Thanks for letter and pamphlet on vivisection; explains that this was not covered in ARW's Wonderful Century because vivisection "is not specially connected with the 19th-Century". Proposes to call the enlarged edition "The century of new ideas in science and the arts …"; Phrenology and Hypnotism were [practically, ins] discoveries of the 19th Century; vivisection is "wholly bad" but in a different category of "evils" as does not take away personal freedom.
