“ Each Essay has been written by some one who, by lifelong study and practice of the Branch of Science to which it relates, has qualified himself to give a just and authoritative description of the work that has already been done, as well as of the bearing of that work on the present and its promise for the future. ”

“ It is the aim of the authors of these essays to present the results of experience in scientific investigation, to illustrate by concrete examples the sources of progress in a few departments of knowledge and so make clear to the layman the position of research as a factor in national prosperity. ”
