332 MEDUSA-FISHING. 



Between each pair of tentacles and the next pair 

 was set a single visual or auditory capsule, compara-

MEDUSA FISHING. 



A sail for a mile or two along the coast opened up 

 to me a new field of interesting research, and made 

 me acquainted with a tribe of beautiful creatures that 

 I had hitherto known only by report. I had provided 

 myself with a ring-net of fine muslin, a foot wide and 

 two feet deep, afl&xed to a staff six feet in length, for 

 capturing my prey; and a basket containing two or

 specimens and bringing them home. At first I sat in 

 the stern-sheets and held the net at the surface per- 

 pendicularly, with the staff against a thole-pin, as if 

 it had been an oar ; drawing it in for examination after
