LettreNorman Lockyer à Henri Poincaré, 12 février 1892

Feb 12 [1892]
South Kensington — Science and Art Department1

Dear Professor Poincaré,

I have not had an opportunity of inquiring lately after Sylvester’s health.2 The last time I saw him he looked very ill & told me he was arranging a consultation as he was convinced there was something very wrong.

When I hear again I will let you know.

I shall be delighted to print your letter.3

Very sincerely yours,

Norman Lockyer

Apparat critique 

  1. The Science and Art Department of the British government was a sub-division of the Education Department, with oversight of the Royal College of Science, where Lockyer was professor of astronomical physics and director of the solar physics laboratory. In 1907, the Royal College of Science became part of the Imperial College of Science and Technology Gay (2007).↩︎

  2. Lockyer had recently written Poincaré that J.J. Sylvester was ill ( Lockyer à Poincaré, 1892-01-26), apparently in response to a query from Poincaré. It seems that Poincaré then asked Lockyer for details of Sylvester’s condition.↩︎

  3. See Poincaré (1892), published 03.03.1892, and reedited in Walter, ed. (2007), Poincaré à Tait, 1892-02-24). Poincaré reacted to Peter Guthrie Tait’s critical review of his Sorbonne lectures on thermodynamics Tait (1892), reedited in Walter, ed., (2007).↩︎
