 conscious perception of these relations, though a 

 human mind is at work in them. In spite of all 

 our " consciousness," the obscure intuitive power 

 at work in these human artistic achievements 

 differs very little from the curious force with 

 which a radiolarian builds up its little house in the 

 deep sea or a caseworm fits on its fine, rhythmic, 

 snail-like coat. In both we have the same pro- 

 found, crystal-like constructive power that brought 

 forth the wings of the butterfly, the feathers of 

 the bird, the bodily frame of all the animals and 

 plants, that harmonises so well with strict mathe- 

 matical forms. In Beethoven and Eaphael it is

It is a great work. How few there are in the 

 whole of the nineteenth century that show the 

 wealth of ideas we find in the first volume alone.* 

 And this is only one volume. We have as yet

 questions are omitted from the abridged cheap edition.
