What both I and Vieweg meant was that the proposed amount of 4 or 3 pence would be for Vieweg and me together, not for each individually. So if per booklet 4 pence is paid for both of us, then we are completely satisfied. For your readiness in the Freundlich and Schlick matter I thank you cordially. I have decided, however, to write to the publishers involved myself, so that you do not need to worry about this business anymore. The article for Nature is almost finished, but it has unfortunately become so long that I very much doubt whether it could appear in Nature. Should this not be the case, we could then perhaps find another publication means. I enclose a copy of the statutes of “Clarté” for you. Our German wing is still not ready yet. With best regards, I am yours. 276. To Kornél Loewy (-Lánczos) Berlin, 22 January 1920 Esteemed Colleague, I studied your paper as far as my present overload allowed. I believe I may say this much: this does involve competent and original brainwork, on the basis of which a doctorate should be obtainable. I myself do not belong to a university and therefore cannot come under consideration for a practical completion of the matter. I personally have little theoretical experience in the field of quaternions and presently hold the view that one gets by very well with the simple tensor expres- sion. But I am readily open to correction. I have not been able to form a definite opinion on the question of whether electrons should be construed as singular points or as singularity-free solutions to differential equations. It is known to you, of course, that in framing a theory of singularities one encounters the obstacle that the energy integral diverges to infinity at the transition to a point-shaped electron. (Fi- niteness of the electron’s mass.) I gladly accept the honorable dedication. With great respect.
