Observatory 10th Dec 1889 Frank Jones Esqre Dear Sir Many thanks for your note about the meteor. On the enclosed map I have marked down the directions in which different observers saw the meteor, and you will see that ??, Grafton, Armidale, Tenterfield, Emmaville??, Bingara and Campo Santo, though quite independent: agree in fixing the point somewhere between Barraba & Narrabri, and if you would kindly mark a line on the map in the direction in which you saw it, I should be very much obliged to you.

Observatory Sydney July 28th 1858 Sir There will be sent to you this day via Grafton (to the care of Mr Shoveller) a maximum shade thermometer requiring no erection. Allow me to suggest that the striking of the Index in the minimum thermometer may perhaps be prevented by inclining the Instrument a little, so that the descent of the Index may be assisted by its own weight.
