SPECIAL ENUMERATION OF THE PLANETS AND THEIE 

 MOONS, AS PARTS OF THE SOLAR SYSTEM. 



IT is, as I have already often remarked, the especial object 

 of a physical description of the world, to bring together all 

 the important and well-established numerical results which 

 have been obtained in the domain either of sidereal or terres- 

 trial phenomena up to the middle of the nineteenth century. 

 All that has form and motion should here be represented as 

 something already created, existing, and definite. The grounds 

 upon which the obtained numerical results are founded ; the 

 cosmological conjectures respecting genetic developement, 

 which during thousands of years have been called into exist- 

 ence by the ever-changing conditions of mechanical and 

 physical knowledge: these do not, in the strictest sense of 

 the word, come within the range of empirical investigation.

THE SUN. 



Whatever relates to the dimensions, or to the present views 

 as to the physical constitution of the central body, has been 

 already given. ( Cosmos, vol. iv. pp. 359-401.) It only remains 

 to add in this place some remarks, according to the most recent 

 observations, upon the red figures and masses of red clouds, 

 which were specially treated of at page 374. The important 

 phenomena which the total eclipse of the Sun of July 28, 1851, 

 presented in Eastern Europe, have still more strengthened 

 the opinion put forward by Arago, in 1842, that the red 

 ru mntain or cloud-like projections upon the edge of the
