Copy letter from Robert William Frederick Harrison to A [Arthur] E [Everett] Shipley, Fellow of the Royal Society 'Dear Mr Shipley, There will be no obligation to the Secretary of the Grouse Disease Inquiry distributing the twenty Soiree invitations placed at the disposal of the Commission, but it is against our practice to send out blank cards of invitations, so that I should be obliged if the Secretary would let me have a list of those to whom he proposes sending invitations in order before they are sent to him in the bulk for distribution, I understood that twenty was the total number of invitations to be allowed in connection with this exhibit.' 24 April 1908
