Last letter to JH was private [see GA's 1845-4-1].
Received reply from Karl Kreil in letter from Count Senftenberg, who owns private magnetic and meteorological observatory east of Prague run by Kreil's former assistant. ES asks JH to write letter to Clemens von Metternich, as requested by Senftenberg. High regard for Kreil's work.
Provides the best values available for dispersion and separation, which will allow GA to calculate what he needs [see GA's 1845-4-4].
Wants information on dispersion/separation of light in plate or crown glass.
Regarding the deed for CB's brother-in-law. Is reading G. W. Leibniz's metaphysical works.
