the collector a wealth of fossils or minerals, yet it is not without 

 interest of its own ; it enables us to follow in detail the history of 

 the infilling of a great estuary, and it presents us with, perhaps, 

 the closest analogy to the conditions of the formation of our coal- 

 fields. The Norfolk Broads, therefore, are not so much of value 

 as affording an opportunity for the study of one part of the geological 

 record, as in the lessons they teach as to how some parts of that 

 record were written.

The following references may be some assistance to any who wish to follow the 

 subject further. The most valuable contribution to the Robberds-Taylor con- 

 troversy is the following: " On the Geology of East Norfolk; with Remarks upon the 

 Hypothesis of Mr. J. W. Robberds respecting the Former Level of the German 

 Ocean," by R. C. Taylor; published by J. Cochran, London, 1827 8vo. 68pp., 

 14 pis {See also Phil. Ma^., vol. i., 1S27, pp. 277-290, 346-353, and 426-432). The 

 opposite side of the case will be found in the " Geological and Historical Observa- 

 tions on the Eastern Valleys of Norfolk," by J. W Robberds, Jun. 8vo. Norwich, 



1826. The controversy was continued in a " Reply to Mr. R. C. Taylor's Remarks 

 on my Hypothesis on the Former Level of the German Ocean." Phil. Mag., vol. ii., 



1827. PP- 192-206 and pp. 271-285 To this R. C. Taylor replied in two papers : 

 " On the Natural Embankments formed against the German Ocean on the Norfolk 

 and Suffolk coast, and the silting up of some of its Estuaries." Phil. Mag., vol. ii., 

 1827, pp. 295-304; and "On the Geological Features of the Eastern Coast of 

 England, and Concluding Remarks on Mr. Robberds' Hypothesis." Ibid., pp. 327-331.
