PLATES IN VOL. I. 



THE vignette in the title page is an ideal view of mountains 

 and rocks. The eagle, the chief inhabitant of such regions, 

 is introduced to animate the scene. If allegory be wished, it 

 may appear in the dispersion of clouds of obscurity but 

 that the eagle eye of some future Newton will be required, 

 to explain the laws of nature in this difficult province.
