Abstract
ON Saturday, March 15, at noon, several twigs were torn off a sycamore but no “bleeding” took place at the time or so far as I know on Sunday, but on Monday morning at 8.30 (say 44 hours after the injury) what were at first taken to be raindrops were visible on each of the 8 or 10 wounded surfaces. As there had been no rain and the liquid was slightly sweet, it was evidently sap, but the strange part is that it happened so long after the injury and that it was not repeated to-day (Tuesday), 72 hours afterwards.
