There are certain plants whicli will not grow in the atmosphere of a 

 crosvded ritv, ami tlierc are others wjiich thrive in the former, and will not 

 continue long in that of an alpine air. Some of the following plants grow 

 freely in the atmosphere of the crowded parts of the city of London : — 



" Plants that iiroiv frceh/ : — Sycamore, elms, niuiberries, ivies, Virginian 

 creepers, vines. Oriental planes, and hiilhoiis and tuberous rooted plants, 

 except snowdrojjs. [The ekler might be added to the trees.] 



" Plant that twists for on/i/ a few Years in pcrfcet Health : — Laburnum. 



" Plants that exist inllcaUh onlt/ a limited Time: — Privets, andChina roses. 



" Alj)ine plants scarcely ever produce flowers." 



]\Ir. Hitehe?t\s celebrated Collection of Succulent Plants at Norwich is 

 al)out to be broken up. — We are sorry to learn this fact, ami should hope 

 that some individual, or some scientific society in Norwich, will be found 

 spirited enough not to allow so great a botanical treasure as this collection 

 of succulents, to be carried away from them, and scattered abroad by non- 

 residents. Besides the fine and old specimens of rare and curious species 

 with which inspectors of this collection are familiar, numerous novelties 

 from abroad, many of them nondescripts, have, by the well known enter- 

 prise of Mr. Hitchen, been recently added to it. — Cond. 



Mushrooms grown by JStr. Callow. — Sir, I send you a few mushrooms, 

 part of the produce of a bed, made after the method I have recommended 

 in my work (seep. 213). I flatter myself that you will find the quality 

 of them equal to any that are grown in the neighbourhood of London. 

 The bed from which these were gathered came into bearing about the 

 last week in October; it has yielded an immense crop, and bids fair to 

 last yet for a month or six weeks longer. 



Cider from the French Bitter Scale. I also send two bottles of cider 

 made, in 1829, with a sort of apples which are known in this neighbour- 

 hood by the name of French bitter scale. I am sorry that I cannot 

 now send specimens of the fruit. 



The favourite Sorts of Apples for via/cing Cider, in Butleigh and the ad- 

 joining parishes. The Old Jersey, Royal Jersey, Horner's bitter scale, 

 French bitter scale, Devonshire red streak, (iin apple, and Sweet pijipin. 

 I think the Horner's bitter scale would be well adapted for the climate of 

 Scotland, as the trees never attain a large size ; the branches are pendent, 

 like those of the weeping ash, and the tree blossoms at least a month later 

 than the other sorts, yet the fruit is ripe as early as the Jersey, and the 

 Devonshire red streaks. lam Sir, yours, &c. — Edward Callow. But- 

 high, Jan. 27. 1832. 



The mushrooms were fine, fleshy, and equal to any we ever tasted in 

 point of flavour. Cider we arc no judge of, but that sent appeared very 

 good, and was certainly very strong. — Cond. 



AuT. III. Retrospective Criticism. 



CoRIiKCTinss to the preceding Number, (viz. p. 1. to 128.) — Under the 

 notice of hybrid salpiglosses, date the genealogy of S. l^arclayr/w from 

 S. stramineii and S. atropnrpurea : not from S. pkta and S. atropurpurca, 

 as there stated. This ct)rrection has been since |)ublishe(l by Mr. Sweet, 

 whose error we had followeil. Make, in conseciuence, the same correction 

 in Vol. VII. p. .in?, line 20. from the bottom. In Ime 32., also, of the 

 last-named page, for " Adem')|)hora stylosa," read " Adenophora inter- 

 media;" this being a second error into whith Mr. Sweet had been led, and 

 which he has sul)se(iuently corrccteil. The synonyme " Liparis priochilns 

 B. ('.," p 23. line 17. from the bottom, belongs not to " IMeurothdllis 

 Lanceff«»," but to " Microstylis versicolor Liudl." in the line above it: a 

 shifting of the type occasioned this error. In p. 47. lines 2. and 3. for
