The above heights will he found to differ considerably 
from those given by Mr. Baker in his letter, written from 
Khartoum in May, 1865, and published in the Times newspaper 
in June. This arises from Mr. Baker having corrected his 
observations, whilst in the interior of Africa, from what have 
since proved erroneous data: the above are the correct com¬ 
putations of the same observations.
