Copy letter from Robert William Frederick Harrison, to Dr Sidney Frederic Harmer, Fellow of the Royal Society Harrison has looked up the matter of Mr Kirkpatrick's paper and finds that the bill for the plates has been presented here and paid - a matter of £9.8. He knows nothing of any further bill connected with the reproductions of the drawings. The Royal Society is not responsible for the preparation of drawings in a style suitable for reproduction, that lies with the authors. 4 March 1911
