Letter from Vito Volterra, Via in Lucina 17, Rome, to Sir Joseph Larmor, Cambridge He gives thanks to Larmor for his kindness towards [Enrico] Persico during the time he spent at Cambridge. He also thanks Larmor for sourcing the issues of the London Mathematical Society Proceedings which he had missed. He sends a short note [not present] on a problem of mathematical biology. He would be grateful if this might be published in 'Nature'. Volterra hopes to come to England in the summer. 11 June 1926
