This fly invariably kills all domestic animals except goats and donkeys; man and the wild animals escape.

We ourselves were severely bitten on this pass, and so were our donkeys, but neither suffered from any after effects.
Water is scarce in the Mburuma pass, except during the rainy season.

We however halted beside some fine springs in the bed of the now dry rivulet, Podebode, which is continued down to the end of the pass, and yields water at intervals in pools.

Here we remained a couple of days in consequence of the severe illness of Dr.Kirk.

He had several times been attacked by fever; and observed that when we were on the cool heights he was comfortable, but when we happened to descend from a high to a lower altitude, he felt chilly, though the temperature in the latter case was 25 degrees higher than it was above; he had been trying different medicines of reputed efficacy with a view to ascertain whether other combinations might not be superior to the preparation we generally used; in halting by this water he suddenly became blind, and unable to stand from faintness.
