Pleased JSBS has decided to work on Drosera; sends plants. Does not know whether thermo-electric pile could detect temperature change when leaves close.
CD’s experiment with very weak hydrochloric acid repeated with success: the plants digest albumen more quickly.
Thanks TFC for his extremely interesting paper ["On the fertilisation of the New Zealand species of Pterostyles", Trans. & Proc. N. Z. Inst. 5 (1872): 352–7]. Has no doubt his explanation [of the fertilisation mechanism] is correct. The case is analogous to that of the Cypripedium though TFC’s case is much more curious.
