I came across two letters by Raymond Holbrook Arnot (1874 - 1948) who was an attorney in Rochester, USA. Arnot was interested in history and was a president of the Rochester Historical Society. He was also interested in science and in the late 1890's was the president of the "Alfred Russel Wallace Scientific Club of Rochester", which Wallace was the Patron of! I had never heard about this club until I read these letters and I can't find out anything more about it. When Arnot wrote to Wallace in 1898 and 1899 the club had more than 50 members. I wonder what happened to it?
