Relation of Climate to Health. 



The relatiou of climate to health and disease is attracting the 

 attention of scientific minds. Large numbers of statistics are 

 being collected for the purpose of discovering the exact bearing 

 that temperature, relative humidity and different electrical condi- 

 tions of the atmosphere have upon the health and mortality of the 

 people. That a direct relation exists, all who have investigated 

 the subject admit. Much time has been spent by this division in 

 collecting and comparing statistics, with a view of aiding in this 

 important undertaking. While the work has not progressed suffi- 

 ciently to warrant a lengthy article on the subject, still we deem it 

 proper to present at this time a few summary results. 



The curve of mortality has an inverse relation to temperature. 

 In some climates, however, the curve of mortality and tempera- 

 ture are directly related, rising and falling together. 



Fevers seem to be related to high temperature, and generally 

 follow it. 



The absolute humidity curve almost always follows that of 

 cholera infantum and cholera morbus. 



Pneumonia and diphtheria, small-pox, scarlet-fever and con- 

 sumption, invariably increase as the temperature falls. 



" La Grippe " is thought to be the direct result of natural atmos- 

 pheric conditions, chiefly a high followed by a sudden change to 

 low temperature. 



From careful observation it seems that there is a close connec- 

 tion between ozone at low temperature and deaths from pneumonia. 

 The ozone and cholera curves are inverse to each other, as also the 

 ozone and intermittent fever curves.
