Light

Pot with seedlings from Hot House put at 12°. 45' behind book-case in study at 4° 50' (& before) cots very little or not at all affected by dimness — at 10° about 90° together so considerably raised, but cannot be said to sleep.

Temp

On 27th put in Hot-case temp. often 80° F, & brought into study late in evening, on 30th after 3 or 4 days but I could see no signs of sleep or even of elevation of Cots!!!— Yet some of seedlings, showed only trace of true leaves, so in good state too Hot.— ã
