"Summary of Tendrils"
To give idea of force of syringe, I may say that the lightest jet, however lightly given from it caused all the leaves of Mimosa to mistakenly bend, when the 1/32' gr loop of thread, rolled into a ball did not act on gland at base of leaflet.— This, however, is no safe criterion, for t I have ascertained, with other plant, that some are sensitive to excessively
slight impact & not to slight pressure; where the sensitivity of others is reversed, for t —. are affected by excessively slight prolonged pressure & are indifferent to a momentary blow.—
