STRUCTURE OF 3 
which are interspersed many very irregular bundles of woody 
matter. The pith is altogether similar to this portion; op- 
posite each annulus or formation of leaves it is traversed by 
vessels. 
Each formation of wood is connected by ligneous facicles 
passing between each other. The inner woody formation 
is continuous, diminishing exceedingly at the apex of the 
trunk. 
It is obvious from the small number of concentric circles 
compared with the formations of leaves, that these do not 
correspond, or rather that more than the wood of one forma- 
tion of leaves enters into the composition of each circle. 
In the prostrate tfunk, the development of the wood was 
carried to excess on the decumbent side, on the opposite-ene 
there were three formations, the outer of which on reaching 
the commencement of the excentricity appeared to divide 
into 2. On this side 7 distinct formations may be counted, 
the last being exceedingly irregular from the woody matter 
passed freely into the roots. 
o great knowledge of the structure of these remarkable 
parts will be attainable, but by close observation of all stages 
intermediate between that of the lst development of the 
stem aud its subsequent maturity. It is obvious that the 
woody matter is deposited in cones. 
Connected with this excentricity there was no dedu AL 
the regularity of the corona. 
This is obvious if there are 3 zones in the lower, 2 in the 
centre, and one only at the apex. It is essentially exoge- 
nous, the latest fibres developed by the terminal, being always 
outermost: Dr. Mohls’ statement appears to me to have no- 
thing here to corroborate it. 
Mr. Brongniant’s opinion that the layers are not to be 
considered as analogous to the same number of layers of di- 
cotyledonous wood, is also incorrect. What the relations are 
which these have with the epochs of inflorescence and folia- 
tion can only be cleared up, as he observes, by the examina-
