Abstract
AT the meeting of the Royal Dublin Society on January 25 last, as reported in NATURE for February 24, p. 850, I described a form of ultramicrometer in which the minute movement of one plate of a parallel plate condenser, forming part of a thermionic-valve oscillating circuit, is recorded by a galvanometer. We are now applying this apparatus to the study of plant-growth, and as some of the preliminary observations show very clearly the pulsations of growth described by Sir J. C. Bose, it may be of interest to give a short account of these results.
