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 of 
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 Royal 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 Wyville 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 would be a 
sreat 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 furnish 
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 Royal Society, the Committee recommend 
that the detailed consideration of them be referred to a Special 
Committee, consisting of gentlemen practically conversant with 
the construction and working of such instruments.” 
Resolved,—That the Report now read be received and adopted, 
and that application be made to Her Majesty’s Government 
accordingly.
