Editor's Notes

p. 3-7 "The rotation of the earth around the sun (which is an immense magnet or spherical mass with polarity one 1/2 N other half S Throwing out lines of force through space) cuts these lines of force so one side of the earth is N the other S but this does not produce a current but the rotation of the earth on its axis causes the circulation of a tremendous current around the earth in direction and parallel with the Equator clear up to the two poles which it creates. The mutual attraction of the lines of force of the Earth with its poles and the lines of force of the sun is at the present distance of the Earth from the sun just sufficient to balance the tendency of the earth to go in a straight line, hence its orbit-- The lines of force eminating from the sun are eleptic as produced by the counter lines of force from bodies outside of our planetary system, hence the earth to always be in an exact balance between its tendency to proceed in a straight line & the attraction of the sun must move in this eleptic orbit-- The rotation of the earth to produce the seasons must be due to the feact that the sun oscillates in the same manner-- Expmt To ascertain the strength of electric polarization of matter on earth subject to conduction & in current form Take two wires each 500 feet mile long one east & west the other north and south, No 0000. Sink a several large porous pot at one end in good damp earth fill with solution of Sulphate Zinc & use amalagmated electrode zinc for ground plate-- measure daily morning noon & night current & volts on both wires (drawing)"
