to preserve with all possible care, by putting the tender animals into spirit, and 
preserving the larger ones dry, such as the skins of animals, insects, shells, 
fishes, and other bulky articles, which, when well dried, he is to pack in casks or 
boxes, so as to secure them against the attack of ants or other insects, with the 
greatest care. In framing such chests or boxes, as well for his collection, as for 
those of the comparative anatomist, the carpenters of the Congo will be re- 
quired to give all possible assistance. 
Of the number of specimens of each kind to be eel it has been thought 
necessary to limit hin generally to three, lest the stock should occupy more 
room than could with propriety be allowed in the vessel. If however, it should 
be found, on approaching the utmost limit of the voyage, or on the return, 
that sufficient room still remains, he, as well as the others, may all be permitted 
to extend the number of their specimens beyond that prescribed by their in- 
structions. 
The proper times of his going on shore for the purpose of collecting, will 
of course be regulated by your orders, and be such as not to interfere with the 
general convenience of the expedition. 
But whenever you shall have occasion to stop for the purpose of cutting fuel, 
purchasing provisions, or holding communications with the natives, or from any 
other cause, you will afford the several gentlemen in the scientific department 
the means of going on shore, where it can be done with safety, to give them the 
‘ pportunity of enriching their collections; and in general, whenever any thing 
occurs to make a landing on any particular spot very derirable, you will, of 
course, pay attention to any representation that may be made to you for that 
purpose, by any of the above-mentioned gentlemen. 
And as they are required by their instructions to keep, each of them, a regular 
journal, in which every thing remarkable relating to the natural history of the 
objects on which they are respectively engaged is to be entered, it is particularly 
desirable that they should be able to mark down with precision that spot on 
which any thing remarkable may be found ; you will therefore supply them, on 
their application to you, with the latitude and Jongitude of the place where any 
such rare object may have been discovered. 
And as all of them have been given to understand that their journals are, in 
the first place, to be transmitted to the Admiralty, you are to call upon them, 
whenever an opportunity may occur, to send, along with your own, a copy 
or an abstract of these journals, according as you may deem the occasion that 
offers for a conveyance to bea safe or a doubtful one: and to prevent as far as 
possible, your and their labours from being lost to the world, it is strongly
