erly to the Potomac River, becoming gradually narrower and 

 thinner to the southward. The formation is of mid-Cretaceous 

 age and marks the transition period from the underlying fresh- 

 water Raritan deposits to those of the overlying marine Mon- 

 mouth formation. The only locality where plant remains have 

 been found is on Raritan Bay near Keyport, where the formation 

 makes a bluff some thirty feet high, fronting on the bay. Mr. 

 Berry enumerated sixty-seven species of plants from this locality, 

 which is commonly known as Cliffwood. The plants occur in 

 the clay and furnish most beautiful, but evanescent specimens. 

 New species were obtained in Arisaema, Carpolithus, Aralia, 

 Quercus, Steradia, Celastrophyllum, Salix, Eucalyptus and Ne- 

 lumbo. These will shortly be published in the Bulletin of the 

 New York Botanical Garden. The flora is very closely related 

 to that of the Raritan formation, and a marked feature is the en- 

 tire absence of ferns, remains of which have not as yet been found, 

 although they form over five per cent, in the underlying Raritan. 

 Remarkable remains are those of Moriconia cyclotoxon D. & E., 

 a widespread and beautiful member of the Cupressineae. The 

 Matawan specimens of this differ in being about twice the size of 

 any forms heretofore discovered. Among the most abundant 

 remains are scales supposedly related to the Araucarian genus 

 Dammara, and twigs and cones of Sequoia. Twigs of Cunning- 

 hamites are also abundant. 



The flora shows a rather striking resemblance to that from the 

 Atane beds of Greenland, the large-leaved Aralia Ravniana Keer 

 from that formation reappearing in considerable numbers. Other 

 points of resemblance are identical species of Sequoia, Sapindus, 

 Laurus, Andromeda, Moriconia, Aralia, Magnolia, Dewalquca, 

 etc. This Matawan flora is the latest known Cretaceous flora 

 of the Atlantic coastal plain, all the overlying formations being 

 marine. The paper was illustrated with drawings, photographs 

 of the plant beds, and specimens. 



Professor Lloyd called the attention of the Club to a simple 

 form of auxanometer, consisting of a vertical lever, carrying the 

 record, moved once an hour and so marking off equal intervals 

 of growth, the movement being accomplished by an arm carried
