tion given by Lodge, of a uniform charge in motion. He says, 

 "While the charge is moving at constant speed (growth would 

 represent the same force of accumulation of charges) the current 

 is steady, and we have a steady magnetic field superposed upon a 

 steadily moving electric field," etc. Electric lines of force are 

 straight lines, and we see the lines radiating from a centre, and the 

 curved and circular rings growing upon the straight lines. 



In Figure (8) we have the picture of the first forms of sponge 

 growths, and we find the same directions in formation of lines 

 as " magnetic lines of force which form at right angles to those 

 of the electrostatic lines. In the sponges we have the three differ- 

 ent directions in which the spinal nerves are found in the human 

 body, as transverse, oblique, and vertical. The lines of growth 

 on these sponges show their protoplasmic origin as " seafoam " or in 

 bubbles as a water-cell filled with gas crystallized into lines as 

 " fibrilla, and a network." 



PLATE 4 



This plate shows specimens of growth characteristic of Eozoon 

 Canadense, bacteria (17) and a formation of iron ore, sawn 

 through the piece of rock (18). Number (9) is bacterial growth 

 forming at right angles along a vertical line. Number (10) a 

 growth of Eozoon, showing the same direction of growth. Figures 

 (5) and (6) show growths of Archaeospherina and a bacterial 

 formation. Numbers (10) and (16) are forms of growth of bac- 

 teria and Eozoon. Figures (14) and (15) are Eozoon and bacteria, 

 but turning in an opposite direction. (11) and (12) are pictures 

 of bacteria and Eozoon. Figures (7) and (8) are a colony of 

 bacteria (after staining) and a specimen of Eozoon. The direc- 

 tions in which the rod-shaped cells lie in the bacteria colony only 

 show a definite arrangement, and a definite number in each direc- 

 tion. The influence of the staining agent would interfere with a 

 grouping in primal groups in a steady succession, but they would 

 group according to chemical combinations resulting from union 

 with the substance used in staining. The cells are " pushed " in 

 definite positions, because the stain could only enter through the pri- 

 mal or single field of gaseous electricity. The part of a bacteria colony 

 that will not take the stain is in the " magnetic " field, because it is 

 already occupying its position as a balanced filling of space. 



The resemblance between Eozoon and bacteria must be explained 

 in the laws of growth beginning at the point of decomposition of 

 parts into primal groups. The external must show this primal 

 marking.
