A VISIT TO THE GREAT EXHIBITION. 105 



Ya<iri. Dr. Barth mentions a solitary specimen in Kabbi, vol. v., p. 316 t 

 Farthest from the sea in Zariya, or 300 miles, and in Adamawa, or about 

 350 miles. Barter and I considered the Oil Palm to be Polycecious. 



Uses : Sap forms the sweetest kind of Palm wine. Fruit and kernel 

 eaten. Mesocarp of fruit yields " Palm oil," kernel yields " Palm-nut 

 oil" or "Nut oil." Young leaf-buds eaten occasionally. Leaves, when 

 Raphia is not procurable, used for thatching. Wood employed in 

 building. 



At West Bay, in Prince's Island, we saw either a variety of the Oil 

 Palm, or else another species of Elais. The nuts were larger, the foliage 

 brighter green, and the trunk more robust, but we saw neither flowers 

 nor ripe fruit. 



2. Cocos nucifera, Coco-nut Palm. All along sea-coast, and in deltas 

 of rivers near towns. Extends up the Niger to Idda, where it fruits at 

 120 miles from the sea. I have two young trees at Liikoja, more than 

 150 miles from the nearest salt water. 



Uses : Fruit eaten. Oil said to be made in small quantity in Kwfta, 

 E. from Akkra\ 



This list thus includes 10 species of Palms at present known in 

 Sudan, a number not likely to be much increased.

 The Exhibition is a great popular educator, and there is no man, 

 however exalted his intellect or deficient his knowledge, but must gain 

 some advantage from a contemplation of the mind, and inspection of 

 the matter, which together constitute that marvellous whole. In the 

 labyrinthine courts and avenues of our great Technological Palace, we 

 find the practical evidences of modern civilisation, the entire collection 

 forming, as it were, a barometer of the world's progress in art and 

 industry. The richness and variety of the productions of nature, which 

 are exhibited, in conjunction with the most curious contrivances, and 

 appliances of art, must afford immense pleasure, and satisfaction, to 

 everyone possessed of an appreciation for either the useful or the beau- 

 tiful. There is, indeed, food for every mind, but such as are warped by 

 envy or buried in hypochondria. Every profession is enlightened, and 

 each trade stimulated and encouraged, not to say benefited, by the
