Copy letter from Herbert Rix, to the Secretary, Furstlich Jablonowski'sche Gesellschaft, Leipzig, Germany 'Dear Sir, We have received from you two numbers of your "Preisschriften", namely, No. XII. of the "Mathematisch-naturwissenschaftliche Section"and No. XIX of the "Historisch-nationalokonomische Section". 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.-nationalokonom. Section" from your despatches to us. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 31 March 1896
