tity of the moving water to be aggregated, and upon this followed 

 in general either a change of direction or a division of the cur- 

 rent. 



Fig. 26. Cells from the epidermis of the pericarp of Ocymum 

 basilicum, moistened with water, so that the globule of mucus 

 has expanded. Slid has torn the outer cellular Avail (a) from the 

 side walls {b). 



Fig. 27. Cells from the epidermis of the pericarp of Ziziphora 

 dasyantha. 



Fig. 28. Cells from the epidermis of the pei'icarp of Salvia 

 verticiUata. 



Fig. 29. Cells from the epidermis of the pericarp of Salvia 

 Horminum. 



Fig. .SO. Cells from the epidermis of the pericarp of Salvia 

 Spielmanni. 



Fig. 27 — 30 a. shew the remains of the side walls of the rup- 

 tured cells. 



Fig. 31. A portion of the epidermis («) and of the integument 

 [b) of the ovule of Collomia coccinea. The epidermis cells only 

 contain granules of starch. 



Fig. 32. The cells of the epidermis of the half-ripe seed of the 

 same plant, containing mostly gum, near a. some still undecom- 

 posed starch. 



Fig. 33. The same cells in the nearly ripe seed. Beautiful 

 spiral fibi'es have been formed from the entirely consumed con- 

 tents. 



Fig. 34. Cells of the epidermis of the seed of Leptosiphon an- 

 drosaceum, moistened with water, so that the globule of gelatine 

 has come out. (a) remains of the cellular walls. 



Fig. 35. Cells from the epidermis of the seed of Hydrocharis 

 viorsus ranee. In the lower part of the cells, where they are 

 connected with one another, the spiral coils take a direction dif- 

 ferent from that in the upper free part of the cells.
