Meteorological Observations. 239 



Between four and five o'clock a.m., a faint image of the sun was 

 perceived on the perpendicular side of a mass of clouds, called in 

 Howard's nomenclature cumulo-stratus. These clouds were lying to 

 the east of the observer. As the sun approached the horizon this 

 image grew more distinct, and when the sun's altitude was about 1 5° 

 it reached its maximum of intensity. At this time rays of light were 

 reflected from the anthelion on surrounding objects. Its apparent 

 diameter seemed to be the same as that of the sun. At one period 

 of its existence it was surrounded by a faint fringe of prismatic co- 

 lours. The orange and red were more distinct than any of the other 

 colours. The gray colour of the cloud rendered it impossible to trace 

 the bluish tints of the fringe with any certainty. As the sun's alti- 

 tude became less than 15° the anthelion became less distinct, and 

 soon afterwards entirely vanished.
