Copy letter from Herbert Rix, to the Secretary, Videnskabs-Selskab, Christiania, Norway 'Dear Sir, We received from you a few days since two volumes of your "Skrifter", namely "Mathematisk-naturvidenskabelig Klasse", 1894, and "Historisk-filosofisk Klasse", 1894. Owing to the rapidly decreasing available space in our Library, we are forced to confine our accessions to Natural Science, and, under these circumstances, I beg that you will in the future omit the Histor.-folis. Klasse of the "Skrifter" from your despatches to us. I am, yours faithfully, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 30 March 1896
