Difference of longitude — 1 53.27 — 1 53.21

 whereas if computed with constant rates without an assumed jump 

 I would have got - l'"53 s 03 and - l-"53 81. 



Thus the results following from the two computations differ much 

 less than for the other places. 



4. Determinations of latitude in 1904. 

 Buku-Zan. For a determination of the latitude I could observe 

 only on June 15 one star in the south, <? Centauri. Of this star 1 

 obtained 8 pointings distributed equally over the two positions. 

 The results were : 



1 st pair (f = — 4° 46' 4"46

 Chimbete. I only succeeded on June 20 in securing 10 pointings 

 on a Crucis, distributed equally over the two positions, with the 

 following results.

5. Final results. 



I finally accept the following values as the most probable results of 



my determinations of the longitude and the latitude of the four stations 



in the interior. For the longitude of Mayili I take the mean of the 



two determinations and for that of N'Kutu I use only that of 1903.
