 on the top of this haze lay a blanket of fog, as if 

 supported by the haze. Gradually as the day advanced, this 

 canopy of fog cleared away leaving the thick haze with 

 the hill-tops only projecting through it. At 22 h a meteorite 

 was seen travelling from N. of the Zenith N 3 ". Another 

 was seen at 23 h to E.S.E. altitude, probably 60°, fall-

Oct. 31. — Fog on summit at times till 16 h . Clear 

 thereafter, and sky above clearing being cloudless after 

 21 h . Lunar coronas seen in evening. As the Stevenson 

 Thermometer screen in which the thermometers have 

 been exposed during summer has lately got very 

 frequently clogged with snow, the small winter-box 

 was put out to-day after 23 b , 54 inches above the surface 

 of the snow.
