| Title | Copy letter from an unknown correspondent; to Dr. Harold Jeffreys; Meteorological Office, South Kensington, S.W.7. |
| Date | 24 June 1921 |
| Description | Refers to Dr. [Harold] Jeffreys' paper 'Certain geological effects of the cooling of the earth'.

Suggests that this might be worth while to include and asks if Dr. Jeffreys would like his paper back to do so. |
