Copy letter from Robert William Frederick Harrison to W [William] K [Kingdon] Spencer It is the practice of the Royal Society to obtain confidential opinions from its Fellows upon papers submitted to the Society for reading and publications. The Standing Orders, however, allow for a referee not to be a Fellow if there are special reasons. A paper has been received lately on a special branch of geology, and it is the opinion of the Chairman of the Sectional Committee and of the Biological Secretary of the Society have special reasons for appealing to a geologist outside the Society for an opinion upon it. In these circumstances Harrison is directed to ask Spencer to give the Society the benefit of his opinion. 27 June 1911
