Still the bare suggestion that this is the fit and proper time for speech sent me immediately to my task: from it I have returned with such results as I could gather, and also with the wish that those results were more worthy than they are of the greatness of my theme.It is not my intention to lay before you a life of Faraday in the ordinary acceptation of the term. The duty I have to perform is to give you some notion of what he has done

plete idea of the past development ofman's ancestors within the vertebrate stem by putting together andcomparing the embryological developments of the various groups ofvertebrates. And when we go below the lowest vertebrates and comparetheir embryology with that of their invertebrate relatives, we canfollow the genealogical tree of our animal ancestors much farther,down to the very lowest groups of animals.In entering the obscure paths of this phylogenetic labyrinth, clingingto the
