Barton water-lime beds, near the Albion mills, now in the Redpath 

 Museum, Montreal, figured and described by Sir W. Dawson. 



Many of the Fucoids sent away from Hamilton formerly prob- 

 ably cannot be duplicated now. 



THE CLINTON SERIES. 



Although these beds presented nothing new recently in con- 

 sequence of the non-removal of the shales since the freestone grey 

 band was worked out, some interesting slabs, loosened by weather- 

 ing, fell from the rock cutting off the escarpment in rear of the 

 upper reservoir lately. One, a very large flag from the Iron Band, 

 when split revealed an extraordinary number of impressions of single 

 valves of the blue Littgida, L. Clititoni ( Vanuxem) to L. Obiottga, Cofi- 

 rad. There can be little doubt but they represent an assemblage of 

 dead shells, washed up at a time when the Clintons there were 

 slowly undergoing submergence. The ridged-up wave mark of the 

 shallow sea, plainly to be recognized in the layer, is sutficient 

 evidence in proof, where it can be clearly shown that the succeeding 

 upper green band of the Clintons also, which was deposited above 

 it, displays even more pronounced and better examples of wave and 

 ripple marks. 



The Museum possesses a very fine slab from the grey band, 

 Medina, displaying this characteristic impression, but we ought to 

 have a larger and better Clinton flag also to show our visitors than 

 the small specimen now in our case. 



One may, however, hesitate to place it, even if obtainable, 

 among many of the loose specimens now in our collection, which 

 have been seriously injured by frequent removals from their places. 

 We do not realize, unfortunately, that fossils require as careful 

 handling as the botanist displays in the preservation of his plants. 

 A chip or two knocked from a stone, or a few scratches per- 

 haps added, may appear to be of little consequence in the eyes 

 of men unable to comprehend the importance attached to the preser- 

 vation of the cup-shaped summit of a coral, for instance, or the apex 

 of a shell. Yet such seemingly small matters lead to correct classi- 

 fication. 



The Clinton Iron Band at the upper reservoir here enables us 

 to add Lingula acutirostra (Hall) to the list of HamiUon, Ontario,
