Catalogues of tables (separate) may be seen in tbo catalogue of the Royal Society's Library ; in Murhard's Bibl. Math.;' in Lalande's Bibl. Astron. (in virtue of the index); but there is nothing approach ing to even a moderately perfect catalogue.
In the preceding article wo have described, we believe, all the tables of no& whether in history or practice, so far as general tables of pure mathematics are concerned. We have omitted those which relate only to astronomy, life contingencies, or any other special application of mathematics. As the article stood in the' Penny Cyclopwdia,' we had brought forward about 318 tables, of which 221 had been taken from actual inspectio'n, and the remainder from various authorities, very few indeed from one only. In Lalande's Bibliographic Astronomique ' there are 208 tables mentioned, including astronomical ones. In the printed catalogue of the Royal Society's Library the entries under tables, of every sort, mathematics, astronomy, navigation, geography, meteorology, &c., are 536 in number, including from the merest tide table for one year up to tbo largest body of logarithms. And upon looking at the appearances which the different catalogues present, we do not find one in which 200, or even 100, tables of pure mathematics are mentioned as having undergone the actual inspection of the compiler.
In the present article we have given about 457 tables, of which 332 are from actual inspection. It would not, then, we suspect, be a very extensive undertaking to make as complete a list of tables of all kinds as can now be recovered; and the undertaker of it might expect to be able to verify about two out of three from inspection.
In the present article some additions have been made, both of tables and of facts alluding to tables already inserted, and several corrections. We have not made any effort to include all the tables of the last few years, preferring to direct our chief attention to the improvement of the antiquarian part of our task. To this end we have examined anew all the old tables which we could conveniently see. In reviewing our work, we find that we have sometimes spoken of the decinud places in a table, and sometimes of the radius to which it is constructed; but we do not mean that the old tables had decimal places, properly so called. We must also remind the reader that this article is not 6Mo /rap/tied; our affair is not with books as books, but with tables as tables. Accordingly, the descriptions of books are not fully given : and their contents, except so far as they are the tables spoken of, are wholly unnoticed.
