Congratulates Sherrington on becoming President of the Royal Society. Has no regrets now that Sherrington did not come to Toronto (CSS had said he would have gone there had he been offered the Chair of Physiology). Has himself resigned chair of Research Council of Canada. To take up chair of biochemistry at McGill. Will be going in February with Mrs. Macullum to Peking. Sons engaged in production of arsenical products. Hopes Sherrington will occupy the presidency for at least ten years and that he will reach 'a hallowed old age, kindly, humerous, and thoughtful'.
