To Prof. W. H. Venable, who reviewed the manuscript of this work, I am indebted for many valuable suggestions, and I call not speak too kindly of him as a critic.

The illustrations, excepting those mechanical and historical, making in themselves a beautiful narrative without words, are due to the admirable artistic conceptions and touch of Mr. J. Augustus Knapp.

Structural imperfections as well as word selections and phrases that break all rules in composition, and that the care even of Prof. Venable could not eradicate, I accept as wholly my own. For much, on the one hand, that it may seem should have been excluded, and on the other, for giving place to ideas nearer to empiricism than to science, I am also responsible. For vexing my friends with problems that seemingly do not concern ill the least men in my position, and for venturing to think, superficially, it may be, outside the restricted lines of a science bound to the unresponsive crucible and retort, to which my life has been given, and amid the problems of which it has nearly worn itself away, I have no plausible excuse, and shall seek none.
