Copy letter from Herbert Rix, to the Director, Museo de la Plata, La Plata, Argentine Republic Rix apologises that their letter of 20 November has been unanswered for so long, but explains that the presure of Committee work had prevented the Library Committee from meeting until recently. He is now, however, able to inform them that their request to add 'Philosophical Transactions of the Royal Society' to their grant has been agreed to, and that in future the biological section will be sent regularly by post. 31 July 1894
