IMroKTANr TO THE POOR
Apropos OF the Generals experiments, German
scientist remarked hat the discovery Of this extra
ordinary influence destined TO produce tho most
important and beneficial results tho comfort and

most Indispensable elements oil social and domestic
economy that u is. particularly in EUROPE very
