months of serene weather enjoyed in a tropical climate. The 

 meteorological processes at work in the gaseous envelopes of 

 the dark body of the Sun, are the causes which produce the 

 phenomena termed Sun-spots and conglobate luminous clouds. 

 It is probable that there, as in the meteorology of our owix 

 planet, the disturbances of very multifarious and complicated 

 character depend upon such general and local causes, that it 

 can only be by means of prolonged observations, charac- 

 terized by completeness, that we can hope to solve even a 

 portion of this still obscure problem.
