Copy letter from Herbert Rix, to Monsieur le Professeur P A Sacardo, R Orto Botanico, Padova 'Dear Sir, The "Catalogue of Scientific Papers" which was formerly published at the expense of the Government, is now published by a private firm, and the Royal Society has not, therefore, the privilege of distributing the large number of copies which they formerly had. I am to say that all we can now do is to refer you to Messrs Clay & Sons, Ave Maria Lane, London. I am, yours truly, Herbert Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 10 January 1894
