Letter from C.M Stubb, "Kingsmead", Selly Oak, Birmingham, to The Secretaries, Royal Society Encloses an account that has been sent to him in error [enclosure not present]. Informs that Dr Prideaux and himself received only 50 free authors' copies of their paper [A spectro-photometric comparison of the emissivity of solid and liquid gold at high temperatures with that of a full radiator] and believes the error may be owing to the Laboratory ordering 200 copies referred to in the erroneous account. June 1913
