xxxviii INTRODUCTION. 



of the expedition, and to the officers under your orders, in obtaining which, 

 however, their Lordships cannot doubt you -will meet with the willing assistance 

 and co-operation of those gentlemen who liave been engaged to accompany you. 

 for the purpose of scientific research. These are, 



Mr Peofessoe Smith, Botanist and Geologist ; 



Mr. Tudor, Comparative Anatomist ; 



Mr. Crakch, 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 outhne, in order that you may the bet- 

 ter be able to afford sucli 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 instructions 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 moi-e time to note 

 down the prominent characters of tlie most remarkable plants, which may fall 

 within his reach. 



He is also directed to collect the seeds of all new plants, which may oflper them- 

 selves for the use of the Royal Gardens at Kew; and the supply of tliese has 

 ])een Umited 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 

 deUcate plants in spirits, sewed up in small bags of musUn. It has been thought 

 right to apprise you of the nature of these coUections, 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, tlu-ough which the river shall be found to pass, and to collect speci- 

 raens of such stones and minerals as may occur ; and ais he is diiected to l^eej^
