Text Appearing Before Image:
t on the second Tanganyika expedition an immense amount of notes and material were acquired, filling up the obvious lacunar which had presented themselves in any attempt to study the problem up to 1899. In what follows, I have dealt with the problem afresh, and with all the evidence that is now available. In the first place, I have found it necessary to consider the nature of fresh-water faunas in general, and to discuss the probabilities with respect to the origin of certain constant peculiarities which these faunas are found to present. In the next I have dealt at some length with the physical geography and geology of Central Africa, especially in relation to the fact that all the observations which have been accumulated point persistently to the conclusion that the structure and history of this portion of the continent are not what have hitherto been supposed.

MARUNGU ITAWA Kituta Hu7.-.t A- phjrk-it, n THE TANGANYIKA PROBLEM. 9 features of Equatorial Africa being, as a matter of fact, clearly discernible as subordinate expressions of a still continuing effort on the part of the earth to produce a great mountain chain. So far, indeed, from these regions being remarkable for their stability, it is a fact that the interior of Africa is at the present time only rivalled in instability by certain districts of South America, and in the past by those records of terrestrial disturbances which we have in relation to the Alps and other mountain chains. These matters having been discussed, a review has been made of the nature of the fresh-water fauna which is found in all the great African lakes about which anything is, as yet, definitely known; and in this way it has been shown that throughout Equatorial Africa, as in other great continents, there is a normal fresh-water fauna which has nothing peculiar about it, and is certainly not more distinctive of Africa
