When the trough was placed on a box to prevent the moisture entering from below, so much dew was deposited on the outside of the roof that it was soon necessary, for the sake of distinct vision, to wipe the glass.

This would not have been of great consequence, but a short exposure to this dew was so sure to bring on a fresh fever, that I was obliged to give up observations by night altogether.

The inside of the only covering I now had was not much better, but under the blanket one is not so liable to the chill which the dew produces.
It would have afforded me pleasure to have cultivated a more intimate acquaintance with the inhabitants of this part of the country, but the vertigo produced by frequent fevers made it as much as I could do to stick on the ox and crawl along in misery.

In crossing the Lombe, my ox Sinbad, in the indulgence of his propensity to strike out a new path for himself, plunged overhead into a deep hole, and so soused me that I was obliged to move on to dry my clothing, without calling on the Europeans who live on the bank.

This I regretted, for all the Portuguese were very kind, and, like the Boers placed in similar circumstances, feel it a slight to be passed without a word of salutation.
