Butler’s reply to EK is a renewed attack on CD. Urges EK not to answer it. His last letter contains everything necessary. Asks EK for dates of CD’s letter asking EK’s permission to publish a translation of his article [on Erasmus Darwin] and of the letter in which he told EK that Butler’s book had been advertised.

CD thanks him for his congratulations and for details of letters, which he will keep with the Butlerian documents.

FD is happy for his lecture to be republished in Kosmos.
