I found in you last August a wonderful and providential help. Coming home to Lorraine for a few days, ill, and with my heart full of sorrow, I dreaded the shock which I should feel at the sight of the ruins and distress . . . and went away comforted and in good health. I was at the end of my tether, and unfortunately I am not religious. I longed to find some one who could help me, and meeting you by chance at my cousin's house you gave me the very help I sought. I can now work in a new spirit, I suggest to my unconscious to re-establish my physical equilibrium, and I do not doubt that I shall regain my former good health. A very noticeable improvement has already shown itself, and you will better understand my gratitude when I tell you that, suffering from diabetes with a renal complication, I have had several attacks of glaucoma, but my eyes are now recovering their suppleness. Since then my sight has become almost normal, and my general health has much improved. Mlle. Th----, _Professor at the Young Ladies' College at Ch----, Jan.,_ 1920. *** I read my thesis with success, and was awarded the highest mark and the congratulations of the jury. Of all these "honours" a large share belongs to you, and I do not forget it. I only regretted that you were not present to hear your name referred to with warm and sympathetic interest by the distinguished Jury. You can consider that the doors of the University have been flung wide open to your teaching. Do not thank me for it, for I owe you far more than you can owe me. Ch. Baudouin, _Professor at the Institut. J.-J. Rousseau, Geneva._ *** . . . I admire your courageousness, and am quite sure that it will help to turn many friends into a useful and intelligent direction. I confess that I have personally benefited by your teaching, and have made my patients do so too. At the Nursing Home we try to apply your method collectively, and have already obtained visible results in this way. Docteur Berillon, _Paris, March,_ 1920. *** . . . I have received your kind letter as well as your very interesting lecture. I am glad to see that you make a rational connection between hetero and autosuggestion, and I note particularly the passage in which you say that the will must not intervene in autosuggestion. That is what a great number of professors of autosuggestion, unfortunately including a large number of medical men, do not realize at all. I also think that an absolute distinction should be established between autosuggestion and the training of the will. Docteur Van Velsen, _Brussels, March,_ 1920. ***
