Copy letter from [John William] Lubbock, Treasurer of the Royal Society; to [Joseph] Sylvester, University of Virginia, United States Gives thanks for the positive recollection of Lubbock in his paper. States however that the paper is obscure. Asks for the paper to be written fully, taking in many more steps, referencing other papers where a known subject is being discussed and asking for it to be legible. 8 April 1842
