Hockheim the beds are much dislocated, and at Wisbaden fossil 

 bones are found, the teeth accompanying which refer them to 

 animals allied to the Lophiodon iapiroides, and to the Sumatran 

 Tapir. These calcareous deposits are only 200 feet above the 

 level of the Mayne, and they are perforated in many places by 

 basalt, upon which they rest. The basalt finally disappears south- 

 east of Darmstadt, and is succeeded by primitive rocks. There 

 are strong salt-springs at Soden, and various mineral waters near 

 Frankfort and Hadnigstein. 



The Falkenstein mountain, though composed of talc-slate, pro- 

 trudes through the high table land in the form of basalt. To the 

 north of this the older rocks disappear, and the district is occupied 

 by grauwacke. The grauwacke is divided into quartzy grauwacke 

 and grauwacke slate ; the latter is very distinct from micaceous 

 slate, and contains casts of Spiriferiy of the Pleurobranchi of 

 Cuvier, &c. ; the former offers Encrinites, and unknown coral- 

 loids. 



At the meetings of this Society on March 17, Jpril 7, and 

 AprWil^ no business was transacted which requires notice in the 

 Zoological Journal ; except that at the meeting on April 7, R. I. 

 Murchison, Esq. F.R.S., one of the Secretaries, presented a cast 

 of the superior portion of a gigantic Saurian femur, from Sussex.
