| Title | Copy letter from James Hopwood Jeans, Secretary of the Royal Society; to Sir Joseph [Ernest] Petavel, FRS |
| Date | 6 December 1923 |
| Description | Informs Sir Joseph [Ernest] Petavel that [Henry Reginald Arnulph] Mallock has sent in a research paper '['Summary of the results obtained from experiments made during the years 1918 to 1923 of the effects of temperature on the properties of metals']; alongside it Mallock has written a letter, asking if the Royal Society can procure him samples of pure iron and pure carbon steel for future use, which are not available commercially, and can be made by the National Physical Laboratory for around £20 as opposed to costing Mallock £2,000 to produce himself. Asks Petavel if they would be willing to undertake this work. |
