June 6^th 1879' Phaslitis nil = Ipomaea caerulea
Obsrved at noon «in Hothouse»^t1 & 10° P.m
Pot. I. Plnt (1) Both Cots Horizntal at noon : at 10° P.m both 48° beneath Horizon
   Plant (2) 1 Cot 10° below horizon— th othr horizntal— at 10' P.m. th frmer 60° below horzon, th othr 37° belw Horzn
   Plant (3) at noon I believe about horizntal;^. at night both 48° beneath horizon 37°—50°^{t2 t3}

Pot II. Plant (1) at noon both Cots horzntal— at 10° P.m, one 25° & th othr 35° beneth horizon 25°^t4
   Plnt (2) both Cots hrzntal «but sloping laterlly» at nigt, one 54° benth horizn & othr 79° 79°^t5
   Plan (3) ‹not› at noon I believe both about horizntal , at nigt both about 30° beneth horizon abut 30°^t6

Pot III
Plnt (1) yng with ‹vy› small Cotyledons both Cots at noon Horizntal; at 10° P.m; one cot horizontal— th othr 20° above horizon!!!^t7
  Plan (2) one cot 5° abve horizon, th oth horzntal; at night both 32° benth horizon
  Plnt (3) I believe Cots both about horzntal at noon at night about 30° beneth Horizon.—
All these seedlig had large Cotyledons «with minute plumule developed» (except 1 in Pot III.) & all certainy fall consideraly, but not enoght to be calld sleep.
