1The best and most accessible English account of Servetus based on original documents is that by Sir William Osler, Michael Servetus (Oxford University Press, 1909, and Johns Hopkins Hospital Bulletin for January, 1910). It was read at the Johns Hopkins Hospital Historical Club on May 10, 1909, and at the Oxford Summer Extension Course on August 10, 1909. The present writer has treated the subject of Servetus in Contributions to Medical and Biological Research, Dedicated to Sir William Osler, in Honour of his Seventieth Birthday, N.Y., 1919, ii, 767-777, espec. 772f. A serious mistake in the printing may be corrected here: the Latin note printed in the text on p. 774 is of course Murr's own note to “illato*” and should have followed the line ending “1790 8 mai.” Also the words “a. 1786... illato,” added later by Murr, should follow “exemplo” I find that Murr's rare reprint of the “Christianismi Restitutio” of Servetus was listed for the first and only time in the second Mess-Katalog for 1791 (“Allgemeines Verzeichniss der Bücher welche in der Frankfurter und Leipziger Michaelismesse des 1791 Jahres... neu gedruckt oder... wieder aufgelegt worden sind... ” Leipzig, Weidmann, p. 259, under “Fertig gewordene Schriften”) as “Serveti, Mich., Christianismi Restitutio, 8 maj., MDLIII,” without stating that it was a reprint, and without naming any place, printer, publisher or agent. Probably the date of the Mess-Katalog accounts for the similar wrong date given by the Jena Allg. Lit. Ztg. for November 20, 1792, mentioned in my “Servetus Notes,” p. 774. Both ignored the minute “1790” at the end.
