592 BARNHART: DATES OF THE NOVA GENERA OF 
Sherborn and Woodward, in describing fascicle 15, say of the 
plates: ‘25 pls. 326-340.’ This is plainly either a clerical ora 
typographical error ; the 25 plates were nos. 326-349, two plates 
bearing the number “ 332.” i 
The B. F. gives us quite complete data for this volume:

The “13” plates credited to fasc. 18 probably should be 15 ; 
and in counting the folio signatures the title-pages, which in this 
case seem to have come out with the last fascicle of the volume 
instead of the first, must have been reckoned as one instead of two. 
This gives the following summary.

It will be noted that these five fascicles followed one another 
with unprecedented rapidity ; and “thereby hangs a tale.” ws 
the 26th of October, 1818, in order to fix the date of publication 
of this volume, Kunth presented a complete copy of the téxt to 
the Academy of Sciences of Paris. It consisted of loose sheets of 
the folio edition, and had a manuscript title-page, on which was 
set forth the fact that the printing was begun in September, 1817, 
and completed in September, 1818. At this time the publication 
of Volume III had only just begun, and Kunth had no idea of 
offering Volume IV to the public until it was reached in its turn 
after the completion of Volume III; in fact, the plates of Volume 
IV had not been engraved. Yet Kunth hurried the text through 
the press, and took this method of securing its advance publication. 
Henri Cassini, one of the members of the Academy, had de- 
voted his leisure “for the past eight or nine years,” as he tells % 
to the study of the Compositae, and was at that time recogni” 
as the foremost living authority upon that group of plants. 
Volume IV of the “Nova genera” comprised the Compositaé,
