'dividing the vascular circle into numerous compact 

 segments.' A* ray 'cannot divide anything into a seg- 

 ment. Only a partition, or a knife, can do that. But 

 we shall find presently that marrow -rays ought to be 

 called marrow-plates, and are really mural, forming more 

 or less continuous partitions. 



(4) The compact segments 'consist of woody vessels 

 and of porous vessels.' This is the first we have heard 

 of woody vessels/ He means the ''fibres ligneux' of 

 Figuier ; and represents them in each compartment, as 

 at C (Fig. 25), without telling us why he draws the 

 woody vessels as radiating. They appear to radiate, in- 

 deed, when wood is sawn across, but they are really up- 

 right. 



(5) A moist layer of greenish cellular tissue called the 

 cambium layer black in Figure 25 and he draws it in 

 flat arches, without saying why. 



(6) "] Three layers of bark (called in his note Endo- 



(7) | phlceum, Mesophloeum, and Epiphloaum !) with 



(8) j ' laticiferous vessels.' * 



(9) Epidermis. The three layers of bark being sepa- 

 rated by single lines, I indicate the epidermis by a 

 double one, with a rough fringe outside, and thus we 

 have the parts of the section clearly visible and distinct 



* Terms not used now, but others quite as bad : Cuticle, Epidermis, 

 Cortical layer, Periderm, Cambium, Phellodcrm six hard words for 

 'BARK/ says my careful annotator. "Yes ; and these new six to be 

 changed for six newer ones next year, no doubt."
