Compared with the quantity of sulphates directly determined (411,0) this sum 
shows a difference of 3,9 or 0,9 ”/o. 
The summing up of the results of the analysis in the usual manner gives the

According to the experience of Prof. LÖNNBERG and his companions the use of 
this water for drinking purposes produced diarrhea which, however, subsided after a 
few days. In spite of the quantity of salt it contained, this water quenched the 
thirst perfectly, and when once accustomed to it the members of the expedition 
liked it very well so that when they again, after some time, had the opportunity of 
drinking the quite fresh water of the river Guaso Nyiri the latter seemed flat and 
tasteless. 
The scarcity of water in the thornbush country and its general aridity makes 
it to some extent the equivalent to a desert. When one sees the grey leafless thorn- 
bush during the dry season and the apparently barren ground scorched by the mer- 
ciless rays of the glaring equatorial sun it looks rather unpromising to a biologist. 
It hardly appears as if such a country could offer the necessities of life to any 
animals. As soon as one turns away from the river there is hardly anything green 
to be seen, if not perhaps a fringe of doumpalms at a distance which appears to 
denote a watercourse. But if one hastens there in the hope of finding water one is 
sadly deceived, the river bed contains nothing but hot and dry sand. In spite of 
all these apparently unfavourable conditions, which cannot fail to make an, at first, 
almost saddening impression on the visitor, the thornbush country is not at all so 
bad as it looks. The naturalist will on the contrary very soon find that it is quite 
an interesting country. The bird life is rather rich and the number of species is, as 
can be seen in the report on the birds collected by this expedition, greater than 
could be expected. The numerous spoors seen in the game paths prove that many 
big mammals live here as well. Most apparent are the big three-toed tracks of the 
Rhinoceros, the marks of the broad horse-like hoofs of Grévy's zebra etc. But soon 
more than spoors are seen. The long necks of the Somali Giraffes tower high above 
the thornbush and are thus observed even if rather far away. The coarse bark of
