Barnhart : Dates of Elliott's Sketch 681 



by his friend, Dr. Darlington. By reference to pp. 202, 248, 249, 

 and 585, it is made out that the first number of Elliott's work was 

 issued as early as October, 18 16, was recalled, reprinted, and 

 issued anew, along with the second number, before January, 18 17. 

 The first number probably ended on p. 96 ; the second on p. 222. 

 The third and fourth numbers were published before November 10, 

 1 81 7. The fourth number must have included p. 466 : the fifth 

 and concluding number of the volume (to which the title-page 

 assigns the date of 1821) must begin on or before p. 529. For, 

 on the latter page Nuttall's genus DiamorpJia occurs, and his work 

 is for the first time cited, while the prefatory list of decandrous 

 genera, on p. 466, does not contain Diamorpha. 



"This is confirmed by Elliott's correspondence with Zaccheus 

 Collins, now in the possession of the Academy of Natural Sci- 

 ences, Philadelphia, which Mr. Redfield has kindly consulted at 

 my request ; from which it appears, in short, that No. 1 was first 

 issued, September 26, 18 16; No. 2, on or before February 19, 

 1817 ; No. 3, on or before April 3, 1817 ; No. 4 and No. 5, no 

 data found ; No. 6, the commencement of the second volume, ap- 

 peared on or before October 12, 1821. The title-page of this 

 volume bears the date of 1824." 



The unfortunate assumption, reiterated in the foregoing note 

 that No. 5 completed the first volume and No. 6 commenced the 

 second one, vitiates much of Gray's argument. The error is cor- 

 rected, but no particular attention is called to its importance as af- 

 fecting the main line of argument in the further note (Am. Journ. 

 Sci. III. 13: 392. My. 1877): 



" Date of the Parts of Elliotts Botany. — Referring to our note 

 in the January No. of this Journal, it is worth recording that the 

 first fasciculus actually ended, as was supposed, on p. 96. No. 5 

 consisted of pages 401-496, and bears the date of 18 17. No. 6 

 contained pages 497-606, and is dated 1 821. This information is 

 obtained from the inspection of copies of those parts in their orig- 

 inal state, and is obligingly supplied by Mr. F. B. Dexter, of the 

 Yale College Library." 



It will be seen that the most accurate evidence given in these 



two notes relates to No. 1. It consisted of pp. 1-96, was origi- 

 nally issued Sept. 26, 18 16, was recalled, reprinted and reissued 

 with No. 2, but Gray makes no reference to the cause of this re- 

 printing. In an "advertisement," published, I believe, with No. 

 4, Elliott states a reason for this procedure. He says : " The first 

 and nearly half of the second Number of this sketch had been
