Referee's report by George Clarke Simpson, on a paper 'Instability of fluids heated from below' by Krishna Chandra Sectional committee: Physics Recommended for publication, as the subject matter is interesting. However, it requires a complete re-write. It is 'one of the worst written papers' he has ever had to referee and the paper shouldn't have been presented to The Royal Society in such a crude form. The English used is often not understandable and the arrangement of the paper is hap-hazard. Has attached notes to help the author re-write the paper. [Published in Proceedings of the Royal Society A, 1938]. Endorsed on verso as received 29 July 1937. 27 July 1937
