Herschel3443

From:
Sir John Herschel
To:
John Tyndall
Date:
[23 October 1870]
Source of text:
RI 459 (draft : RS:HS 17.409a; C: RS:HS 24.336; C: RI 573-4)
Summary:

Thanks for paper on action of rays 'of high refrangibility' on gases and vapors. Attempts to understand reflection of wave motion on particles with diameters 'incomparably smaller' than length of wave.

Herschel3524

From:
Sir John Herschel
To:
John Tyndall
Date:
[28 May 1866]
Source of text:
RS:HS 24.157 (C: RI 540)
Summary:

Thanks for note [see JT's 1866-5-26] on improvement of the lecturing style of JH's son [Alexander]. JH's son has studied lecture's subject deeply and loves science; JH hopes will be physics professor at a 'considerable institution.'

Herschel3526

From:
Sir John Herschel
To:
John Tyndall
Date:
[26 November 1868]
Source of text:
RS:HS 24.241 (C: RI 547-8)
Summary:

Thanks for paper on action of solar and electric light on vapors, which should give JT further insight into blue color of sky and polarization of skylight. Comments on the latter. JH's son [Alexander] is working hard at Glasgow.

Herschel3535

From:
Sir John Herschel
To:
John Tyndall
Date:
[2 December 1868]
Source of text:
RS:HS 17.405b (C: 24.242; C: RI 553-4)
Summary:

Thinks JT's work on polarization will lead to remarkable discovery. Discusses production of rainbow, parallels to Isaac Newton's explanation of black spot on a soap bubble, and problems in JT's undulatory theory explanation of reflection. In JT's experiments, what are nebulous particles produced by light in gas or vapor?

Herschel3537

From:
Sir John Herschel
To:
John Tyndall
Date:
[14 December 1868]
Source of text:
RS:HS 24.243 (C: RI 557-8)
Summary:

Thanks for paper verifying JH's prediction that explanation of blue sky color carries with it that of polarization of skylight. Involves ultimate link between chemical and analytical dynamics. Notes that 'neutral points' in sky polarization have yet to be explained; offers tentative explanation based on clues in JT's work.

Herschel3538

From:
Sir John Herschel
To:
John Tyndall
Date:
[28 May 1869]
Source of text:
RS:HS 17.406a (C: RI 559-60 & RS:HS 24:260)
Summary:

Thanks for paper on comets. Offers questions, problems to be resolved, particularly on termination of comet.

Herschel3542

From:
Sir John Herschel
To:
John Tyndall
Date:
[16 November 1864]
Source of text:
RS:HS 17.396 (C: RI 532 & RS:HS 24.68))
Summary:

Surprised that JT cannot obtain heat spots [see JT's 1864-11-14]. Describes glasses and lenses used.

Herschel3562

From:
Sir John Herschel
To:
John Tyndall
Date:
[15 March 1863]
Source of text:
RS:HS 24.14 (C: RI 522)
Summary:

Thanks for lectures on heat motion theory and radiation through earth's atmosphere, and for brochure on 'conformation' of the Alps. Asks about upcoming lecture of JH's son [Alexander].

Herschel3563

From:
Sir John Herschel
To:
John Tyndall
Date:
[18 July 1864]
Source of text:
RS:HS 17.393b (C: 24.48; C: RI 524-7)
Summary:

Thanks for and comments on papers on scientific history and molecular physics, particularly on a magnetic experiment and on dynamical efficiency of coal relative to motion theory of light and heat. Comments on nature of heat, 'vis viva.' Deplores laxity with which physicists use and confuse terms 'force,' 'motion,' and 'energy.'

Herschel3567

From:
Sir John Herschel
To:
John Tyndall
Date:
[17 March 1857]
Source of text:
RS:HS 17.386
Summary:

Thanks for lecture on glacier cleavage. Wonders how 'regelation' occurs when two masses of ice at 32° are placed in contact.

Herschel3578

From:
Sir John Herschel
To:
John Tyndall
Date:
[22 November 1861]
Source of text:
RS:HS 23.348 (C: RI 512-13)
Summary:

Does not believe surface of moon can radiate cold; perhaps new moon can. Explains this geometrically.

Herschel8359

From:
Sir John Herschel
To:
John Tyndall
Date:
[13 December 1868]
Source of text:
RS:HS 19.160b
Summary:

JT's paper on polarization of sky light suggests that neutral points are functions of cloud density. This verifies JH's earlier explanation of blue sky color. Incomplete polarization. Cause of blue color in water. Corrects note on W. A. Miller's observations of rainbows.
