OBSERVATORY L0O-B00K. 



1883. 



heavy fall of snow was 

 rendered impassable for 



Nov. 9. — Barometer No. 1252 was brought up yesterday, 

 and hung in oak box beside the door of Mr Omond's room 

 to-night. 



Nov. 10.— To-day the first 

 encountered, the road being 

 ascent, and difficult for descent. 



Nov. 12. — Glory seen on fog in north valley at 16 h 

 10 m : radius of ring about 2° by stephanome — red 

 outside. There was also a small inner ring, a mere lump, 

 also with red outside. 



Nov. 13. — Just after sunset blue shadow of earth seen 

 rising in eastern sky. 



Nov. 17. — The floor of the Observatory was to-day 

 ascertained to be 3 feet 3 inches below the Ordnance mark 

 on the summit of the hill. The index point in the cistern 

 of barometer in oak box is therefore 4405^ feet above sea- 

 leveL This result is, however, only approximate, as the 

 mode of measurement, with a sextant and artificial horizon 

 used at a low altitude, did not admit of very great 



accuracy. Barometer No. 1385 having had a bubble of 

 air shaken out of its stem, was to-day hung inside large 

 Observatory window. 



Nov. 20. — Flash of lightning, with thunder not three 

 seconds after, at 10 h 25 m . At 12 h 30 m telegraph 

 instrument was examined, and lightning paper was seen 

 to be scorched slightly. Another flash seen at 18 h 45 m . 

 Telegraph bell rang at same time, but insulation was not 

 in any way injured. A ladder was to-day lashed vertically 

 to the iron cage for thermometer box. It stands about 6 

 feet clear above the cage, and is well stayed up. 



Nov. 23. — House fly seen crawling inside window of 

 living room. 



Nov. 24. — -This morning snow at door was about eleven 

 feet deep — for the first time a " tunnel " had to be bored 

 up to daylight. Small box mounted on ladder at 16 1 '. 



Nov. 25. — After observation at 20 h the box inside iron 

 cage was cleared out, all the instruments being taken in 

 to the house.
