quadrilateral cellules placed end to end ; they do not differ 
from the other parenchymacal cellules, if it is not in their 
containing already a great number of these round granules, 
which form the greater part of the latex. This mode of for- 
mation is in harmony with what we observe in other organs, 
such as the spiral vessels, which are nothing but anartomosed 
cellules placed end to end. However, M. Unger has never 
been able to prove the movement of the latex , and he pur- 
poses recurring to the subject at a future time. 
Mr. Wm. Baxter of Oxford forwarded a specimen of Ma- 
tricaria Chamomilla (of which he found only a solitary plant 
in Cowley field near Oxford, on the 12th July, 1838,) differ- 
ing from the common state of the species in the florets of the 
ray being very short and rather fewer than in the common 
one. Mr. Baxter stated that he had never observed it in 
that state before, neither could he find it noticed in any of 
the Floras. The same gentleman also forwarded forty-four 
species of British willows which were obtained from speci- 
mens sent to the Oxford Botanic Garden about three years 
since by Mr. Borrer, and kindly promised to augment the 
number the first opportunity. 
NOVEMBER 2nd. 
J. E. Gray, Esq., F.R.S., President, in the Chair. 
The Secretary read the following remarks from a Member 
of the Society, on a “ Botanical Excursion to Cobham and 
Cuxton, Kent ” in company with several Members. 
The very general and indefinite manner in which our 
Florae refer to the localities producing the plants they des- 
cribe, has rendered a more particular and exact directory ne- 
cessary for the purposes of the practical student, whose 
object is not merely to amass a certain number of species, 
but also personally to visit and investigate the locality in 
which each is produced, in order that he may observe the re- 
lation subsisting between its vegetable productions, its geolo- 
gical character and its geographical position, and thus be 
enabled to deduce inferences respecting the natural distribu- 
tion and artificial culture of plants. Such directories some 
of our local Florae and Botanical Guides profess to be, but
