are admitted anywhere, we rejoin, that the individuals 
comprised ‘within their compass constitute the species. We 
care not how wide this compass may be taken. The per- 
petuation of groups of consimilar forms appears to us suf- 
ficient proof, that some check in this respect is main- 
tained in the rule of nature. If the case were otherwise, 
chaos might not be a chimerical view in the prospect of the 
universe ; the mind of man might be appalled by strange 
and unforeseen appeafances, while he himself might appre- 
hend, if such assumption were admitted, that his own race 
had no security from passing into some other mode of 
being. . 
In respect to hybridous mixture, we have elsewhere 
ventured to suppose, that the infiuence of either of the 
procreating types might be more or less predominant, and. 
that, where the produce is continued by succeeding genera- 
tions, it finally resolves into one or other of those from 
which it sprung. It is true, that this proposition cannot at 
present be supported throughout by actual experiment; but 
then it is opposed to one where reason and experience ap- 
pears to us to be defied in every part. 
Our belief is, that nature can be scanned in her works 
in no other way than by the products of revolving periods, 
during which the countervailing processes by which she re- 
_ duces her apparent aberrations are in progress; and that. 
when these can be taken into account, her true rule is 
made manifest. ; ; 
The subject of the annexed drawing was raised in the 
hothouse at Boyton. The seed was sent from Demerara to 
Mr. Lambert, to whom we are obliged for the sample for 
description, which however was not completed from the 
fresh flower. 
We have not identified the plant with any recorded 
species. Among the unpublished engravings in Mr. Lam- 
bert’s library, there is one intended for a work of Plumier’s, 
which clearly represents either one of the same species, or 
else one of the same genus. It was pointed out to us by 
Mr. Don, to whose assistance we owe much contained in 
the description of this species.
