[Royal Institution of Great Britain] | Thursday 3rd Nov
My dear Stokes,
Some days ago I wrote2 to inform you that I had succeeded in making platinum red hot with obscure rays. Circumstances which have since occurred3 cause me to ask you to consider that note unwritten.
Yours truly | John Tyndall
RI MS JT/1/T/1428
RI MS JT/1/TYP/4/1479
[1864]: the year is given by reference to letter 2162.
I wrote: letter 2162.
Circumstances which have since occurred: namely, the arrival of letter 2165 from Akin. Akin had suggested that Tyndall had acted outside the bounds of gentlemanly propriety. See also letters 1925, 2075, 2076, 2079, 2114, 2162, 2167, 2170, 2173, 2182, 2183, 2190, 2197, 2198, 2201, 2204, 2208, 2214, and letters in volume 9.
