    compared with responses given at the same temperatures while warming (see table). Temperature variation thus seems to have a stimulating effect on response, by increasing molecular mobility in some way. The second Fig. 40. — Records of Responses in Euchabis Lily dubing Rise and Fall of Tempebatube Stimulus constant, applied at intervals of one minute. The temperature of plant-chamber gradually rose on starting current in the heating coil; on breaking current, the temperature fell gradually. Temperature correspond¬ ing to each record is given below. Temperature rising: (1) 20°, (2) 20°, (3) 22°, (4) 38°, (5) 53°, (6) 68°, (7) 65®. Temperature falling : (8) 00°, (9) 51°, (10) 45°, (11) 40°, (12) 38°. record (fig. 40) shows the variation of response in Eucliaris lily (1) during the rise, and (2) during the fall Table showing the Variation op Response in Scotch Kale DURING THE RlSE AND FALL OP TEMPERATURE Temperature Response Response [Temperature rising] [Temperature falling] 19° C. . . . ; • • • - 25° „ . . . . . . 24 „ . . . • • • 30° „ . . . . . 11 „ . . . . 23 dns. a < 50° „ . . . . 8 „ . . . ... 16 70° „ . . . i .. 7 , P 2
