As it is almost needless 
to state, these altitudes have very uncertain value, 
either because obtained by isolated observations made at different hours, or else 
because to very slightly different levels correspond considerable horizontal 
distances, as between Entebbe and Fort Portal (about 225 kilometres = nearly 
140 miles). 
But for this last inconvenience, greater probabilities of accuracy would 
be presented by the determination of the altitude of Fort Portal. Here there 
is an observatory which has been recently founded, but the height of which 
relatively to Entebbe has not yet been determined geodetically, but was 
obtained from the observed data during the whole quarter, May, June, and 
July, 1906, so that the influence of the various sources of error may be 
regarded as considerably lessened. 
In the subjoined Table III are recorded all these data, the outcome of 
which was that the difference of altitude between Entebbe and Fort Portalf 
is 355 metres (1,170 feet). 
* The calculation has been omitted for Katende which, as shown by the pressure, stands 
at very nearly the same level as Entebbe. 
t From the comparisons made on the 30th and 31st May, and again on the 21st and 
24th July between the two Fortin barometers of the expedition and the barometer No. 2,025 
(Negretti and Zambra) of the English Observatory at Fort Portal, it appeared that the 
former gave a mean indication of 517 mm. =4 inch (at 0°) above that of the latter. Since 
this difference was verified in an equal degree with the two barometers of the expedition, 
which kept in perfect agreement with each other at Fort Portal, as they had before the 
journey, it was thought reasonable to apply to all the pressures yielded by the barometer of 
the Fort Portal Observatory, the constant correction 5'17 mm. To the end of November, 
1907, the correction of the Kew Observatory had not yet been obtained for the Fort Portal 
barometer.
