314 COMPOSITE ORGANS. CHAP. II. 



dexterity in experiments of this kind was certainly 

 not inferior to Saussure's, admits, as has been 

 already seen, the existence of two distinct lamina 

 in the net-work of the epidermis, which, however, 

 he acknowledges he was never able to separate ; but 

 does not represent the exterior pellicle as being des- 

 titute of organization. 



But whether the exterior and unorganized pellicle 

 of Saussure exists or not, the accuracy of his ob- 

 servations upon the whole will still entitle them to 

 the regard of the botanical anatomist, who will be 

 able to judge of the fidelity of his representations by 

 comparing a few of them with the original. Par- 

 ticularly, let him consult the case in which he dis- 

 tinguishes the structure of the epidermis of the 

 petals from that of the leaf, as exemplified in the 

 epidermis of the Pink and Pansy, to which there 

 may be added, as affording also a good example, the 

 epidermis of the inner surface of the petals of 

 Cocus vernus, whose multitudes of minute and shin- 

 ing points, certainly resemble more the emerging 

 vesicles of Saussure than the pores of Hedwig.
