correlation work northward on Cape Cod and southward in New 

 Jersey. In the introductory chapter is included an account of the 

 previous work of others in the reg-ion, and their conclusions, which is of 

 interest historically and also in showing- the evolution of scientific 

 thought and the changes that have taken place from time to time in 

 the interpretation of facts during- the past one hundred and thirty years. 



Numerous references to Staten Island may be found in the text, and 

 one of the quotations is an abstract from the first number of the Pro- 

 ceedings of the Natural Science Association of Staten Island, issued No- 

 vember lo, 1883, describing: the discovery of fossil leaf impressions on 

 the shore at Tottenville. 



The importance of fossil plants in determining- the g-eolog-ic age of 

 strata and in correlating- them is emphasized throughout and is indeed 

 one of the main objects of the monograph. A table of correlations on 

 page 29 g-ives a condensed epitome of the views of a number of recent 

 authorities and the conclusions of the author. The entire insular flora 

 is regarded as included in the Raritan and Cliffwood formations, with 

 possibly some of the Mattewan, and to be Cenomanian and Senonian 

 in age. 



Two hundred and twenty-two species of fossil plants are described 

 and figured, of which Staten Island is represented by six from Arrochar, 

 five from Princes Bay, one from Richmond Valley, thirty-six from 

 Tottenville, thirty from Kreischerville, and one from Green Ridge. The 

 descriptions and fig-ures of these were based upon the specimens in our 

 museum, and among: these the follovvitig- type specimens may be noted : 

 Myrica Davisii, Myrica Hollicki, Platanus aqiiehongensis ^ Pistacia 

 aq^iehongensis, Acer niinidum, Kalmia Brittoniana, Phyllites poinsetti- 

 oides, Williamsonia Riesii, Carpolithus eiwnymoides, Carpolithus vacci- 

 nioides, and Rhizomorphs. 



It is unfortunate that the text of this work was prepared previous to 

 the recent extensive discoveries at Kreischerville, which have added 

 many more species and have still further demonstrated the scientific 

 value of our local Cretaceous deposits.
