298 BIBLIOGRAPHICAL NOTES. 
have received two letters from the United States, asking if I could 
ascertain the dates of issue of Hooker & Arnott’s Botany of Beechey’s 
Voyage in the ‘Blossom,’ and of Torrey & Gray’s Flora of North 
America. I have replied in general terms to my correspondents, 
but should like to put the facts which I have been able to get 
together on permanent record. ss 
The copy of Torrey & Gray 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, 1838. 
» Part 2, pp. 185-860, October, 1838. 
» Part 3, pp. 861-544, June, 1840. : 
» Part 4, pp. 545-698, Index (711), Title, &c., pp. xiv., 
rrata, June, 1840. 
Vol. ii., Part 1, pp. 1-184, May, 1841. The wrapper has no 
printing on it, but I have taken the date from Silli- 
man's Journal, xli. (1841), p. 275. 
»» Part 2, pp. 185-892, April, 1842. 
» Part 3, pp. 898-504, February, 1848. 
No more issued.
