" Although it shew not the ag&nt, yet it sheweth a rule and analogy in 

 nature, to say, that the solid parts of animals are endued with attractive 

 powers, ivhereby from contiguous fluids, they draw like to like ; and that 

 glands have peculiar powers attractive of peculiar juices." 



BERKELEY. 



"Even herein consists the essential difference, the contra-distinction, of an 

 organ from a machine ; that not only the characteristic shape is evolved 

 from the invisible central power, but the material mass itself is acquired by 

 assimilation. The germinal power of the plant transmutes the fixed air and 

 the elementary base of water into grass or leaves ; and on these the organijic 

 principle in the ox or the elephant exercises an alchemy still more stupen- 

 dous. As the unseen agency weaves its magic eddies, the foliage becomes 

 indifferently the bone and ite marrow, the pulpy brain, or the solid ivory." 



COLERIDGE.
