Sept 21 The first pair of small true leaves was open in morning & closed at vertically upwards exactly like Cotyledons; & this morning (22d) at 6º 45' a.m, they were again open. (—First case of true leaves behaving like cotyledons. — I suppose they are cotyledons?) What a contrast to Sida!

Sept. 25' 10º 15' P.m. The cots; are not at all asleep; But the first true leaves of 1 seedling (marked with bits of stick) which at 12º 30 at formed together an angle of 62º at 10º 15 formed angle of only 8º, so each cot leaf had risen 27º— with a second seedling (marked with pin) the cots leaves did formed at 12º 30 angle of 70º, at night only 8º, so each had risen 31º— 90 [-] 35 [=] 55

Sept 30th This 2d pair of leaves at 4º 15' formed angle together of 96º, & at 10º P.m of 69º, but this rise not sufficient to give appearance of sleep.— The angle third & young pair of leaves at same hour was 20º & at night only 5º & then on all the young plants appeared asleep. — (over

Oct. 28 The 6th pair of leaves stood formed together at noon angles of 21º & at 9º P.m were closed except divergent tips; these tips at noon were 1.04 inch apart, & 9º P.m only .43 of inch apart.— In another plant, with a 6th pair of very young leaves I cd perceive no difference at noon & night.
