Letter from Joseph Barcroft, 13 Grange Road, Cambridge, to Francis Alexander Towle Thanking Towle for his letter and enclosures. It is not quite clear why Mr. Salomon wrote his letter, whether on his own initiative or in response to others. When Barcroft last saw Hardy he was going to write to the Foreign Office about the Peruvian Expedition and this letter might be the result. 28 July 1921
