136 THE DEPTHS OF THE SEA. [CHAP. in. 



Lewis should then be worked in the like careful manner ; and as 

 the 'cold area' would here be encountered, special attention 

 should be given to the determination of its boundaries, and oi 

 the sources of its climatic peculiarity. These would probably 

 require the extension of the survey for some distance in a N.E. 

 direction, which would carry the vessel into the neighbourhood 

 of the Shetland Isles ; and Lerwick would then be a suitable 

 port for supplies. Whatever time might then remain would be 

 advantageously employed in dredging at such a distance round 

 the Shetlands as would give depths of from 250 to 400 fathoms 

 Mr. Gwyn Jeffreys' dredgings in that locality having been limited 

 to 200 fathoms. 



" The Natural-History work of such an Expedition should be 

 prosecuted under the direction of a Chief (who need not, how 

 ever, be the same throughout), aided by two competent Assistants 

 (to be provided by the Eoyal Society), who should be engaged 

 for the whole Cruise. Mr. Gwyn Jeffreys is ready to take charge 

 of it during the first five or six weeks, say, to the end of June, 

 when Professor Wy ville Thomson would be prepared to take his 

 place ; and Dr. Carpenter would be able to join the Expedition 

 early in August, remaining with it to the end. It woulel be a 

 great advantage if the Surgeon appointed to the Ship should 

 have sufficient knowledge of Natural History, and sufficient 

 interest in the inquiry, to participate in the work. 



" The experience of the previous Expedition will furnisli 

 adequate guidance as to the appliances which it would be 

 necessary to ask the Government to provide, in case they accede 

 to the present application. 



"With reference to the Scientific instruments and apparatus 

 to be provided by the Eoyal Society, the Committee recommenc 

 that the detailed consideration of them be referred to a Specia 

 Committee, consisting of gentlemen practically conversant witl 

 the construction and working of such instruments/' 



Eesedved, That the Eeport now read be received and adopted 

 and that application be made to Her Majesty's Goveriimem 

 accordingly.
