Referee's report by Geoffrey Ingram Taylor, on a paper 'Natural convection in liquids' by O A Saunders Sectional Committee: Physics Recommended for publication in the 'Proceedings of the Royal Society of London'. Considers some of the concluding statements to be untrue. Found the author's inclusion of 'huge' diagrams to be an inconvenience which delayed his reporting on the paper.
