Oxalis acetosella

Nov. 5th.

Placed roots, after examining them, in sol. of 7 to 1000 at 8°. 30' & in a few minutes some aggregation.

After about 1/2° in all the rows of cells close to tip spherical agglomeration of granules— Higher up, here & there a single cell, or 2, 3, 4 or even 5 cells in a row filled with hyaline granules; in some cells these were few in number & large, consisting, as seen by outline, of almost confluent small globules, which when watched for 1/2° did not change shape. Beneath these epidermic cells, there was finer granular matter in the cells of the underlying layer

Higher up there were considerable length of the same root-let with no aggregation in the epidermic cells. Yet afterwards still higher some reappeared — Case like that of Ox. corniculata — Though I looked at many granular cells I cd never see a root-hair arising from one.; & there were many root-hairs.—

Nov. 5th

Oxalis sepium, added at 11° 25' under cover glass 2 drops of Sol. of 7 to 1000 & in 20' copious aggregation in cells beneath epidermis, but not in latter —

Nov. 6th 8° 30' a.m. no change — no clear agg, in epidermic cells— plenty in underlying cells— rather curious.

(Both these plants grew in saucer & had been much starched)

Oxalis (with small leaves & yellow flowers)) only here & there aft 30' (treated as above sp.) traces, yet distinct of granular matter in the underlying cells, & a few minute hyaline particles in epidemic epidermic cells, close to tip of root. —

Nov. 6' 8° 30' a. m no agg. in epidermic cells, well marked in isolated underlying cells — ie in layer beneath epidermis.—
