:o this formation and not to the Eocene, as has been supposed 



Mongthemare,anthophyllumatlanticum,p]agigostomadumosum, 

 nodidacretacea, etc., all of ^vhich will be noticed in a succeeding 

 aumber. A few particles of the green sand are disseminated 

 Sparsely through the matrix. The order of beds associated with 

 he zeuglodon stratum, is as follows : 1, alluvium ; 2, nummulite 

 .eds, 40feet; 3, ferruginous layer, 1 foot; 4, zeuglodon bed, 

 rom5 to 10 feet; 5, lignite; 6, beds of clay with sharks' teeth 

 ndlea^-es of dicotylednous plants; 7, lignite ; 8, beds with abun- 

 ance of oyster shells, 70 feet-this is represented as a hard rock • 

 S green sand and marie, material soft, 10 feet. This section was 

 irnished by Dr. Kock. We had, however, previously been able 

 ) determine the age of the zeuglodon from the fossil in our pos- 

 ;ssion. ^
