In a limited space I have sketched the state of Hank lin's mind in regard to the singular phenomenon of the existence of attracting or repelling charges of electricity and I have endeavored to show that the latest theory in electricity the electron theory closely resembles his theory of excess and deficit. While his philosophical views of the phenomena of electrical sparks are largely accepted, his experiments cannot be said to have led the way to practical employments of electricity. Their lack of influence on a great future development was due to a want of perception of the relations of magnetism to electricity. Hanklin's advance in his favorite subject was completely barred by an ignorance of these rela tions. I have quoted his words to show how feeble he considered the manifestations of magnetism in compari son with those of electricity. A giant was lying concealed in his workshop. All our great advance in electricity since the time of Hanklin has been due to the increase of our knowledge of magnetism. After we have con sidered the wonderful phenomena of radium we may be led to ask: are not the manifestations of magnetism still more wonderful?
