11. Incidental. 



Clarence's dream of wrecks, corpses, wonderful treasures, and 



" reflected gems 

 That -woo'd the slimy hottom of the deep, 

 And mock'd the dead bones that lay scatter'd by," 



has not yet, I believe, been realized by any dredger. I have in 

 this way explored for between 40 and 50 years all our own seas, 

 besides a considerable part of those on the coasts of North America, 

 Greenland, Norway, France, Spain, Portugal, Morocco, and Italy, 

 but I have never found any thing of value except to a naturalist, nor 

 any human bone, although many thousands must have perished in 

 those seas. 



12. Concluding Remarks. 



To give a better idea of the ocean and of its life in the depths as 

 well as on the surface, let me strongly recommend my hearers to 

 read Mr. Moseley's admirable volume entitled ' Notes by a Natura- 

 list on the " Challenger." ' His graphic account of this marvellous 

 voyage far surpasses in interest (to say nothing of accuracy) every 

 work of fiction or imagination, and it has not the melancholy dull- 

 ness 'of most books on history and travels. 



The subject of this Lecture is inexhaustible ; and when our know- 

 ledge of it has become more extended, we must continually say with 

 Seneca : " Our predecessors have done much, but have not finished. 

 Much work yet remains, and much will remain ; nor to any one, 

 born after a thousand ages, will be wanting the opportunity of still 

 adding something." Such increase of knowledge must tend to 

 confirm our acknowledgment, with a reverential awe, of that Great 

 Creator whose wonderful works are dimly seen in every form of life, 

 marine and terrestrial, and especially in 



" all that glides 

 Beneath the wave, yea, in the wave itself, 

 And mighty waste of waters."
