Copy letter from Robert William Frederick Harrison, to Professor Karl Pearson, Fellow of the Royal Society The Homotyposis paper about which Pearson enquires should be out next week. The paper is a heavy one and though communicated 12 months ago, there was a good deal of discussion on the paper before it was decided to print it, as Pearson knows. Today they are sending Pearson proofs of the 'Errors of Judgment' paper. 29 October 1901
