are admitted anywhere, we rejoin, that the individuals 

 comprised m itbin their compass constitute the species. We 

 care not how wide this compass maybe taken. The per^ 

 petuation of groups of consimilar forms appears to us suf- 

 ficient proofs that some check in this respect is nuiin- 

 tained in the rule of nature. If the case were otherwise, 

 chaos might not he a chimerical view in the prospect of the 

 universe ; the mind of man might be appalled by strange 

 and unforeseen appearances, while be liimself might appre- 

 hend, if such assumption were admitted, that liis 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 influence 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 Among the unpublished engravings in ]Mr.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 Phimier'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.
