Nov 28 8° 20' a.m. S.W. Window [Drawing] room Bright day
Canary grass
several seedlings with caps of tin foil protected from light on all sides except S.W. window
2° 40' 2 somewhat bent & 2 not so. — None of tall-ones bent!— 4° I found 1 more bent, but bent transversely to light, & the caps on all were loose so might have admitted reflected light from soil.—
