Sir John Herschel
To:
Jacques Babinet
Date:
[4 February 1862]
Source of text:

Sir John Herschel
To:
Jacques Babinet
Date:
[24 February 1862]
Source of text:
RS:HS 19.148
Summary:

JB's solution to torsion thread arrangement is simpler and more ingenious than JH's. Enquires about details of gravimetric balance. Pendulum measurements. Density of continents. Clarification of JH's privileges as foreign associate of Institute. Death of J. B. Biot.

Herschel8349

From:
Sir John Herschel
To:
Jacques Babinet
Date:
[19 February 1863]
Source of text:
RS:HS 19.151 (C: RS:HS 24.10)
Summary:

Suggestions on improving JB's gravimetric balance, constructed on principle of 'Bifilar suspension.' Refers to 1861 report of similar invention by J. A. Brown and another article on this topic.

Herschel8356

From:
Sir John Herschel
To:
Jacques Babinet
Date:
[5 March 1867]
Source of text:
RS:HS 19.158
Summary:

No mention of Emmanuel Liais's L'espace céleste in English journals. Contact London publishers to find translator for it. Alexander Herschel is now professor of natural philosophy at Andersonian Institution in Glasgow. Hopes JB's elegant method of measuring gravity by torsion will not die before being put into practice.

To:
Sir John Herschel
Date:
[22 February 1862]
Source of text:
RS:HS 19.202
Summary:

Describes procedures, apparatus, and calculations for determining the static gravity of the earth. Thanks JH for some of his writings, and comments that JH, like Newton, has discovered the mind of the Creator and passed this on to humanity.
