Referee's report by Horace Lamb, on a paper 'A method of finding the conductivity for heat' by Charles Niven Sectional Committee: Mathematics He would have no hesitation in recommending the paper for the Proceedings; the real question is whether the experimental method in part one is a valuable addition to known methods. He has no modifications to suggest and thinks all the illustrations should be given. The mathematical problems discussed in the second part of the paper are interesting and certainly worthy of record; but he does not think that of themselves they could claim a place in Philosophical Transactions. It might be worth including a rough estimate of the limits of error in a formula related to the steady states in a cylinder of infinite radius in part one of the paper.
