Meteorological Observations. 239 



outside. I left off about 12 p.m. ; and from the cloudy weather, I 

 never saw the moon until she was nearly full, then only a few minutes, 

 and again on the 10th January, at 4 a.m.; hut the haze was too 

 thick. I thought I might see them in the shade, hut I could not : 

 I have never seen her since. 



" May I ask the favour of your laying this before the Astrono- 

 mical Society, that we might learn if any of the members have 

 observed this appearance in the moon, or have heard that it was 

 seen by others. I shall be happy to learn if it has been taken notice 

 of by any other observer, and their opinion of it. 



" It appeared to me, from the brightness of the light and the con- 

 trast of colour, to be two active volcanos or two mouths of one in 

 action . 



" If there was no star eclipsed by the moon at or about 7 p.m. 

 that night, the white spot that was more like one of the mountain- 

 tops tipped with light than a star, may have had some connexion 

 with it." — Proc. Roy. Astron. Soc. 1S55, p. 89.
