young lady, that it was not through economy that Nature did not color
deep down in the flower bells, but because "she had not light enough
there to see to paint with." This may be true; but it is certainly not
for want of light that, when she is laying the dark spots on a foxglove,
she will not use any more purple than she has got already on the bell,
but takes out the color all round the spot, and concentrates it in the
middle.
