This volume consisted of fasc. 19-23, and the B. F. furnishes 
quite a complete account of them, except in the case of quarto 
fasc, 21, which probably was composed of 12 signatures.

Six fascicles constituted this volume, viz. nos. 24-29. Of 
these the B. F. gives data for quarto fasc, 24-26, and all the folio

assigned to fasc. 24, unless many of the earlier plates were re- 
issued at this time. This makes the numbers of the plates in 
fach fascicle of this volume quite doubtful :

In noting the folio, the title-page seems to have been counted

_ included, and may have appeared with a later fascicle. From the
