radiation —_ planetary space, has demonstrated that the earth 
continues to cool. This cooling is not sensible at the surface, 
because it is opinchenalt almost completely by the heat en 
gated gradually from within toward the outside ; and which 
and theory are fully competent to explain. The loss of 5 
etalon has no influence but at very great depths; whence it 
results that the crust of the earth continues to increase interior- 
ly by newly formed solid layers. | The formation of primitive 
strata is constantly going on; and will only cease at some very 
remote period, when the operation of cooling has attained its 
limit.” 
_ These observations will enable us to account for seis

mates, found in Siberia, and other northern regions. Per- 
haps it. may. incline us to doubt whether the charming letters 
of M. Bailly Sur PAtlantide, are not something more than a 
philosophical romance.
