Appendix B. 



A result quite conformable (the difference is less than half a metre, or 

 18 or 19 inches) is readied by ass\nning 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, l>ecause no oliservations were 

 made at Fort Portal from May to September, 1905. Hence, the Entebbe 

 Oliservatory being 3,863 English feet, or 1,177 metres above sea-level, it 

 follows that Fort Portal stands at alwut 1,532 metres (5,025 feet) altove 

 the sea. 



After a stay of two days at Fort Portal, the expedition started on 

 1st June from Fort Portal for Kuvvenzori. 



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 I'ortal, 

 where, at the recjuest 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 Tallies 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 exjjlora- 

 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 

 &n route. The instruments were suspended fi-om 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 al>ove 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
