1 Royal Institution, Journals of Thomas Archer Hirst (hereafter cited as Hirst Journals), vol. iv, fol. 1702. I wish to express my thanks to the authorities of the Royal Institution for permission to consult and quote from materials in their possession, and to the Librarian, Mr. Stallybrass, for his helpful co-operation. See also Hirst's minutes of the meeting, as quoted in SirFrankland, Edward, Sketches from the Life of Edward Frankland (London, 1902), 150. Research for this study of the X Club was greatly facilitated by financial assistance from the Graduate School and the McMillan Fund of the University of Minnesota.

6 For insight into the nature and activities of the Lazzaroni, consult the following biographies: Dupree, A. Hunter, Asa Gray (Cambridge, Mass., 1959), and Lurie, Edward, Louis Agassiz (Chicago, 1960). Understandably, the latter is more full in its discussion of the Lazzaroni, since Agassiz was one of its leading members, whereas Gray was excluded from the group. See also Dupree, A. Hunter, “The Founding of the National Academy of Sciences—a Reinterpretation”, Proceedings of the American Philosophical Society, ci (1957), 434–440.

(3), ii, 139) more fully described The Reader as a “weekly paper (of The Spectator form) predominantly literary, and in a smaller degree scientific, which had been founded a year or two before by Mr. T. Hughes, Q.C., Mr. Ludlow, and others who, dissatisfied with existing papers of the class, were desirous of having one which should be candid and impartial in its criticisms, and liberal in its views of affairs—not political affairs so much as social affairs”.

41 Some of Tyndall's vigorous writings on the subject were published in 1887 by William Blackwood and Sons in a one-penny pamphlet entitled, “Mr. Gladstone and Home Rule”. In Tyndall's urgent language, one can almost sense the memory of his martyred distant relative, William Tyndale, playing a contributory role. For some discussion of Tyndall's Unionist views, see Eve, and Creasey, , op. cit. (40), 17, 248, 264–267, 277–278.
