(Abstract.) 

 The author dissents from the interpretation of tyro pit-sections, 

 one on Aldringham Common, the other near Heuham Park Farm, 

 given by ^^. Searles "Wood in his paper " On the Structure of the 

 Ked Crag." Mr. Fisher admits that the former is at a higher 

 level than the Thorpe Crag-pit, and the latter than the AYangford 

 Crag; but he denies that the loam on Aldiingham Common is 

 Chillesford clay, and is doubtful Trhether even that at Henham 

 Park Farm belongs to that deposit. Granting, however, that the 

 loam in the latter case is really Chillesford clay, the author states 

 that it is probably carried under the "Wangford Crag by a northern 

 dip. Thus he considers that neither of these sections contains 

 indisputable evidence of the superposition of the Chillesford clay to 

 the Fluviomarine Crag. He also expresses a doubt of the crag at 

 Bulchamp being a continuation of the "W^angford bed, and states that 

 it much more resembles the Mya-bed as seen at Yarn PQll. 



P.S. A subsequent examiuation of the neighbourhood of Norwich 

 in April 1867, led the author to admit the identity of the Mya-hedi 

 with the Upper Crag of Mr. Taylor, as seen at Toft Monks and 

 Bramerton; and consequently to abandon such of his published 

 opinions as are inconsistent -with that conclusion.— 0. F.
