Poincaré à Ames
I congratulate myself more and more in having taken the initiative in
bringing to Paris Mr. Pender. The results already obtained do not
allow any further doubt that this question, so controverted, is going
to be cleared up, most probably according to the views of Mr. Rowland.
The experiments of Mr. Pender have been repeated successfully besides
they have operated with two disks nus ... and the results have
been still more positive .... There remain still further questions
to be settled from which it is necessary that Mr. Pender should remain
somewhat longer in Paris and it would be very desirable that he should
bring before the Society of Physics, after Easter, in connection with
Mr. Cremieu, the results obtained.
If you can get from the Carnegie
Institution a further subvention allowing this prolongation of
Mr. Pender's absence all the friends of science will be very grateful.

Notes:
The document bears a Carnegie Institution
date stamp, "MAR 28 1903", and a pencilled
annotation, "From DCG", suggesting that the letter was transmitted to
Daniel Coit Gilman. Gilman (1831-1908) served as the first
President of Johns Hopkins University from 1876 to 1891, and as
President of the Carnegie Institution of Washington from 1902 to
1904. The typed transcription begins with the sentence:
"Substance of a letter from Professor Poincaré to Prof. Ames."
On these experiments see
the correspondence with Victor Crémieu (§ cremieu).
Crémieu and Harold Pender (§ pender)
presented the results of
their collaboration on 17.04.1903 to the Société française
de physique, confirming those obtained earlier by Pender
[Pender et Crémieu, 1903].
