Letter from E J Allen, Director and Secretary to Council, Marine Biological Assocaition of the United Kingdom, The Laboratory, Citadel Hill, Plymouth, to [Francis Alexander] Towle 'Dear Mr. Towle, In response to your letter I have pleasure in enclosing cheque for £45, bring my share of the cost of the plates illustrating the paper on Procerastea. I think the plates have come out very well indeed, and as far as my share of the expense goes I feel that it has been quite worth it. Yours faithfully, E J Allen'. 22 October 1921
