✦ Synopsis

Less rigidly scientific, but not less interesting, is the lecture on " String Figures '"the string figures we all held on our hands years ago, wherein we learn that there is a whole book on the subject. Edward McCurdy presents Leonardo da Vinci as a rare combination of the artist, the scientist and the technician. And how modern was he! " He contemplated the use of poisonous gas or powders in naval warfare for the purpose of suffocating the enemy, and told how to make a simple preventive mask. He also contemplated the contingency--as happened on occasions in Flanders--of an adverse wind causing the pmson to recoil upon the users." G.F.S.
