the Turkish baths higher temperatures than this have been noted, but there is reason to beiieve that serious syrnptoms have been occasionally produced in persons unaccustonied to them, and that in one or two cases death has resulted. All sudden changes from a low to a high temperature are liable to cause death iu aged persons or iu those who are suffering from organic diseases. In attempting to breathe air 'heated to temperatures varying from 180 to 200 degrees there is a sense of suffocation, with a feeling of dizziness and other symptoms iudicative of an effect on the brain, and the circulation is enormously quickened. An iuquest was held on the body of a stoker of an oceau steamship. He had been by trade a grocer and was not accustomed to excessive heat. While occupied before the engiue furnace he was observed to f all suddenly on the floor in a state of insensibility. When carried on deck, it was found he was dead. All that was discovered on a postmortem examination was an effusion of serum into the ventricles of the bram. It has now become one of the recognized causes of death in this country. In some cases a person inay si uk and die from exhaustion or symptoms of cprebral disturbance may continue foi sonïs time and the case nltimately prove fatal. Death from sunstroke, when it is not immediately fatal, is preceded by some ■well marked symptoms, such as weakness, giddiness, headache, disturbed visión, flushing of the face, followed by oppression and difficulty of breathing, and in some cases stupor, passing into profound coma. The skin is dry and hot, and the heat of the body is ïnuch greater than natural. Walk slowly and don 't fret, and you will not experience anything of that
