O. H. F. Peters—Discovery of two New Asteroids. 49 
The loss of the gaseous contents by the action of solar heat 
readily explains the loss of the tail and diminution of bright- 
ness observed in the case of several comets in their successive 
revolutions, and their final disappearance from sight will follow 
as an inevitable consequence, the number of revolutions neces- 
sary rive them of their gaseous contents depending 
principally upon their size and the nearness of their approach 
to the sun at their perihelia. 
The combustion of the hydrogen and carbonic oxide con- 
tained in meteorites, when liberated by the heat caused by their 
entrance into the atmosph ere, must contribute greatly to increase 
the intensity of the heat, and both in this way, and by the con- 
sequent sudden expansion of the imprisoned gases, may hay 
much to do with the bursting of the masses, and the violent ie 
tonations which attend their appearance.
