Stated Meeting. 



The President, Dr. J. S. Newberry, in the chair. 



Thirty persons present. 



Mr. James F. Kemp exhibited a collection of fossil plants 

 made by Mr. J. H. Perry, in the vicinity of Worcester, Mass., 

 and remarked on them as follows : 



In the Ame7nca?i Journal of Science for February, 1885, were 

 publislied some notes on a Lepidodendro)i found in the graphitic 

 coal mine near Worcester, by Mr. J. H. Perry, and it was 

 thought that perhaps the long-looked-for fossil of these metamor- 

 phic rocks had l)een found to establish their character. On the 

 table are some specimens, kindly sent by Mr. Perry, consisting 

 of two specimens of Sigillaria. a Lepidodendron, and some in- 

 determinate vegetable remains. There is also a series of chips 

 from the enclosing rocks of the coal mine, and also another 

 series from the neighboring hydromica slate and associated mica 

 schists. The resemblance at iirst sight between the graphitic 

 schists and the hydromica slate or phyllite is very close, and they 

 appear, indeed, to be identical. Stratigraphically, however, they 

 strike at exactly right angles to each other, the graphitic schist (i*) 

 running N. W. and S. E., the phyllite N. E. and S. W., parallel 

 to the general strike of the metamorphic rocks in this vicinity.
