paper presented, and to discover everything they can touching their lithologie and 

 paleontologic characters. The interesting results which have already attended 

 their explorations of the Saint Peter sandstone give great encouragement that 

 something of interest will be developed by a careful and systematic study of the 

 rocks underlying that horizon. When their paleontologic investigations shall be 

 well advanced it may be that a name of some real paleontologic significance can 

 be attached to these rocks in place of the lithologie one now in such universal use. 

 Certainly the retention for the present of the old name cannot add any confusion 

 to nomenclature. The position taken by Mr. McGee is appreciated, and the name 

 proposed by him in Iowa, Oneota limestone, may yet prove to be the best one to 

 adopt for Minnesota and Wisconsin. 



The paper with its illustrations is published as pages ool-ob<S, with 

 plates 10-12 of tins volume.
