mentioned cases to be again in Beering’s Strait by the 1st August, 
1827, calling in your way thither again at Owhyhee, at which place 
Captain Parry has been directed to give the preference of touching in 
his way homeward, for the purpose of affording you intelligence of him. 
“ If you should find that Captain Parry has passed, or should he 
pass after joining you, and that you have heard nothing of Captain 
Franklin, you are, nevertheless, to proceed to, or remain at (as the case 
may be) Beering’s Strait, in the autumn of 1827, as already directed, 
following in all respects the directions already given for your conduct 
in the autumn of 1826. 
“ In order that you may be put in full possession of that part

the Pacific, you are to be particular in noticing the differences of longi-

you may visit in succession. 
“As we have appointed Mr. Tradescant Lay as naturalist on the 
voyage, and some of your officers are acquainted with certain branches 
of natural history, it is expected that your visits to the numerous 
islands of the Pacific will afford the means of collecting rare and curious 
specimens in the several departments of this branch of science. You 
are to cause it to be understood that two specimens, at least, of each 
article are to be reserved for the public museums ; after which the 
naturalist and officers will be at liberty to collect for themselves. You
