Barnhart : Dates of Elliott's Sketch 



until the work is completed. " It is plain that this promise was 

 not kept, but in view of this announcement it is not likely that 

 many months elapsed between the appearance of Nos. i and 2. 

 As one is dated 1821 and the other 1822, it is altogether probable 

 that No. 1 was published late in 1821, and No. 2 early in the fol- 

 lowing year. Of the remaining numbers I have no data at hand, 

 but I think we shall not be far out of the way if we assign 1822 

 to No. 3, 1823 to Nos. 4 and 5, and 1824, the title-page date, to 

 No. 6. Perhaps some one who reads these lines may possess 

 original copies of these numbers, and can furnish their pagination 

 and dates. It happens that the exact dates of these numbers are 

 not quite so important as those of the others, for during these years 

 1 822-1 824 there was a remarkable hiatus in the publication of 

 works relating to American botany, and I know of no question of 

 priority involving the dates of these parts. 

 We may sum up Volume 2 as follows : 



No. 1 

 No. 2 

 No. 3 

 No. 4 

 No. 5 

 No. 6 



Pp. 1- 1 04, 1 82 1, probably late in the year. 

 Pp. 105-208, 1822, probably early in the year. 

 Pp. 209-312, 1822 ?. 



p P- 3I3-4I6, 1823 ?. 

 Pp. 417-520, 1823?. 



Pp. 521-743, pl. 7-12?, 1824.
