Prof. Roofers exhibited a cast taken from the surface 

 of a block of red sandstone, containing the impressions 

 of bones, apparently of an ornithic character. 



The rock was found near the landing at Fort Adams, New- 

 port, along with many others brought there for building purposes. 

 It is stated to have come originally from the quarry in Portland, 

 Conn., and evidently belongs to the Mesozoic sandstone formation 

 of the Connecticut valley. Through the liberal kindness of Capt. 

 George W. Cullum, of the U. S. Top'l Engineers, Prof. Rogers 

 has been allowed to remove the valuable part of the block, which 

 at an early day will be placed in the Cabinet of the Society. 

 The specimen is unique, and it is hoped that, when duly ex- 

 amined, it will help us to a more definite knowledge of some of 

 the animals whose footprints are so abundant in this group of 

 rocks. 



Dr. C. T. Jackson said that all the localities referred to by 

 Prof. Rogers were familiar to him, most of them having been 

 carefully examined by him in his public geological surveys. 



He had at first regarded the red sandstone of Perry, Maine, as 

 New Red or Triassic, but has since been disposed to consider it 

 Devonian. It should be observed that the Devonian series of 

 rocks were not set apart under that name at the time of the geo- 

 logical survey of Maine, but Dr. Jackson had traced the strata 

 of these red sandstones until he found them resting upon rocks 

 now regarded as Upper Silurian, if not Devonian, at Trescott and 

 at Machias. Fossils recentlv discovered seemed to indicate that 

 his first conjecture, that these rocks are Triassic, was well founded. 



As to the age of the red sandstones of Nova Scotia, they were 

 originally described by Dr. Jackson and Mr. F. Alger as New Red, 

 and from comparison of those rocks with those of Connecticut 

 River, Prof. Hitchcock, from mineralogical resemblances alone, 

 first declared the Connecticut River sandstones to be Triassic. 



The Albert coal-mine of New Brunswick was regarded as 

 belonging to the lower Nova Scotia coal-measures, but owing to 

 disconnection of the strata and great disturbance of the rocks, it 

 has been impossible for any geologist to demonstrate their true 

 position stratigraphically. The fossil fishes seem to belong mostly
