ever, would sift out the carbonate of lime, and the iron remaining 

 behind would in course of time produce a large percentage where 

 it originally existed only as 1 or ^ per cent. 



Prof. Rogers exhibited specimens of the supposed coal-bearing 

 rocks of Maine, in which was an impression closely resembling 

 Cyclopteris Hihernicus, so common in Great Britain. He was of 

 opinion that these rocks of Perry, Me., belong to the sub-car- 

 boniferous series, so extensive in Ireland — they are abundant not 

 only in New Brunswick and Nova Scotia, at the depth of several 

 thousand feet (and containing the famous asphaltic coal) ; but 

 throughout all the Appalachian chain. They are below the pro- 

 ductive coal series, yet in some cases they do contain workable 

 coal seams two, three, or five feet in thickness. 



Prof. Rogers also exhibited a geological survey of Newfound- 

 land, made by Mr. Jukes in 1824, interesting in connection with 

 the specimens of Paradoxides recently found there. Specimens 

 sent to England had been named P. noviapertus, but this must be 

 given up for that of P. Harlani, bestowed upon the same fossil, 

 described many years ago by Dr. Harlan of Philadelphia. 



Dr. Jackson observed that he had traced the rocks of Perry, 

 Me., to rest directly upon Silurian rocks. 



The Treasurer's Report, in regard to discharging the 

 debt of the Society, was read and accepted. 



Dr. Marcus B. Leonard, of East Boston, was elected 

 a Resident Member.
