rtificialium rerum scientia_, Wuerzburg, 1657, 4to, with
editions at Bamberg in 1671, and at Frankfort in 1677. Gaspard Schott
(Koenigshofen 1608, Wuerzburg 1666) was a physicist and mathematician,
devoting most of his attention to the curiosities of his sciences. His type
of mind must have appealed to De Morgan.

naturalis, tum geometrica_, etc., 1608.--_Consideratio nova in opusculum

[80] Melchior Adam, who died at Heidelberg in 1622, wrote a collection of
biographies which was published at Heidelberg and Frankfort from 1615 to
1620.

[81] Born at Baden in 1524; died at Basel in 1583. The Erastians were
related to the Zwinglians, and opposed all power of excommunication and the
infliction of penalties by a church.

[82] See Acts xii. 20.

[83] Theodore de Bese, a French theologian; born at Vezelay, in Burgundy,
in 1519; died at Geneva, in 1605.

[84] Dr. Robert Lee (1804-1868) had some celebrity in De Morgan's time
through his attempt to introduce music and written prayers into the service
of the Scotch Presbyterian church.

[85] Born at Veringen, Hohenzollern, in 1512; died at Roeteln in 1564.

[86] Born at Kinnairdie, Bannfshire, in 1661; died at London in 1708. His
_Astronomiae Physicae et Geometriae Elementa_, Oxford, 1702, was an
influential work.

[87] The title was carelessly copied by De Morgan, not an unusual thing in
his case. The original reads: A Plaine Discovery, of the whole Revelation
of S. Iohn: set downe in two treatises ... set foorth by John Napier L. of
Marchiston ... whereunto are annexed, certaine Oracles of Sibylla ...
London ... 1611.

[88] I have not seen the first edition, but it seems to have appeared in
Edinburgh, in 1593, with a second edition there in 1594. The 1611 edition
was the third.

[89] It seems rather certain that Napier felt his theological work of
greater importance than that in logarithms. He was born at Merchiston, near
(now a part of) Edinburgh, in 1550, and died there in 1617, three years
after the appearance of his _Mirifici logarithmorum canonis descriptio_.

[90] Followed, in the third edition, from which he quotes, by a comma.

[91] There was an edition published at Stettin in 1633. An English
translation by P. F. Mottelay appeared at London in 1893. Gilbert
(1540-1603) was physician to Queen Elizabeth and President of the College
