"The copy of Torrey & Gray [Flora of North America] in the library 

 of the British Museum. Bloomsbury, is in its original buff paper wrappers, 

 and from this I can submit the following statement as accurate, so far as 

 the dates are correctly set out on these wrappers: — 



Vol. i., Part i, pp. 1-184, July, 1838. 



Part 2, pp. 185-360, October, 1838. 

 Part 3, pp. 361-544, June, 1840. 



Part 4, pp. 545-698, Index (711), Title, etc., pp. xiv.. Errata, 

 June, 1840. 



Vol. ii. , Part i, pp. 1-184, May, 1841. The wrapper has no printing on 

 it, but I have taken the date from Silliinan^s Journal, xli. (1841), p. 275. 

 Part 2, pp. 185-392, April, 1842. 

 Part 3, pp. 393-504, February, 1843. 

 No more issued. 



The case of Hooker & Aruott [Botany Beechey] is not so easy, for I 

 have not succeeded in finding any copy with the original wrappers, and the 

 following dates can only be taken as probable. If any reader of t\i& Journal 

 of Botany has access to such a copy, and would communicate to me the 

 actual printed dates, I should be extremely obliged. 



There is no difficulty in ascertaining the date of the first part, as several 

 announcements concur; thus in Lmnoea the issue is given as containing pp. 

 1-48, with ten plates, and came out in 1830. As I have failed to find more 

 than occasional allusions during the progress of the work, I have pieced 

 together all such indications, and assuming that each part was of the same 

 dimensions as the first, I have referred to Pfeiffer's Nomenclator for the dates 

 of all new genera as below, as the dates therein given must have been gath- 

 ered from some copy : 



Part I, pp. 1-48, in 1830 (as above). 



Part 2, pp. 49-96, in 1832 {Pterochilus). 



Part 3, pp. 97-144, in 1832 {Adenostoma). 



Part 4, pp. 145-192, in 1833 {Layia; see also Torr. & Gray, ii., 392, in 

 confirmation). 



Part 5, pp. 193-240, in 1836 {Anisopapptts'). 



Part 6, pp. 241-288 (no indication of date, owing to the absence of any 

 new genus).
