Barnhart : Dates of Elliott's Sketch 687 



No. i. Pp. 1-96, pi. 1-2, originally issued September 26, 

 18 16; recalled, reprinted and reissued with No. 2. This number 

 (at least when reissued) contained an ''Advertisement " of two 

 pages (pp. i-ii) and a Glossary of 14 pages, both usually missing 

 from bound copies of the work. 



No. 2. Pp. 97-200, almost unquestionably appeared in Decem- 

 ber, 1 8 16. 



No. 3. Pp. 201-296, March, 181 7. 



No. 4. Pp. 297-400, October, 18 17. Plates 3 and 4, which 

 illustrate species described in No. 1, seem to have been distributed 

 with No. 4 — also supplementary pages iii-vi, containing the " ad- 

 vertisement/' nearly all of which is quoted above after Gray's 

 notes, and descriptions of several species of Panicum and Agrostis.

These supplementary pages are usually found at the end of Volume 

 I. of bound copies of this work, but appeared with No. 4.

No. 5. Pp. 401-496, 18 17, probably December. 



No. 6. Pp. 497-606, 1 82 1, probably early in the year. 



All that has been said thus far relates to the dates of the first 

 volume. Until recently I was under the impression that the 

 second volume was not issued in parts, but appeared as a whole 

 in 1824. It is true that Gray says, " No. 6, the commencement 

 of the second volume, appeared on or before October 12, 182 1," 

 but we have seen that No. 6 was not the commencement of the 

 second volume. However, a few months ago I secured copies of 

 the first and second numbers of Volume II. in their original covers. 



No. 1. Pp. 1-104, is dated 1821. 



No. 2. Pp. 105-208 is dated 1822. 



This time, it will be noticed, the numbers did not consist of 

 twelve and thirteen signatures alternately, but of thirteen signa- 

 tures, or 104 pages, each. From a careful inspection of several 

 bound copies of this volume it seems likely that this size was con- 

 tinued through the remaining parts. Plates 7-12, although almost 

 entirely devoted to plants described in the first volume, were not 

 issued with any of the parts of that volume, nor with parts 1 and 

 2 of the second volume. When plates 5 and 6 were published I 



cannot say. 



On the back cover of Vol. II., No. 1, is the statement : " This 



work will be comprised in twelve numbers, to be published monthly
