The list of Sir Oliver Lodge's writings is long and varied, ranging from school text-books in elementary science through The Ether of Space, School Reform, Life and Matter, Reason and Belief, to The Survival of Man. With most of these writings I have no direct acquaintance, but on the mere evidence of their titles one may with reasonable safety venture certain particulars toward an estimation of their author. He must have intellectual vigor, he must have an instinct for vital questions, he must have the power of popular exposition, and, finally, he cannot be overcautious in the formation and expression of his opinions. All of these particulars would, I believe, be found also in any consensus of judgment that his fellows in science might pass upon his scientific work. This, if not unmixed praise, is much to say for a man, and it may be added that in general he speaks out from a sense of well-being natural to one of cheerful and sturdy temper who has achieved fame, station, ten children, and the confident hope of immortality for all of us. Is it then to be wondered at that he says things which multitudes are glad to hear, and holds a position almost unique in the esteem and confidence of the public at large?
