Referee's report by George Udny Yule, on a paper 'On the mathematical foundations of theoretical statistics' by R A Fisher Sectional Committee: Mathematics Recommended for publication in the 'Philosophical Transactions of the Royal Society'. Suggests there should be a summary at the end. Hopes another referee will speak from the position of a mathematician, as the referee feels he can only speak from the view of a statistician.
