 haps but one or two artificial faces, as if their 

 owners had been content to use the simplest 

 flakes for arrow-points. 



The Sylvania Sandstone — A Study in Pale- 

 ography: Dr. A. W. Grabau. 

 The speaker described field work carried on 

 in company with Professor Sherzer in south- 

 ern Michigan for the state survey. The spe- 

 cial object of study was the Upper Monroe 

 formation and the Sylvania sandstone. The 

 evidences of the eolian (anemoclastic) origin 

 of this rock were presented. An interesting 

 new fauna of late Siluric age and with De- 

 vonic affinities was found in the higher beds. 

 Evidence of the disconformable relation of 

 the Monroe and the overlying Dundee (Onon- 

 daga) was obtained. 



After discussion of both papers, the mem- 

 bers of the section contributed observations 

 made during the summer. Professor J. F. 

 Kemp stated the general results of study of 

 the petrography of the Adirondack region, 

 and Dr. E. O. Hovey gave an account of ex- 

 cursions of Section E of the American Asso- 

 ciation for the Advancement of Science in 

 the vicinity of the Adirondacks. Professor 0. 

 P. Eerkey reviewed his recent investigations 

 in the Highlands of New York, the difficulty 

 of correlation of the Manhattan schists on the 

 south with the Cambrian sedimentaries on the 

 north, but reported the passage of the latter 

 into crystalline condition eastward toward the 

 Connecticut line.

THE AMERICAN MATHEMATICAL SOCIETY 



The one hundred and thirty-fifth regular 

 meeting of the society was held at Columbia 

 University, on Saturday, October 26, a single 

 morning session sufficing for the usually brief 

 program. The attendance included twenty- 

 eight members. Vice-president P. F. Smith 

 occupied the chair. The council announced

There was presented at the meeting of 

 November 5, 1907, a report on "Eecent Ex- 

 plorations and Excavations in Colorado, Utah 

 and New Mexico," by Edgar L. Hewett, di- 

 rector of American archeology for the Arche- 

 ological Institute of America. The paper was 

 illustrated with lantern slides. Professor 

 Hewett was able, with the aid of volunteer 

 students, to carry on an extensive reconnois- 

 sance of ruins on the San Juan River in 

 Utah and Colorado, and interesting views were
