April. 17' 8° a.m. sand-paper & shell lac. on several Kept on chimney-piece — Temp of water 72° at 5 Pm

(5° P.m no effect do not look all Healthy)

Ap 18' 8°. 30' a.m I can see effect on the 4 or 5 with good radicles— several others unhealthy for they got too dry in Hot-house.—

Put on gypsum on the above & immersed in water.

Ap 19' 8° a. m no effect

19th 8° 30' fixed pins & bit of glass to press on 3 of radicles.

19' 5° Pm new lot with sand-paper & bits of glass

20' 8°. 30— 3 bent from card — 3 not at all affected fixed big bits of card on 3 others

— 5° P.m 4 with large bits of card bowed — 4 with small bits or glass not affected affixed a bit of very thick card.—

21st 8° radicle bent from thick card

(I think it wd be worth while to try another series always using large & the bits of thick card.)
