JELLY FISHES. 63 



have been of little more real use than an equal load of sea- 

 water. Assuming that so much as one ton weight of Medusae, 

 recently thrown on the beach, had been carted away in one 

 load, it will be found that, according to the experiments of 

 Professor Owen, the entire quantity cf solid material would be 

 only about four pounds of avoirdupois weight, an amount of 

 solid material which, if compressed, the farmer might, with 

 ease, have carried home in one of his coat pockets." 



Let me, in closing this very inadequate glimpse of a most 

 interesting group, add that many of these creatures contribute 

 to that phosphorescent appearance of the sea, which is such a 

 wonder and a revelation to those who behold it for the first 

 time. The limits set for the entire volume will not permit me 

 to deal with all the British species ; but I trust sufficient has 

 been said to awaken real interest in these despised Stingers, 

 Jellies, and Sea-blubbers.
