would give the Academy an account of some subjects of interest 

 connected with the expedition. 



Dr. Northrop stated that he had returned from the Bahama 

 Islands during the summer, where he had spent several months 

 studying their geological features, and had made collections of 

 their flora and fauna of considerable interest. In a short time 

 he intended reading a paper before the Academy, giving the re- 

 sults of his studies in this interesting group of islands. Inci- 

 dentally Dr. Northrop remarked that he had lately seen a 

 turkey buzzard at Cornwall-on-the-Hudson, N. Y,, and stated 

 that this bird is rarely, if ever, seen so far North. 



Dr. Bolton, who had lately returned from a trip to the 

 Hawaiian Islands and California, after an absence of nearly seven 

 months, stated that he had been remarkably successful in his 

 search for sonorous sand, and had enjoyed a very pleasant trip, 

 going and coming. He gave a brief description of the places vis- 

 'ited, and excused his brevity on the score of presenting details 

 to the Academy during the coming winter. 



Dr. Newberry said that the summer had been a busy one. 

 Early in the vacation he made a visit to Silver Cliff, Colorado, 

 on his return finishing his Monographs on the Laramie Flora 

 and the Amboy Clays. He had also studied the flora of the 

 coal basin of the Creat Falls of the Missouri. At first no fossils 

 were found ; finally, in a railroad cut in the vicinity, remains of 

 ferns and conifers were discovered; these belong to the Potomac 

 Group of the Lower Cretaceous. 



Dr. Britton said that he had been closely engaged in bo- 

 tanical work, but found leisure to visit Indianapolis, being 

 present at the meeting of the American Association for the Ad- 

 vancement of Science, where he had a very pleasant time.
