Sir John Herschel
Date:
[24 April 1816]
Source of text:
RS:HS 18.36
Summary:

Suggests changes for JH's paper on Swedish felspar submitted to Geological Society. Confusion between this and other silicates. Compares JH's analysis to that of Wilhelm Hisinger and others.

Henry Warburton
To:
Sir John Herschel
Date:
[3 June 1816]
Source of text:
RS:HS 18.37
Summary:

Discussed JH's proposed felspar paper [see HW's 1816-4-24] with W. H. Wollaston. Suggests using Wollaston's and [recently deceased Smithson] Tennant's unpublished method to test for alkalis and give Tennant credit for it. James Smithson first coined term 'silicate'.

Herschel7835

From:
Henry Warburton
To:
Sir John Herschel
Date:
[19 October 1847]
Source of text:
RS:HS 18.39
Summary:

Sends copy of HW's paper on combinations of 'Plural Elements,' printed in Transactions of Cambridge Philosophical Society, based on the method of continued subtraction suggested by Augustus De Morgan. Shows solution for Bernoulli's fifth number.

Herschel7836

From:
Henry Warburton
To:
Sir John Herschel
Date:
[14 November 1847]
Source of text:
RS:HS 18.40
Summary:

Close to finding expeditious, symmetric method for computing Bernoulli's numbers. Resolves four formulas that HW sent to JH earlier today.

Herschel7837

From:
Henry Warburton
To:
Sir John Herschel
Date:
[22 November 1847]
Source of text:
RS:HS 18.41
Summary:

Thanks for comments on HW's paper and work on properties of Bernoulli's numbers. Claims HW's method of continued subtraction is convenient process for determining numerical coefficients. Found error, long perpetuated in literature, regarding Bernoulli's 13th number. Offers correct solution.

Sir John Herschel
Date:
[29 November 1847]
Source of text:

From:
Henry Warburton
To:
Sir John Herschel
Date:
[5 December 1847]
Source of text:
RS:HS 18.46
Summary:

Error in Leonhard Euler's value for Bernoulli's 21st number. Promotes HW's method of continued subtraction as a reliable means of proving accuracy of values for higher Bernoulli numbers.

Herschel7843

From:
Henry Warburton
To:
Sir John Herschel
Date:
[13 December 1847]
Source of text:
RS:HS 18.47
Summary:

Destroy all HW's letters claiming errors in Leonhard Euler's values for Bernoulli's numbers. Mr. Hensley of Trinity College found weakness in HW's continued subtraction method. Clarifies symbols HW used to represent P. S. Laplace's expressions of Bernoulli's numbers.

To:
Sir John Herschel
Date:
[14 December 1847]
Source of text:
RS:HS 18.48
Summary:

Continues explicating P. S. Laplace's formula for determining Bernoulli's numbers. Concerned that JH sees HW claiming too much for HW's continued subtraction method.
