1. The Trias and Permian Formations. — Beneath the 

 Lias there is a series of strata, many hundred yards in total 

 thickness, which was formerly known in geology as the 

 Saliferous, or New Red Sandstone Formation, and divided 

 into two groups, namely the Upper, and Lower.* But 

 recent investigations having shown, that of the fossils found 

 in the lowermost group, not a single species is known in 

 the upper series, nor in any newer strata, this system is now
