 English freshwater formations with those of France to be now 

 supplied, and hope that this discovery will stimulate others 

 whose local position affords them opportunity, to persevere in 

 the attempt to collect further traces of the remains of this 

 remarkable class of extinct quadrupeds in the freshwater strata 

 of the Isle of Wight.

 aggregated in a manner analogous to 

 that in which in the crystals of preh- 

 iiite are so frequently met with, Tt^e ■
