394- THE AQUARIAN NATURALIST.

 No sense but that of touch is required for the success 

 of this singular mode of fishing ; and the delicacy

In order to account for the apparent election made 

 by the Lepades and the Balani, as to the sites inva-

 remarkable circumstance, when aware that in the first
