Appendix B. 
A result quite conformable (the difference is less than half a metre, or 
IS or 19 inches) is reached by assuming for the calculation the means of the 
data of Entebbe and Fort Portal for seven months of the year 1905 (see 
Table IV). 
It was impossible to include the whole year, because no observations were 
made at Fort Portal from May to September, 1905. Hence, the Entebbe 
Observatory being 3,863 English feet, or 1,177 metres above sea-level, it 
follows that Fort Portal stands at about 1,532 metres (5,025 feet) above 
the sea. 
After a stay of two days at Fort Portal, the expedition started on 
1st June from Fort Portal for Ruwenzori. 
In the appended Table V are given the data of the observations made at 
the various encampments, as in Table VI the corresponding data of Fort Portal, 
where, at the request of H.R.H., Mr. John de Souza, Director of the Observa¬ 
tory, besides the ordinary observations for the hours 7, 14, and 21, made one 
also at noon for the whole time that elapsed between the departure of the 
expedition from, and its return to, Fort Portal. 
From the data of Tables V and VI have been calculated the following 
altitudes:

On 8th June the expedition reached Bujongolo, a place which is comprised 
within the Ruwenzori uplands, and as this formed the basal station and point of 
reference for all the measurements to be subsequently taken during the explora- 
tion, the observations were here made regularly from 16th June to 12th July, 
under conditions far more favourable than those that would be secured while 
en route. The instruments were suspended from a vertical table supported 
by two posts, which were firmly planted in the ground at a height of about 
five feet above the surface, and protected from the effects of insulation and of 
the rain by a large awning extended above at a distance of about a foot. 
At Table VIII are given the results of these observations, which are 
recorded in full, not only because they have been used for the calculation of the
