the world may produce. Every precaution has been taken to 
guard against the object of the expedition being disappointed. 
_** The Congo” (the vessel which is to proceed up the river is so 
named) does not draw more than four feet of water. When it 
shall be found impracticable to proceed further in her, the un- 
dertaking will be confided to two smail cutters which are joined 
together, the masts and sails being stacked between them so as 
to leave the nayigators the full range of each, and these will not 
draw more than eighteen inches of water. Such arrangements 
give fair promises of ultimate success; but that which gives us 
most hope is the care taken to man this little expedition in the 
best possible manner, The hands to be employed, in number 
about 50, are all yolunteers. None but those who are proved 
most efficient are accepted. Their exertions are stimulated by 
double pay. The officers are selected for their merit alone, and 
promotion is promised to those who may return. A trial of the 
vessels above mentioned, which are intended to be employed for 
the purposes above described, will shortly take place on the 
Thames. They will leave England early in the present month 
under the command of Captain Tuckey. It is expected it. will 
take from eighteen months to two years to accomplish the ob- 
jects of the voyage. Some natives of that part of Africa have 
volunteered their services, and, it is highly probable, will prove 
of great advantage. One represents himself as born more than 
300 miles up the Congo, at a village on the banks of that river; 
and another as still further up. They speak the native language 
with fluency, as also English, and, it is said, have given some 
valuable information of the several kingdoms through which they 
qwnust pass,

probably recollect that Dr. Balfour of Edinburgh published in 
1514, in the Edinburgh Medical and Surgical Journal, two re-
