knowing each other's tasks, yet happy in the consciousness of 

 being more usefully and more honourably employed than in 

 imperfectly attempting the execution of works which they might 

 individually complete. The exquisite piece of mechanism which, 

 in the form of a watch, issues from the manufactories at Paris 

 or Greneva, has its various elements of its wheels and pinions, 

 its balance and fusee, collected from the detached cottages of 

 the peasantry of the Jura. 



To combine individual effort, to render parts capable of com- 

 bination into a whole, to economize time, and thus virtually to 

 lengthen the lives of those whose exertions are valuable in the 

 cause of science, may be considered as humble, yet surely most 

 important, contributions to its advancement. We shall have 

 little reason to regret the want of a National Institute, whose 

 existence is the just subject of pride to our continental neigh- 

 bours, so long as individual exertion can supply the stimulus 

 which even the sunshine of wealth and patronage has sometimes 

 failed to excite. 



New Genera of Plants. Communicated by G. A. Walker-

Since the pubHcation of the paper on Indian plants in this 

 Journal, No. 29, by Dr Wight and myself, we have received 

 specimens in fruit of Bragantia WaUichii (p. 181.), which ena- 

 ble us to state that the pod-like capsule is not terete, as we de- 

 scribed it, on the authority of Rheede''s bad figure, but tetrago- 

 nal, with the angles very sharp : this plant, moreover, is pre- 

 cisely the same as Trimereza piperina, Lindl., in his observa- 

 tions under Aristolochia cymbifera, 1. 1443 of the Botanical Re- 

 gister. I may also here remark, that I have now ascertained 

 that the genus Bhesa, described by me also in this Journal, 

 No. 32, p. 315, is the Kurrimia of WaUich; that B. Moja, Ham. 

 is K. pukherrima., Wall. ! List, n. 4334 ; and that B. panicu- 

 lata is K. paniculata, Wall. ! L. n. 4336. I had no suspicion of 

 Kurrimia (which I only lately saw in Dr Hooker's herbarium) 

 being the same as Dr Hamilton's genus, partly from Wallich not 

 referring to Hamilton's specimens, and partly because /^e'« fnacro-
