Pots laid Horizontally

Exposed for 46º to Apogeotropism

No effect. The stem fell nearly whole time for very short space probably merely gravity in slightly zig-zag line, which possibly indicate slightly circumnutation. & they moved obliquely to left on which side I held candle, but I doubt whether due to this— Young stem of Cyperus, not quarter grown— Young frond of Fern. — Observe

April 10' After keeping upright for a day the Fern & Cyperus placed vertically with same marks, & traced on Hor. glass in darkness. to see if any movement, when vertical.— perhaps too cold to grow in study — if so test Apogeotropism in Hot-House

Fern Left Hand           Cyperus right Hand

8º 30'   8º. 30'

11º 10    hardy any change     11º 10'    an atom from light & to right

1º      do           1º    hardly any change .

4. 30    no change        4º 30    no change

7º 30' a m    little to light        7º. 30'    hardly moved

9º    do             9º    do

As Cyperus nutated well when in Hot-House I suppose my study too cold for it or Nephrodium to nutate — but this very odd as weather not very cold— & fire in room —  Whole case very odd
