"[illegible]" layer. Beneath the [illegible] bedded layer about about 3 feet thick there were action of some free for the creature is considerable though of course thus Beneath this layer the chalked is already somewhat shaly and written out as a partial shale almost horizontally. Then gneiss about 1 foot thick and then appears the regular Rochester shale, or far as general appearance for almost bare of fossils. The first abundant fossil gneiss in the Rochester basin bedded limestone also only 27 feet to appear about 15 feet pure top. This gneiss goes down through thick and has some thin layer of limestone filled with the characteristic byssina. Then follow beneath a mass of heavy bedded fossiliferous dolomitic limestone about 15 feet thick. Out give gradually to common of the species of Omerolnia glyptodonta large, also on. Then a sheet gneiss about 4 feet thick. Scarcely fossils. Then open up thin out heavy bedded sandstone slightly cross bedded and in places divided about 6 feet. Followed by sandy and red and green cross bedded limestone forming itself into alternating shale at these gaps of sandstone. This the regular Medusa series for Orthophycus laevis appears almost in these thin beds of sandstone. Sometimes the sandstone have this gneiss irregular 1 inch, and here of to 1/8 to 1/4 inch. At other times flat shale wedging up to 2 inches cream. In other places
