from every point around giving the appearance of a luminous 

 circle. An appearance, not unlike this, may sometimes be ob- 

 served round the lights in the streets during damp weather; 

 or, by rubbing the eyes also, a similar appearance may be ob- 

 served, owing to the refraction of the rays of light as they 

 reach the eyes, by the contents of the carunculae Tachrymales 

 and glands of the eye-lids, which, owing to the pressure, are 

 spread over the surface of the cornea. 



In these remote latitudes the stars are said to twinkle with 

 a fiery redness ; but this I did not observe. The cone of red 

 light which is observed to accompany the rising and setting 

 of the sun, in this and other northern countries, is probably 

 owing to the great quantity of vericular vapour with which the 

 lower parts 01 the atmosphere are always loaded in these cli- 

 mates.
