At the time when the first edition of this little book was published in 1916, I expected to issue a second volume shortly after, dealing with frequency curves and frequen(7 surfaces as well as the related problem of co-variation (correlation). The manuscript for this volume was completed and printing had already commenced on some of the chapters, when a series of misfortunes, not necessarily unexpected, overtook the work. A major part of the manuscript while in transit to a friend in Denmark for review and corections went down with a Danish vessel when torpedoed by an outlaw German submarine. A duplicate copy was for some reason or other withheld by the British military censor and not returned to the writer until long after the termination of the world war. My third and final copy of the manuscript, which I had submitted to an American friend for critical review was also lost in transit. The veritable nemesis which seems to have followed my efforts is, however, only a verification of the all prevailing laws of chance, which every serious minded student must face with unperturbed attitude. In fact, the above misfortunes have, after all, only made me more determined to complete another collection of notes, which 1 eventually hope to put into proper shape for pubUcation.
