Mém. de la Soc. des Sciences des Bordeaux Tom IV. 1866 p. 11. M. Paul Bert "Mouvements de la Sensitive" Mimosa pudica

p. 25 The most excitable part is the inferior part of the swelling up the bases of the primary petioles, & the upper part of the swellings at the base of the leaflet. (exposed to rain C.D.)

p 25 the parenchyma of leaf is inexcitable — one may prick leaflet, between the nerves & cause no effect. — It is the reverse, if the nerves are pricked. —

p. 26 The bark of a petiole can be removed with care & no movement. — Thus the tissue cellular of the swellings (like Dionæa?) & the fibro-vascular tissues are the sides which are excitable—

p. 26 Transmission effected solely by woody bundles, as proved by Dutrochet—

The transmission proceed in 2 ways up & down stems & petioles.

p. 31 The swellings at the bases of petioles & leaflets are both excitable & the motors.—

M. Bert in a subsequent paper in same vol. p. 54 concludes that Ether & Chloroform attack with animals only the nervous centre — neither the sensory nor motors nerves nor the muscles not being are affected.—
