This neglect is no doubt largely accounted for by the
advantage for practical purposes of tables computed to

For the completeness of the Catalogue I am very
largely indebted to the Librarians of the numerous
libraries referred to. I most cordially thank them for
their kind assistance, and for the very great amount of
trouble they have taken to supply me with the information
I was in search of. To Mr Davidson Walker my
hearty thanks are also due for assistance in collating
works in London libraries.
I
have only to add that any communications regarding
un-catalogued editions or works relating to Napier will
be gladly received.
