The fore part of the lunar eclipse on the 21st was well seen at Tottenham, and 

 it was remarked that the approach of the earth's shadow was preceded by a slight 

 iridescence, forming, as it were, part of a halo on that side the moon : this was evi- 

 dently owing to haze in our own atmosphere. When the earth's sliadow bad 

 proceeded so far as to bisect the moon vertically, the lower half of the disc having 

 passed behind the edge of a dense Cirrosiralus, it presented, for a few minutes, 

 the singular appearance of the luminous circle suddenly reduced to a quadrant.
