Referee's report by Augustus Edward Hough Love, on a paper 'The stability of the pear-shaped figure of equilibrium of a rotating mass of liquid' by George Howard Darwin Sectional Committee: Mathematics Recommended for publication in Philosophical Transactions, in full. He has no modifications to suggest and thinks all the illustrations should be reproduced. The paper is an important contribution to a very difficult subject. It is the outcome of a concentrated effort by Professor Darwin and Monsieur Poincaré to attain to fuller knowledge of the problem of stability of rotating masses of liquids.
