P. 318, figs. 6 & 7. [Owing to a mistake which I made in selecting the drawings 

 for reproduction, a pair (Figs. 6 & 7) representing a section south of 

 the KoLLiCKERBACH havc been used to illustrate corresponding views 

 under the Waldhalle. The association of Chalk and Drift is nearly 

 the same in both, but the true Waldhalle sections do not show the 

 Boulder Clay coming in again on the edge of the Chalk-cliff as it 

 descends to the beach.— T. G. B., July 17th, 1809.] 

 P. 473, line 4 from top, for ' approch,' read ' approach.' 

 P. 481, line 17 from top, for ' Lag-na-Linnge,' read ' Lag-na-Luinge.'
