Humming- Birds. 207 



yet it is precisely this formless cloud on which the 

 glittering body hangs suspended, which contributes 

 most to give the humming-bird its wonderful sprite- 

 like or extra-natural appearance. How strange, 

 then, to find bird-painters persisting in their efforts

 is a delusion and a mockery. 



Coming to the actual colouring the changeful 

 tints that glow with such intensity on the scale- 

 like feathers, it is curious to find that Gould seems 

 to have thought that all difficulties here had been

 peculiar and glittering colour when the light falls 

 upon it from a particular direction. A true repre-

 somewhat sombre colours, except just at the one 

 point which, when the bird is in the position chosen
