This book is not a useless dictionary or semi-dictionary of phrases or *puns to be used in hypothetical solution-cases. It is a study ‹of the› and exposition, *conduced in the simplest language, of the general [mental] laws underlying [↑ governing] the psychol[ogical] processes by which solutions of problems are obtained, so that by a simple observance of them and training in their observance, the reader can render himself apt to become a competent problem solver.

(1) Problems proper, containing a [↑ final] solution to be found — such as pictures to be deciphered into one certain meaning.

(2) Skill contests, such as "Samples" *Ballotus, etc, which consist in ‹discovering› /drawing\ up phrases

(3) Half-chance contests — such as guessing who will win, lose or draw on a Certain nº of [↑ e.g.] future turns to play on a certain date.

(2) Those which depend on letters
