‘“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 1, pp. 1-184, July, 
t 2, pp. 185-360, Baber at 
Part 3 3, pp. 361-544, June, 1 
Part 4, a hele ae oe Title, etc., pp. xiv., Errata, 
Jun 
Vol. ii., Part 1, pp. 1- ee May, 1841. The wrapper has no printing on 
it, but I hee taken the date mon Silliman’s Journal, xli. (1841), p. 275-

1-48, with ten plates, and came out in 1830. AsI have failed to find more 
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 1, pp. 1-48, in 1830 (as abov 
Part 2, pp. 49-96, in 1832 pepo 
Part 3, pp. 97-144, in 1832 ( Adenostoma).
