 third, Chalk. The second beds may or may not be wanting, else-

36. We propose to avail ourselves of another Fishery^ 

 Exhibition Excursion in order to make a farther advance 

 upward in our geology and at the same time to add a> 

 possible charm to details, which to some m«y be requisite. 

 This excursion preceded the last in order of time. Geological 

 sequence which we regard of first consequence, calls for thia 

 transposition. Vide Table. The- invitation is to the Executive 

 of the Fisheries Exhibition and Foreign and Colonial Com- 

 missioners from "^A Committee of Norfolk and Norwich 

 gentlemen interested in Inland Fisheries, for a day's excursion 

 on part of the rivers and broads of Norfolk, W. Oldham 

 Chambers, Secretary." According to directions we assemble ajb 

 the Liverpool Street Railway Station at 7 a. m. As on previous 

 excursions we start on the London Clay ; proceeding onward 

 we continue in the same formation until we reach Harwich. 

 This is not the first time that we have gone thus far. In 

 1862 Professor Tennant and I visited Harwich, and then sailed 

 up the harbour and river to Ipswich. A fossil turtle in our 

 museum, dredged from the London Clay of Harwich Harbour^ 

 was then secured. This was one of a number which were 

 offered for sale by a collector. Professor Tennant purchased a 

 larger one. The largest specimens were too ponderous. My 

 specimen is concretionary. They are found in stones which are- 

 dredged for the manufacture of Roman cement. Our c- icretion 

 is perforated by the Mollusc saxt'cava, like many of the stones 

 dredged in our own harbour and coast. This locality is 

 Tv^markable as the habitat of the CortjpTiodon eocenns, our first, 

 fruu-oating mammal of a previous note (29). In the proceedings 

 of the Geologists' Association of London just received, our 

 attention is directed by E. T. Newton to Croydon, on the south 

 side of the London Clay. Our present position is on the north 

 side. In this other locality in the estuarine beds a bone of 

 CorypUodon was also found. In the search for other remains £^
