eations of the plants represented. Nos. 8 and 3, are beautiful spe- 

 cies of arborescent ferns. The nervures on the foliage of No. 2, are 

 very strongly impressed. The filaments of the leaves on No. 8,' are 

 united at the base, and" considerably curved. No. 5, is a very' sin- 

 gular fossil, and has several equivocal marks in its form and struc- 

 ture. The outlines of the fragment are similar to the hinder part 

 of a fish ; while its flattened body strengthens the illusion. The 

 specimen is about four inches long, three inches wide and one in 

 thickness, composed of ash colored, marly clay. The surface is 

 covered with depressed spines of the eighth of an inch in diameter 

 none were over an inch in length when I received it, and those were 

 all broken and shortened from their original extent. In the same bed 

 a fragment was seen eighteen inches in length and much thicker 

 than this one, but it broke into small pieces in removing it. It may 

 be the remnant of a large Equisetum— the surface is bituminized. 

 No. 6, is also a species of Fucoides, as near as I can determine; it 

 is from the upper bed. No. 10, represents the seeds of some raon- 

 ocotyledonous plant, which are thickly scattered in patches, amidst 

 \\^e fossil leaves in the shale. The seeds are a little enlarged in the 



No. 11, appears to be " Calamites remotus," and was ta- 

 ken from the upper part of the bed. The columns still retain the 

 siliceous cuticle common to canes. The radius of the four columns, 

 of which the specimen consists, being taken, the outlines of the 

 whole circumference is given in the drawing, ^he oblong tubers 

 on the face of the columns are finely preserved. The original whole, 

 must have been a beautiful stem. The lower part of the shale bed

 impressions of broad, delicate leaves between the seams, from which 

 we may infer that wood did not enter into the composition of this
