OF THE SENSES, 



ORGANA SENSORIA. 



" We observe in the eye many exquisite refinements of construction, by 

 which various defects, unavoidable in all optical instruments of human work- 

 manship, are remedied. Of this nature are those which render the organ 

 achromatic, which correct the spherical aberration, and which provide for the 

 adjustment of its refracting powers to the different distances of the objects 

 viewed ; not to speak of all the external apparatus for the protection, the 

 preservation, and the movements of the eyeball, and for contributing in every 

 way to the proper performance of its office. Are not all these irrefragable 

 proofs of the continuity of the same design ; and are they not calculated still 

 farther to exalt our ideas of the Divine Intelligence, of the elaborate perfec- 

 tion impressed upon His works, and of the comprehensive views of His 

 providence ?" RoaET. Bridgewater Treatise, vol. i. p. 32.
