THE MOON’S HALO. 
An effect produced by innumerable prism-shaped crystals of ice suspended in the atmosphere and distant forty-five times 
the diameter of the moon’s disc from the ‘outer edge of the moon. The halo, or glory, has prismatic colourings, the red tint at 
the edge nearest the moon and the blue on the outer margin. This distinguishes the phenomenon!from the more usual corona, 
which is]due to aqueous vapour and is coloured blue nearest the Juminary and red towards the exterior rim,
