The above heights will be 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
computations of the same observations.
REMARKS ON THE THERMOMETER B. W. USED BY MR. S. W. BAKER IN
DETERMINING HEIGHTS. By Staff-Commander C. George,
Curator of Maps, Royal Geographical Society.
This thermometer was one of the three supplied by the Royal Geographical
Society to Consul Petherick, in 1861, and was made by Mr. Casella.
At Gondokoro, in March, 1862, it was lent to Mr. Baker, who made all his
observations with it, and brought it back safe: it has, therefore, been
in use about 4 and 3/4 years.
On November 9th, 1865, Mr. Baker returned it to the Royal Geographical
Society, and it was immediately taken to Mr. Casella, who tested its
accuracy by trying its boiling-point, in nearly the same manner as Mr.
Baker had made his observations.
