Appendix B. 



A result quite cuiifuruiuble (the difference is less than li;ilf ;i metre, or 

 18 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 3,8G3 P^nglish 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 Kuwenzori. 



In the appended Table V are given the data of the observations made at 

 the various encampments, as in Table YI the corresponding data of Fort Portal, 

 where, at the request of H.R.IL, 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 

 exjjedition from, and its return to. Fort Portal. 



From the data of Tables V and YI have been calculated the following 

 altitudes : 



Altitude of Duwona relatively to Fort Portal about m. 54== 177-0 ft. 



„ Kasongo „ „ „ „ „ „ 136= 446-2 „ 



„ Ibanda „ „ „ „ „ „ 458= 518-3 „ 



,, Eihunga ,, „ „ „ ,, ,, 388 = 1,273-0 ,, 



„ Xakitawa „ „ ,, „ „ „ 1,120 = 3,674-6 ,, 



„ Kichuchu ., ,, „ „ „ „ 1,465 = 5,788-2 „ 



„ Buamba ., ,, ,, „ ,, ,, 1,986 = 6,515-8 „ 



On sih .lune the ex])editi()n reached Ijujongolo, a place which is comprised 

 within tlie Puwenzoii uplaiul.s, and as this formed the l)asal station and point of 

 reference for all the measurements to be suljsequently taken dui'ing the explora- 

 tion, the observations were here made regularly fiom 16th June to 12th July, 

 under conditions far more favoui'ablc than those that would be secured while 

 en route. The instruments were suspended from a vertical ta1)le supported 

 by two posts, which were firndy planted in the ground at a height of about 

 five feet above the surface, and protected from the effects of insulation and of 

 the I'ain by a large awning extended above at a distance of al)0Ut a foot. 



At Table YIII are given the i-esults of these obseivations, which are 

 lecorded in full, not only l)ecause they have been used for the calculation of the
