BR has now read Jørgensen's Treatise of Formal Logic (Russell's Library, nos. 1882-1884) and finds himself "naturally in practically complete agreement with your outlook." BR is "relieved to find that your views are so closely similar to those of Principia Mathematica". "I have since August 1914 practically abandoned the study of mathematical logic. In reading your book I began to feel that perhaps this had been a mistake. In case there should ever be another edition, I should be glad to let you have a note as to a few small misprints, especially as regards the use of dots."
