eclipsed portion of the moon by a distant obstacle, such as the pro- 

 iection of a roof or the cornice of a chimney, to see the colour of the 

 eclipsed portion change its tint completely ; instead of a brownish- 

 red; I only saw a bright rose-colour, identical with that which so 

 often tints elevated clouds at the rising or setting of the sun. 

 The peculiar colour which sulUes this beautiful tint when we look 

 at the entire moon in an incomplete eclipse, is therefore an effect ot 

 contrast due to the yellowish tint of the ordinary light of our satelhte. 

 As to total echpses. if the reddish-brown tint persists notwith- 

 standing the want of all contrast, it is because an effective mixture 

 then takes place of the rose-coloured rays with the violet rays, which 

 are more refrangible and more abundant towards the centre ot the 

 shadow. The cause is different, but the effect the s^me.—Comptes
