(1.) A young radicle, 4 mm. in length, had a card fixed behind:  after 9 h. deflected in the plane in which the bean is flattened, 50o from the perpendicular and from the card, and in opposition to Sachs’ curvature:  no change next morning, 23 h. from the time of attachment.

(2.) Radicle 5.5 mm. in length, card fixed behind:  after 9 h. deflected in the plane of the bean 20o from the perpendicular and from the card, and in opposition to Sachs’ curvature:  after 23 h. no change. [page 136]

(3.) Radicle 11 mm. in length, card fixed behind:  after 9 h. deflected in the plane of the bean 40o from the perpendicular and from the card, and in opposition to Sachs’ curvature.  The tip of the radicle more curved than the upper part, but in the same plane.  After 23 h. the extreme tip was slightly bent towards the card; the general curvature of the radicle remaining the same.

(4.) Radicle 9 mm. long, card fixed behind and a little laterally:  after 9 h. deflected in the plane of the bean only about 7o or 8o from the perpendicular and from the card, in opposition to Sachs’ curvature.  There was in addition a slight lateral curvature directed partly from the card.  After 23 h. no change.

(5.) Radicle 8 mm. long, card affixed almost laterally:  after 9 h. deflected 30o from the perpendicular, in the plane of the bean and in opposition to Sachs’ curvature; also deflected in a plane at right angles to the above one, 20o from the perpendicular:  after 23 h. no change.

(6.) Radicle 9 mm. long, card affixed in front:  after 9 h. deflected in the plane of the bean about 40o from the vertical, away from the card and in the direction of Sachs’ curvature.  Here therefore we have no evidence of the card being the cause of the deflection, except that a radicle never moves spontaneously, as far as we have seen, as much as 40o in the course of 9 h.  After 23 h. no change.

(7.) Radicle 7 mm. long, card affixed to the back:  after 9 h. the terminal part of the radicle deflected in the plane of the bean 20o from the vertical, away from the card and in opposition to Sachs’ curvature.  After 22 h. 30 m. this part of the radicle had become straight.

(8.) Radicle 12 mm. long, card affixed almost laterally:  after 9 h. deflected laterally in a plane at right angles to that of the bean between 40o and 50o from the vertical and from the card.  In the plane of the bean itself the deflection amounted to 8o or 9o from the vertical and from the card, in opposition to Sachs’ curvature.  After 22 h. 30 m. the extreme tip had become slightly curved towards the card.

(9.) Card fixed laterally:  after 11 h. 30 m. no effect, the radicle being still almost vertical.

(10.) Card fixed almost laterally:  after 11 h. 30 m. deflected 90o from the vertical and from the card, in a plane intermediate between that of the bean itself and one at right [page 137] angles to it.  Radicle consequently partially deflected from Sachs’ curvature.
