Here's a book that spans two markets, -- the layman and rank amateur among adults, who would like to short cut to better understanding of the subject; and the boy who is dabbling in electricity. An anecdotal history of electricity, based on the Christmas week lectures at the Franklin Institute in Philadelphia. From the beginnings of electric experimentation, through Benjamin Franklin, on to the latest experiments with the phenomena of cosmic rays. Pictures and diagrams, descriptions of special types of apparatus, etc., help clarify the whole. One gets a sense of the growth of ideas as well as the basic facts of discoveries. A good primer of science.
