TOWING. 



held at the surface of the sea, the collector sitting 

 in a boat rowed gently along. The afternoon and 

 evening of a calm sunny day is most productive, 

 especially in the latter part of summer or autumn, 

 when the lovely Medusce^ the little Beroe^ and many 

 forms of freely swimming Annelida and Crus- 

 tacea occur in abundance. At frequent intervals, 

 the bag of the net must be reversed and plunged 

 into a glass jar of clear water, when the captives 

 will float off into the vessel. 



For many details of this and other modes of 

 collecting, and of the history of the curious crea- 

 tures obtained thereby, I beg once more to refer 

 to my Devonshire Coast," Aquarium," and 

 " Tenby," which are expressly devoted to these 

 subjects.
