Letter from Charles Perez, Faculte des Sciences, Sorbonne, Paris, to the Secretary of the Royal Society He informs his correspondent that he has succeeded Yves Delage as Director of the Roscoff Station. The Society has been a subscriber to a table at Roscoff and he considers that the death of Professor Delage will make no difference to these arrangements. He hopes that the Royal Society will continue its support and its annual subvention and asks that this be confirmed. Pending the response, he notes that the Society's table will be occupied by the son of J. Arthur Thomson, if that idea is agreeable. 14 May 1921
