Copy letter from Robert William Frederick Harrison, to [Walter] Heape, [Fellow of the Royal Society] Is very sorry that he has had to write again about his change of address. The printers have been told twice about this, and they have seemingly ignored it. They have been written to demanding an explanation, and to ensure that despatches reach him in the future. Officially expresses regret that he should have been put through this inconvenience. 25 July 1913
