Comments on analytic symbolism in mathematics.
Corrections to reports in 12 Mar. 1866 issue of Les Mondes regarding ecclesiastical titles in England, William Whewell's career, and W. T. Brande's role at Royal Mint. Also, English do not eat cats; 'catsup' is made of vegetables. Nor was JH's daughter [Maria Sophia] ever acquainted with late [Ludovico] Calandrelli.
FW's suggestion to collect William Herschel's published works into one volume was considered earlier, but publishers found it not profitable. All works except two are in R.S.P.T., 1780-1818. [Letter continues 22 Mar.:] JH almost completed identifying and assembling all of WH's double stars and micrometrical measures. Thanks for calling attention to 'unpublished series of 400 'Guages [sic] ('hausters')" noticed by [Maximilian Weisse]. JH was not aware of these. [Letter continues 23 Mar.:] Does not approve of FW's suggestion to request subscriptions to fund collection of WH's works. [Note by copyist: List of differences between original letter and copy.] [Unknown annotation: 'Original in No. 2 Corresp. Tin box B.8.']
Comments further on Ernst Klinkerfüss's work [see JH's 1866-2-28]; on the behavior of light emitted by an electric spark.
Is trying to assist in finding someone to review a book [The Heavens] by [Amédée] Guillemin.
Thinks William Whewell's excitement may be a 'precursor to exhaustion.' The hope of recovery is very slight. JH is interested in Whewell's article on Plato.
Thanks WS for communicating the events of William Whewell's last days.
Describes experiment involving viewing spectrum of a light flash as it advances and recedes. [Marked 'not sent on further consideration.']
Agrees to WJ's request to make use of an earlier letter of JH's [see WJ's 1866-3-7].
Will subscribe to HS's work as requested [see HS's 1860-3-5], but dissents 'from very large portions' of HS's views. Especially objects to HS's adoption of the 'Shibboleth of the Hegel & Schelling School of German Philosophy—"the Absolute."' [This letter misdated; correct date: 1860-3-17.]
