| Title | Copy letter from Herbert Rix, to Dr Leo Anton Karl de Ball, Director der von Kuffner Sternwarte, Wien |
| Date | 21 February 1893 |
| Description | Rix hopes before now to have sent a definite answer to Ball's interesting letter of 30th January, but the Society has been hitherto so engaged that the Committee which arranges the exchange of publications has not yet been able to meet. When they do, Ball's letter shall be laid before them and Rix has little doubt an exchange can be effected. |
