Western New York; coal-plants from Pennsylvania, and par- 

 ticularly those from the noted locality at Mazon Creek, Illinois ; 

 and) Tertiary plants from the Miocene beds at Florissant, 

 Colorado. 



Next in importance is a fine series illustrating the Miocene 

 fossils of Maryland (Chesapeake formation), selected within 

 the past few weeks by Dr. Martin, ffom the large duplicate 

 collections of the Maryland Academy of Sciences, at Balti- 

 more. Thes^ were placed at his disposal mos!t freely by the 

 President of the Academy, Dr. P. R. Uhler, and every facility 

 was afforded^ for selecting a representative series. 



With these may be mentioned a small but choice collection 

 of Tertiary fossils from France and Belgium, received ni ex- 

 change for American species from M. Jean Miguel, of Herault, 

 France. It is the hope and pui'pose of the Honorary Curator 

 to place in the Museum a full representative exhibit of the 

 Tertiary fossils of the Southern States, with those of Europe 

 for comparison. These sets just mentioned, with some that 

 the Museum already has, are the first instalments of this pro- 

 posed exhibit, and much additional material is promised from 

 several other sources. 



A number of characteristic fossils of the Hamilton group 

 of Western New York, have been obtained/ very recently from 

 the Rev. H. H. Thomas, of Columbia, S. C, who has resided 

 long and collected extensively in the former district. These 

 were secured by Dr. Martin partly by gift and, partly by ex- 

 change, and are to be supplemented by more at a later day. 



Another exchange was made, especially for Triassic plants, 

 with the Museum of Wesleyan UniveH'sity at Middletown, 

 Conn. These, though not nuimerous or showy, are of much 

 value, in that the Museum had previously no representatives 



of the Triassic flora. 



A very valuable set of Cretaceous plants was obtained, also 

 by exchange, from the geological museum! of the New York
