A reference to the place of the Michigan Salt group in the 

 Palaeozoic series makes the presence of salt here easily un- 

 derstood. The horizon seems to be salt-bearing in other 

 places in Southern Virginia. There is a salt ooze near Max 

 Meadows, at about this geological horizon. 



The Secretary suggested, in addition, that the underlying 

 Vespertine (Pocono) sandstone is a great salt producing for- 

 mation in the Ohio river up-country. That the gypsum 

 is an acid reaction upon the eroded outcrops of the lime- 

 stone he showed in Proceedings A. P. S. Vol. IX. p. 34, 

 1862. 



Mr. J. F. Mansfield of Cannelton, Beaver county, Pa., 

 communicated by letter, dated House of Representatives, 

 Harrisburg, February 4, 1881, a drawing, life size, of a fine 

 fossil Eurypterus found by him in the shale immediately be- 

 neath the Darlington Cannel Coal bed, Lower Productive 

 Coal measures, with a request to have the specimen studied 

 and described. 



Mr. E. B. Harden exhibited two models in plaster, one 

 geologically colored, the other uncolored, of a large part of 

 Blair county. Pa., on a scale of 8000' : 1" ; vertical scale ex- 

 aggerated 2J times. 



Captain E. Y. McCauley, U. S. N., communicated for pub- 

 lication in the Proceedings an alphabet and syllabary of the 

 Egyptian language, for the use of students, in 32 MS. pages, 

 reducible to 8vo size for the Proceedings. 



The Publication Committee reported in favor of a full ex- 

 change of all publications, so far as sets could be made, with 

 those of the Musee Guimet at Lyons, which was approved 

 and ordered. 



Pending nominations 927 to 933 were read, and the meet- 

 ing was adjourned.
