Referee's report by John Henry Poynting, on a paper 'The role of diffucion in the catalysis of hydrogen peroxide by colloidal platinum' by George Senter Sectional Committee: not stated. He has written to Sand asking if he would wish to say anything if Senter's paper were published and Sand replied that he would not. Encloses Sand's letter [not attached] from which he can see Sand has extracted some meaning from the paper, and has thus been more successful than Poynting himself. Poynting thinks it a 'most woolly' production but as it contains a new point, according to Sand, Poynting supposes it ought to be published. [Published in Proceedings of the Royal Society A, 1904].
