Herschel11646

From:
James McCullagh
To:
Sir John Herschel
Date:
[2 October 1846]
Source of text:
RS:HS 12.11
Summary:

Has been on the Continent, which accounts for the delay replying to JH's letter of June. Regrets he cannot give an answer to JH's queries regarding the constitution of the ether. Fears his hypothesis on the density of the ether is not clear as it has misled JH. Has read Michael Faraday's papers with eagerness.
