Thanks for his paper on amalgams. Regarding the amalgam of iron, he pointed it out many years ago in his Bakerian lecture. Would be interesting to experiment further with iron in solution of mercury.

The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.

Received four issues of GQ's Moniteur Scientifique. Saw mention in No. 163 of JH's proposed modification to British system of weights and measures. JH's paper on this topic is now before Astronomical Society of Leeds.
Comments on the ease of calculation in geodesy in JH's version of the English system of units, and asks GA for some clarifications as JH prepares the seventh edition of his Outlines Astr.
Accepts invitation to dine with ES. Working on sixth edition of Outlines Astr. Has sent argument against converting to metric system to Leeds.
Comments on the possibility of employment in India for GA's son, Hubert.
Thanks GA for receipt of some Royal Observatory publications; is still pushing the British metrical standard based on the length of the earth's polar axis [see JH's 1860-3-2].
JH wants to avoid using the meter in England; asks GA for the results of A. R. Clarke's calculations on the figure of the earth [see GA's 1863-10-7].
Thanks for sending him his memoir on the Figure of the Earth. Comments on this. His son John would find a copy of this memoir of great assistance in his work in India; would he send him one.
Comments on Greek fire lead JH into a variety of recollections.
