It looks as if it was only the half of a hone but if so I have 

 not been able to find the other piece. 



It is remarkable as being a piece of new red sandstone with 

 Encrinite stems on and in it. It seems to be from the very 

 bottom of the sea with a layer of lime forming, and particles of 

 Encrinites, washed into the sand from which they probably grew, 

 but there are no traces of roots or lily heads of the crinoidae. 



It is rather curious, too, that the line of stratification of the 

 rock is at right angles to the lime base, but this may have been 

 a sun-crack made up by a cementing material. 



There are evidences of the clay outside the Western rampart 

 having been used for making bricks by the broken material 

 lying where the old kilns were placed. 



There is also evidence of red sand having been brought into 

 the camp, probably to dust the soft bricks when placing them 

 to dry, and although this specimen of solidified sand containing 

 the Encrinite stems was some distance away and amidst the 

 debris excavated from beside the Roman Vase, it may be that 

 this piece of stone was thrown out and found its place above or 

 about the said vase at the time of brick making. In this case 

 there can be nothing particular about its association with the 

 Romans, except its peculiarity in being the only specimen of 

 the kind I have seen or heard of, and the fact that there is no 

 specimen in the Museum of the Victoria University of a like 

 character, i.e., of Encrinites in the new red sandstone. 



I suppose fossils in the new red sandstone of this district 

 are extremely rare except on the East side at Heaton Norris 

 where some bivalve casts have been found, specimens of which 

 are to be seen in the Museum. 



Only the tracks of Batrachians are common on the Western 

 shores of the Red Sandstone about Lymm, but no fossils unless 

 the pseudo-morphs of salt crystals can be so termed which have 

 been found in the Ship Canal excavations at Warburton. 



From the white calcareous deposit on the stone it would 

 seem that this was taken from the extreme edge of the lime 

 basin in which it grew and that the drift of the new red sand
