The large collection made for the New York Botanical Garden 

 by Mr. R. S. Williams bears similar testimony to these facts ; 

 and the present indications seem to be, that when northern Luzon 

 is fully explored, the most numerous cases of specific identity 

 may be as would be expected with Formosa, but the more inter- 

 esting and instructive cases with the hill district comprising part 

 of southwestern China and northeastern India. 



Bornean relationships are not discussed, owing doubtless to the 

 less advanced state of exploration in Mindoro and Paragua than 

 in Luzon and Mindanao, but these should prove equally interesting.

COASTAL-PLAIN AMBER 



By Edward W. Berry 



Recent discussions of the occurrence of amber in the Cretace- 

 ous deposits of the Atlantic coastal plain seem to have overlooked 

 the fact that amber was well known to some of the earlier geo- 

 logical explorers in this region and is frequently mentioned from 

 a number of different localities. Professor John Finch, an Eng- 

 lishman, who visited southern Maryland as well as parts of the 

 intervening region northward as far as Marthas Vineyard during 

 the first quarter of the last century, seems to have been a keen 

 observer and close thinker. On the eve of his departure for 

 England he read a paper before the Philadelphia Academy which 

 was subsequently published in the American Journal of Science 

 under the title " Geological Essay on the Tertiary Formations in 

 America." * Aside from the distinction of casting discredit on 

 the term " Alluvial " which had been applied to the coastal plain 

 deposits collectively, his essay contains a number of interesting 

 suggestions such as that relating to the extension under Long 

 Island of the equivalents of the Plastic clays of New Jersey. The 

 present Cretaceous deposits are included in his " Plastic Clay and 

 Sand Formation " which he considered of Tertiary age, one of his 

 reasons for this being the presence of amber which he assumed
