State after showing that too high a temperature stops action, that X in latter part of December during severe frost 18 beans were tested for sensitivity with little square affixed with shell-lac & gum & only 6 were deflected to opposite side, & this in very slight degree & very slowly.— The case jar was kept either on chimney piece or table of sitting-room.

yet slowly — some had been germinated in water — others in peat or sawdust—

The whole case a mystery to me.

(The evidence here is worth very little but as far as it goes it shows that minute bends of shell-lac, equal to that used in affixing cards, produce no effect)
