APPENDIX 



ELECTRICAL CONDITIONS OF THE EARTH 



The influence of electrified railways, tubes and tram-lines Earth 

 conditions during thunderstorms Earth and cloud in electrical 

 relation Lightning and its path through the atmosphere 

 How the body may be influenced The earth as zero The 

 earth electrically " patchy " The Rio Plata and mouths of 

 rivers Earthquakes and thunderstorms in the tropics No 

 definite knowledge of the causes which set up earth-currents 

 The aurora borealis Atmospheric electricity Fulminic matter 

 Thermal origin of earth-currents considered The distribution 

 of volcanoes Uncertainty as to their condition Earth-current 

 in the far North Dry or dielectric soils and their possible effect 

 upon the atmosphere and health, as compared with conductive 

 soils The torrid, temperate, and frigid zones Atmosphere as a 

 vitalising agent - 267 



ELECTRICITY IN RELATION TO SOME VEGETABLE POISONS
