3-34-2. Norman Lockyer to H. Poincaré

Feb 12 [1892]

South Kensington — Science and Art Department11The 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, 35).

Dear Professor Poincaré,

I have not had an opportunity of inquiring lately after Sylvester’s health.22Lockyer had recently written Poincaré that J.J. Sylvester was ill (§ 3-34-1), apparently in response to a query from Poincaré. It seems that Poincaré then asked Lockyer for details of Sylvester’s condition. 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.33See Poincaré (1892), published 03.03.1892, and reedited in Walter, ed. (2007, § 2-55-1). Poincaré reacted to Peter Guthrie Tait’s critical review of his Sorbonne lectures on thermodynamics (Tait 1892, reedited in Walter, ed., 2007, § 2-62-2).

Very sincerely yours,

Norman Lockyer
