the same text in the folio and in the quarto form. In many 
instances, in order to determine with exactness the date of publi- 
cation of a new genus or species, it would be necessary to find out 
whether it first appeared in a folio or a quarto fascicle. A table 
showing the genera and species concerned, with the original place 
and date of publication, might prove useful in determining some 
question of priority ; but sucha list would be of very doubtful 
value until we are more certain than we can be at present of the 
exact pagination of every fascicle. It is very important, as men- 
tioned by Sherborn and Woodward, that any one possessing the 
original fascicles, or any of them, should submit them to some 
bibliographer who would publish a careful description of them ; but 
it must not be forgotten that contemporary evidence is the best, for 
a fascicle may appear to be in its original form, when actually 
altered in important particulars. 
Before proceeding to a consideration of the probable contents 
of each part, it may be well to take a general survey of the pagi- 
nation, signatures, etc., of the completed volumes. In this con- 
nection it must be remembered that the quadruple title-page in 
each volume took an entire quarto signature or two folio ones, 
While these were counted in numbering neither the signatures nor 
the pages. In some cases the French journal seems to have 
counted the title-pages in giving the number of signatures in a 
Part, in other cases, not; and the uncertainty in this respect, 
together with the fact that the title-pages were probably published 
with the first part of most of the volumes, but with the last part 
Of one or two, causes most of the trouble in definitely assigning 
certain pages to each fascicle. It must also be borne in mind that 
@ single sheet forms four folio pages, but eight of quarto size, so 
that while the quarto volumes and fascicles have more pages than 
the folio, they have fewer signatures. The plates and title-page 
_ dates are the same in both editions; it is only in the text that 
they differ,
