Extract of a Letter from W. C. Redfield, Esq., on newly dis- 

 covered Ichthyolites in the New Red Sandstone of New Jersey. 

 Communicated by Charles Lyell, Esq., V.P.G.S. 



Mr, Redfield has found two distinct fish-beds in the new red 

 sandstone of New Jersey, both containing ichthyolites of the genus 

 Palceoniscus. In the sandstone between the fish-beds he discovered an 

 Ornithoidicnite, and observed numerous slabs exhibiting impressions 

 of rain-drops and ripple-marks. The rain-marks appear as if the rain 

 had been driven by a strong wind, and the direction of the impres- 

 sions indicated that the wind blew fx'om the west, a quarter from 

 which violent squalls or thundergusts are still prevalent in these 

 latitudes,

 Alexandrina (New South Wales), and noticing some fossils obtain- 

 ed from that district.

" On the Silurian Rocks of the South of Westmoreland and 

 North of Lancashire." By Daniel Sharpe, Esq., F.G.S. 



This communication is in continuation of a paper read by the au- 

 thor on the 2nd of February, 1842*, a second visit to the district 

 having enabled him to correct some errors committed on his first 

 examination, and to extend his observations into Lancashire. 



On both occasions Mr. Sharpe took for his base-line the bed of 

 Coniston limestone described by Professor Sedgwick f, being con- 

 vinced that Mr. Marshall has rightly considered that limestone as the 

 lowest bed of the Silurian system in this district]:, and in all his 

 descriptions he adheres to the ascending order. 



1st. Coniston Limestone. — It is doubtful whether this bed is 

 continuous at its western extremity, or occurs only in detached 

 patches. The two western portions of limestone at Water Blain 

 and Low House are a mile and a quarter south of the bearing of the
