Copy letter from Robert William Frederick Harrison to J W Bispham, MA, 227 Lordship Lane, East Dulwich, SE 'Dear Sir, In answer to your letter of the 6th inst. - the Proceedings [of the Royal Society] (No. A 550) containing your paper on Glow Discharges is published and we are posting you a copy. The price is, as you say, 2/6 and I shall be obliged if you will send a postal order for that amount. The 50 copies of the paper should certainly be in your hands by now, as the No. containing it was issued a fortnight or so ago. If you have still not received them, pray let me know.' 8 February 1909
