NRS-22113 | Selected correspondence inward and outward [Sydney Observatory]

This series contains incoming and outgoing correspondence selected by staff at the Sydney Observatory according to the following criteria: "In preparing the correspondence files in these volumes the material rejected has mostly consisted of enquiries for elementary astronomical information or correspondence relating to the arrangements of visits to the observatory. All correspondence which could possibly have any further interest has been retained. What remains is about 1/10th of the original quantity in bulk."
