SOME PROBLEMS OF THE SEA. 23 



solution of which the Zoologist and the Geologist join 

 hands — and fortunately we have both in this Biological 

 Society. It is a matter, moreover, upon which we are 

 likely soon to have further information, as Mr. Stanley 

 Gardiner has recently returned from his great exploring 

 expedition from Ceylon down to the Seychelles, under the 

 auspices of the Percy- Sladen Trust, and will doubtless in 

 his forthcoming Eeports, to be published by the Linnean 

 Society, throw a flood of welcome light upon the present 

 condition and past history of the bed of the Indian Ocean. 



In this address I have endeavoured to lay before the 

 Society two examples of modern problems of the sea 

 which are, I think, eminently discussable; which will, I 

 am sure, have to be still further discussed in the immediate 

 future ; and which, as they deal with wide general 

 questions of nature, I hoped might prove of interest to all 

 sections of naturalists in this Society.
