VoLuME I 
This volume, in the folio form, presents little difficulty. It is 
true that fasc. 1 and 2 are noticed together in the B. F.* for 3 F. 
1816, while it is quite likely that they were separately published, 
one or both of them before the end of the year 1815 (the title- 
page date). As we have absolutely no data indicating the pages 
at which they were separated, however ; and as I have no strong 
evidence even in support of the supposition that they appeared 
separately, fasc. 1-2 will be treated here as a ‘‘ double number.” 
The fascicles forming Volume I folio were noticed as follows:

“se Ka 20 se 25 pl. B. F, II My. “é T 
. Ae 253% ‘“* 27 pl. B..F. 22 An... 
In all, 89% signatures and 96 plates, precisely as the folio 
volume is described above, and we need have no hesitation in as- 
signing data as follows: 
Fasc. 1-2. T.-p., pp. i-xlviii, 1-120, g/. r-gg. Ja. 1816 (or D. 1815 ?)

The B. F. gives no descriptions of fasc. 1-4 in the quarto 
form, and the following division is simply a provisional one, b 
upon the supposition that the corresponding quarto and ae 
parts contained approximately the same matter: a supposition 
Which is warranted by the known facts in the case of many of the 
later fascicles.
