\brief{Otto Neurath an Rudolf Carnap und Charles W. Morris, 23. März 1944}{März 1944}\labelcn{1944-03-23-Neurath-an-Carnap-Morris} \anrede{Dear co-editors,} \haupttext{ I have the great pleasure to inform you, that Lancelot Hogben will write for our Encyclopedia: FOUNDATIONS OF BIOLOGY, VOLUME I, Monograph 9. The monograph will be of about 9000 words. He promised to write it before December 44. Let us hope he will finish it in good time. He is at the moment in a responsible position in the war office and therefore very busy with his activities. I got the galley proofs of my monograph and shall return them very quickly. Since Frank, Freundlich and others are at work, too, we shall finish the first two volumes within a reasonable time -- I hope so. With the best wishes } \grussformel{Ever yours\\\editor{Otto Neurath}} \ebericht{Brief, Dsl., 1 Seite, \href{https://doi.org/10.48666/847145}{ON 223}; Briefkopf: msl. \original{23\textsuperscript{rd} March, 44}, am Briefende hsl. \original{Morris\,/\,Carnap\,/\,(Copy: Hogben)}; ohne Signatur.}
