XXXVill INTRODUCTION. 
of the expedition, and to the officers under your orders, in obtaining which, 
however, their Lordships cannot doubt yeu will meet with the willing assistance 
and co-operation of those gentlemen who have been engaged to accompany you, 
for the purpose of scientific research. These are, 
Mr Proressor Smitu, Botanist and Geologist ; 
Mr. Tuvor, Comparative Anatomist ; 
Mr. Crancu, Collector of Objects of Natural History ; 
each of whom has specific instructions for his guidance, of which it may be 
necessary to furnish you with a general outline, in order that you may the bet- 
ter be able to afford such opportunities, and such facilities to all and each of 
them, as may tend to promote the several objects, which their Lordships have in 
view. 
Professor Smith, Botanist and Geologist, is directed by his mstructions to 
collect together as many specimens of plants, growing on the banks of the river, 
as time and opportunities will enable him to do; and these specimens, it can 
hardly be doubted, will be very numerous, as the country has never yet been 
explored by botanists, nor have the parallels of latitude, through which the 
river passes, been yet investigated in any part of the world, with the exception 
of south America, and these only partially explored. And in order to enable 
him to execute his laborious duties, a Gardener, from His Majesty’s Botanical 
Garden at Kew, has been assigned to assist the Professor in drying and pre- 
serving, as well as in collecting specimens, to afford him more time to note 
down the prominent characters of the most remarkable plants, which may fall 
within his reach. 
He is also directed to collect the seeds of all new plants, which may offer them- 
selves for the use of the Royal Gardens at Kew; and the supply of these has 
been limited to two packages of each kind, sewed up, with a view to keep the 
stock intire, without breaking into it on any consideration; so that the whole 
collection may be delivered, so sewed up, to the Director of the Royal Botanical 
Gardens, as soon as possible after the return of the expedition to England. 
The Professor is further directed to preserve the fructifications of the more 
delicate plants in spirits, sewed up in small bags of muslin. It has been thought 
right to apprise you of the nature of these collections, in order that, in the ar- 
rangement and distribution of the stores, provisions, &c., on board the Congo, 
a sufficient space may be alloted for their stowage. 
He will also have occasion to examine into the geology and geognosy of the 
country, through which the river shall be found to pass, and to collect speci- 
mens of such stones and minerals as may occur ; and as he is directed to keep.
