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"! 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?
