Referee's report by Andrew Crombie Ramsay, on a paper 'Volcanic energy: an attempt to develop its true origin and cosmical relations' by Robert Mallet Recommended for publication in Philosophical Transactions, as there is 'so much of novelty and value in the paper'. It should be edited by the author before publication, as there are a few mistakes in geology. Subject: Physics/Astronomy [Published in Philosophical Transactions, 1873]. 1872
