Dr. C. T. Jackson exhibited a series of fossil shells and 

 corals from the lead mines of Gratiot's Grove, Wisconsin, 

 which were collected by Mr. Joshua Childs, formerly captain 

 of mines in that district. 



The fossils were all internal moulds, not a trace of any of the 

 substance of the shells remaining. They all belong to the Silu- 

 rian limestone group. A perfect dodecahedral crystal of Galena 

 was also exhibited, which came from the Wisconsin lead region. 



Joseph G. Norwood, M. D., of Madison, and John T. 

 Plummer, of Richmond, Wayne county, Indiana, were 

 elected Corresponding Members. 



J. M. Whiton and Henry Warren, Esq's., were elected 

 members of the Society.
