Copy letter from Robert William Frederick Harrison, to Messrs Harrison & Sons, St Martin's Lane, W.C. 'Gentlemen, I am directed to call your particular attention to the serious delay which has occurred in setting up the paper for the "Phil. Trans," ['Philosophical Transactions of the Royal Society'] by Mr Walter Heape, proof of which was delivered here only two days ago, the copy having been sent to you on the 19th December. I shall be glad to hear what explanation you have to offer and to have some assurance that the cause, or causes, whatever they may be, of this delay will not operate in future. I am, yours faithfully, Robt Harrison Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 29 January 1897
