Has kept Mary Somerville's papers a little longer. If these papers are to be published they would require considerable revision.
A note to accompany the forwarding of a communication to GA.
Has no changes to make in JH's Admiralty Manual.
Thanks HS for response to and explains further JH's letter to John Tyndall regarding explanation of origin of geological slaty cleavage.
Success of C. P. Smyth's Teneriffe expedition pleases JH; anxious for declination of nebulae taken from high altitudes. Upset over G. J. Stoney's reproduction of JH's collimating telescope without giving him credit.
Thought that AD's last letter was supposed to be written in verse. Hopes his injury will soon improve. Does not recollect any habit of Humphry Davy rubbing his hands together. A professor, [G. J.?] Stoney, has re-invented JH's collimating telescope and not improved it.

Acknowledges receipt of a paper by [William] Pole, which JH will review.
Thinks that aluminum coating on telescope mirrors may work [see FK's 1856-10-9]; also suggests looking into flouric glass containing aluminum for lenses of low dispersion power.
Needs more time for reviewing Pole's paper [see JH's 1856-10-12].
Comments on the state of JH's health, color blindness, missing R.A.S. Notices, and decimal coinage.

Would be inclined to try a combination of cryolite and silex to obtain a glass. Comments on his process for decomposing alumina by cyanide of sodium. Sorry to see that FK uses the current forms of chemical notation.
Letter of introduction for the Drs. Hermann and Robert Schlagentweit, whose scientific interests parallel JF's.
