The addressee, Mr. Butler, is most likely R.A. Butler, Under-Secretary of State for India, 1932-37. (Russell's brother, Frank, had held the same position, 1929-31, under the Labour government.)

Extract:
"I should be very glad if you could come to a small meeting on Monday evening, the 21^st instant, at 8 pm, to meet the members of the India League Delegation on their return from India.

"We are inviting a few people who are interested in India to hear the Delegates talk of their interesting experiences and to have an opportunity of discussing personally with them the present situation out there.

"Mr and Mrs J. F. Horrabin have very kindly allowed us to hold this meeting in their house at 72, Gower Street, WC1."

[Annotation by India Office official:]
"The public meeting is to be on the 26^th, I think, and any public counterblast should be issued either at it or simultaneously or both. I agree that this private meeting would be no good for counterpropaganda, but it would be useful to have a spy there."
