Next the largest of the plants had one more shoot below. The 

 third bulb elongated its four shoots very slowly, and the largest 

 was then about 20 mm. above the surface of the soil, the others

Both were then marked afresh with Indian ink for further 

 measurements. The box was turned round to find out whether the 

 lamp-light attracted them : then there was a distinct bending in- 

 wards into the room and the light which came from it (the box

The cress since the noon of Dec. 22 had turned inwards into the 

 room ; perhaps the light there had attracted it, or else it avoided the 

 lower temperature at the window and sought the warmth. Then the 

 box was placed away from the window and upon the inner edge 

 of the table, that towards the room, where it remained standing all 

 through the night and the forenoon of the next day during which 

 time it received light irom the opposite side, from the lamps hanging 

 over the table. 



The respective heights were : — 



On Dec. 23, at 1.45 p. m. 82—63.5 mm. 



The cress was then standing upright, bending most towards 

 the side which had been illuminated during the forenoon. Then 

 the box was again placed before the window.
