The river of Manda, called Matanga, is only a departing and re-entering branch of the Lake, also the Luma and Loela rivers--some thirty yards broad--have each to be examined as springs on the south of the Lake.
_July 29th, 1868._--Not a single case of Derbyshire neck, or of Elephantiasis, was observed anywhere near the Lake, consequently the report we had of its extreme unhealthiness was erroneous: no muddy banks did we see, but in the way to it we had to cross so many sponges, or oozes, that the word _matope_, mud, was quite applicable; and I suspect, if we had come earlier, that we should have experienced great difficulty in getting to the Lake at all.
_30th July, 1868._--We commenced our march back, being eager to get to Chikumbi's in case Mohamad should go thence to Katanga.

We touched at Mapuni's, and then went on to the Molongosi.

Clouds now began to cover the sky to the Mpanda, which has fifteen yards of flood, though the stream itself is only five yards wide, then on to the Mato and Moiegge's stockade, where we heard of Chikumbi's attack on Kombokombo's.

Moiegge had taken the hint, and was finishing a second line of defence around his village: we reached him on the 1st August, 1868, and stopped for Sunday the 2nd: on the 3rd back to the Rofubu, where I was fortunate enough to hire a canoe to take me over.
In examining a tsetse fly very carefully I see that it has a receptacle at the root of the piercer, which is of a black or dark-red colour; and when it is squeezed, a clear fluid is pressed out at its point: the other two parts of the proboscis are its shield, and have no bulb at the base.

The bulb was pronounced at the Royal Society to be only muscle, but it is curious that muscle should be furnished where none is needed, and withheld in the movable parts of the shield where it is decidedly needed.
_5th August, 1868._--Reach Kombokombo, who is very liberal, and pressed us to stay a day with him as well as with others; we complied, and found that Mohamad had gone nowhere.
_7th August, 1868._--We found a party starting from Kizinga for the coast, having our letters with them; it will take five months to reach the sea.
