8°. 16 pages.<br />
<strong>The</strong> above short Preface occupies <strong>the</strong> first page <strong>of</strong> a small tract <strong>of</strong><br />
sixteen pages, <strong>the</strong> remaining fifteen containing <strong>the</strong> natural numbers from<br />
I to 1000 with <strong>the</strong>ir <strong>logarithms</strong>, to base lo, to 14 places. <strong>The</strong> tract<br />
bears no author's name or place or date <strong>of</strong> publication, but <strong>the</strong> evidence<br />
which assigns it to Briggs, and fixes <strong>the</strong> place and date <strong>of</strong> its publication<br />
as, London, 1617, seems conclusive. <strong>The</strong> Table <strong>of</strong> Logarithms is <strong>the</strong><br />
first published to a base different from that employed by Napier.<br />
It is unnecessary here to refer to subsequent works on Logarithms <strong>of</strong><br />
a different kind from those originally published by Napier.<br />

Note.—In <strong>the</strong> foregoing Catalogue <strong>the</strong> only collections<br />
<strong>of</strong> Napier's<br />
works referred to are in public libraries. <strong>The</strong> largest single collection,<br />
however, is that in possession <strong>of</strong> Lord Napier and Ettrick.<br />
Besides <strong>the</strong><br />
editions more commonly met with, it embraces several not found in<br />
any <strong>of</strong> <strong>the</strong> public libraries <strong>of</strong> this country, as well as a copy <strong>of</strong> <strong>the</strong> rare<br />
'Ephemeris Motuum Ccelestium ad annum 1620,' which contains Kepler's<br />
letter <strong>of</strong> dedication to Napier, dated 27th July 1619.
