John Dalton to Faraday   29 July 1840

Manchester, | 29th of July, 1840. -

Dear Friend,

I sent up two papers on [sic] 1839 (I think it was in May) on the Phosphates & the Arseniates1.

You delivered them the 20 of June, 1839, as I find by the Philosophical Magazine, Vol. 15, page 3372 [sic], for which you have my thanks; there were in all 10 papers on various subjects read at the Society.

As I think it will not be published, there being several papers read since, in the Philosophical Transactions, I would thank [you] to take the trouble to send me down the articles of the Phosphates & the Arseniates; it follows as matter of course that they should be reclaimed by the Author.

I have an imperfect copy of them; but I should wish to send the originals, as I have taken great pains with them.

I have the following Essays by me:

"On the mixture of sulp[h]ate of Magnesia & Biophosphate of Soda: no Magnesia in it."3

"On the Acid, Base & Water in Salts4: they are united in atomic proportions; no 1/2 or 1/4 or 1/8 parts of atoms of water that I have found as yet."

"On the Microcosmic Salt 5.

It is my present intention to publish them together with the Phosphates & Arseniates, as a sequel to my Chemistry6.

I am with great respect | Yours faithfully | John Dalton

"On the Phosphates" (RS MS AP 23.5) and "Arseniates" (RS MS AP 23.6). Both are endorsed "Recd 18 April 1839" and "See Dr Faraday's letter". This letter has not been found. The Committee of Papers of the Royal Society archived these papers on 17 October 1839, RS MS CMB 90c, p.198. Dalton was offended by this rejection as he made clear in Dalton (1840a), 21.
2
Phil.Mag., 1839, 15: 327 records with very short abstracts that Dalton's "On the Phosphates" and "On the Arseniates" were read to the Royal Society on 20 June 1839. These were subsequently published as Dalton (1840a).

This forms part of [Dalton] [1840b], 3-5.
4
This forms part of ibid., 6-14.
5
[Dalton] [1840b].
6
Dalton (1808-27). This is what happened in some copies at least.
