distance from pane of glass to centre of axis at front of petiole of leaf observed 8 1/8 inches, but the line was greatly inclined

Moved horizontally .83 of an inch in actual distance — vertically 1.2 ⎯⎯ do. do} This refers to apex of leaf, & therefore includes small movement of petiole & probably still smaller movement of shoot or axis i.e. to extreme distance travelled during its whole course

movement of petiole, as judged by tip of leaflet supposing this whole leaflet to have been rigid, for comparison, with the real movements of leaflet petiole alone & of leaflet together with petiole

Extreme movement in horizontal line — 16 of an inch .32

— vertical line — .17} I may say that I fixed bit of paper as long as leaflet

Extreme movement in horizontal line of tip of main leaflet (at the same time) with & including that of the above petiole)—.16 of an inch— XX

XX so that it appears that leaflet must have moved in opposed line to the movement of petiole, for the paper tip leaflet, if rigid (see z) would have moved, owing to movements of petiole .32 of an inch instead of as here only .16.

Vertically the movement of leaflet has increased exceeded that of petiole in the proportion of .32 to .17
