with these apparently pores, and in detaching the covering, 
and the cells one from another, we increase their number. 
5. Analogy is against their being pores, no vegetable 
membrane having yet been demonstrated to be visibly 
porous. 
Dissection proves them to be not pores, they are in 
fact merely cm of attachments of the contiguous 
cells, see fig. 4 
The large size ef the intercellular spaces is evidently adapt- 
ed to the thickness of the cutis, and to allow of a free 
transmission of air, to the central green part. "These spaces 
communicate directly with the stomata. This is scarcely 
to be demonstrated by transparent sections, but is by the 
opaque, in which we see the spaces filled with air reach- 
ing frequently to the outer layer of the cutis, in which sto- 
mata abound. It is a curious fact that no intercellular spaces 
exist, nor does a transverse section give any appearance of 
pores in the cells between the midrib and outermost layer. 
These cells are angular, much more so than those not im- 
mediately adjacent to the midrib. They contain few if any 
green corpuscles, see fig l. The outer layer immediate- 
ly opposite the midrib is destitute of stomata, the midrib 
does not appear to ramify, and is well supplied with spiral 
vessels arranged in a reniform manner. 
The stem presents nothing peculiar, the cells of the 
pith abound in transparent granules. 
The stomata are small as in most succulent plants,
