that the presence of Nerztina in the raised beach at Hora did not 
necessarily imply absolutely fresh water (though the identification 
of Neritina danubialis was confirmed by Vicomte d’Archiace on 
a specimen from the same place)’; but he submitted that this was 
not necessary to his argument, which was that the presence of 
these shells did show that at the time of this deposit there was no 
influx, as there was at present, of Mediterranean salt-water to the 
locality. The only way, as it appeared to him, by which it could be 
kept out, would be by a difference of level between the Mediter- 
ranean and the Sea of Marmora, the latter being the higher. If 
this were granted, the Author saw no reason to prevent the fresh 
or brackish water from having stood at one period at the level 
indicated by this beach, or at any other level required to effect the 
erosion of the Dardanelles Channel.
