Letter from John Herschel, Amla XXXIX, to [Mary Cornwallis Herschel] Herschel is now camped a stone's throw from the railway station, about a mile up the line, with his observatory about three-quarters of a mile away. The heat is becoming more than he wishes to face and he describes the temperature across day and night. Clouds threatened yesteday, but today the instrument is up. His carriages are ordered for the day after tomorrow. He has nothing from Mary later than the 16th, but for the telegram. Her waiting should end three days after she receives this letter. 24 April 1872
