On a new series of equivalents or molecules' by Robert Angus Smith Recommended for publication in the Proceedings of the Royal Society of London. Refers to work of Saussure and Hunter [?]. Believes some of the results are an 'arithmetical coincidence', and some of the explanations are difficult to understand. Unless curtailed, the paper should not be published.
