<div dir="ltr">Hello Barbara,<div><br></div><div> I believe these might be "Press figures", which Carter describes in "ABC for Book Collectors" as: </div><div><br></div><div>"Numerals, letters or symbols printed in the lower margins of many 18th century English books (and a few American) normally on the verso of the leaf and seldom therefore liable to be confused with signatures.

Each press or pressman was assigned a mark, and these were used for computing piecework earnings ...."</div>

Calling on those with more experience than I...<br>
<br>
I am cataloging a copy of the 1st ed. (London: J. Johnson, 1771) of
<i>The natural history of the human teeth : explaining their
structure, use, formation, growth, and diseases</i>. by John
Hunter. [8], 128, [16] p. 28 cm. 4to (plus 16 plates, but I'll
address those below)<br>
<br>
In attempting to record the signatures I notices some anomalies that
I didn't understand.<br>
<br>
First, ignoring the anomalies, the volume is gathered and signed as
[A<sup>4</sup>] B-T<sup>4</sup> <br>
<br>
The plates are numbered, interleaved and sewn-in between the leaves
of S-T<sup>4</sup>, each plate facing the page that describes it.
From examination of the chain lines, S-T<sup>4</sup> appear to still
be 4to gatherings and not singletons.<br>
<br>
The real anomalies are numbers (and an occasional letter) that
resemble signature marks, but are in addition to the alphabetic
sequence above, and do not appear where one would expect them to be.
<br>
<br>
For example, the leaves in signature B<sup>4</sup> are marked: B
B<sup>2</sup> [blank] [blank], as one might expect. But on the
verso of B2 is the Arabic numeral 6 and on the verso of B3, the
Arabic numeral 4. These numbers are centered at the bottom of the
page, apart from the catchwords.<br>
This first caught my eye in C<sup>4</sup> which is marked: C C<sup>2</sup>
4 7 although there are no markings on the verso in this case.<br>
At first I thought perhaps it was some notation to show
cancellation, but the 4to gatherings seem to be intact, and with the
exception of A<sup>4</sup> (which is completely unsigned) and S<sup>4</sup>,
all of the signatures have at least one of these odd additional
markings.<br>
<br>
I will happily ignore these extra markings if they are unimportant,
but I do not have the experience to know!<br>
<br>
Thank you, I hope I haven't asked a question with an embarrassingly
obvious answer!<br>
<br>
Barbara<br>
PS. I am attaching a spreadsheet in which I have attempted to record
the signature sequence and the anomalies.<br>
