Greene at Washington, D. C, in 1898. Dr. Britton followed 

 with remarks upon the peculiar physiography of the Hempstead 

 plain, its isolation, and the lack of trees, which is perhaps clue to 

 fires. 



The second paper was by Miss Anna Murray Vail on " Some 

 rare Books recently added to the Library of the New York 

 Botanical Garden." This will shortly appear in the Journal of 

 the New York Botanical Garden. Among some 400 works of 

 the older botany recently procured, and now exhibited to the 

 Club, the oldest is a fifteenth century MS. of Macer Floridus De 

 virtutibns hcrbarum, in Gothic letters. The oldest printed volume 

 is one of the Ortus Sanitatis, from the end of the fifteenth cen- 

 tury ; the next, the Venice edition of 1509 of the Aggregator 

 practiens, one of the herbals often known simply as Herbarius. 

 Later notable works secured, include many of those of Mattioli, 

 Dodoens, and Lobel ; the rare first volumes issued by Dodoens 

 (his De frugitm Historia, 1552) and by Clusius (1 557) ; also a 

 copy of Clusius' greatest work, his Rarioriun of 1601, of special 

 interest because a presentation copy from Clusius himself. 

 Rarities include a Passaeus of 1614, and the elephant folio of the 

 Hortus Eystettensis of 1613, in unusually fine preservation. 

 There is a fine copy of Rivinus of 1690; and one of Linnaeus' 

 rarest works, his autobiographical pamphlet of 1741, " Orbis 

 eruditi judicium" believed to exist in only four copies. 



The third paper was by Dr. Rydberg, a " Review of a recent 

 Monograph of Campanula rotundifolia and its Allies." In the 

 discussion of the paper Dr. MacDougal called attention to the 

 work of Goebel on this plant, saying that Goebel had been able 

 to produce rounded leaves on Campanula, by experiment, and in 

 any part other than the inflorescence, but that it had not been 

 possible to prevent the formation of the rounded basal leaves. 



The final paper was given by Dr. Arthur Hollick on " Buried 

 swamp Deposits of Maryland." Along the shores of the Chesa- 

 peake Bay swamp deposits of the Pleistocene era are being un- 

 covered by water action. These occur under from five to thirty 

 feet of gravels. Among the vegetable remains discovered, there 

 were described and shown stumps of the bald cypress, cones of
