Letter from Charles Thomas Heycock, on his paper 'Complete freezing-point curves of binary alloys containing silver or copper, together with another metal' with Francis Henry Neville to the Secretary of the Royal Society The authors have read the referee's opinions but do not want to alter their interpretation of the results. Most of the referee's crticisms will be irrelevant when he reads the published paper. He is willing to discuss the paper with the referee. They are indebted to him for calling attention to an error in two of the diagrams. Subject: Chemistry [Published in Philosophical Transactions A, 1897]. 25 September 1896
