Zahor died of small-pox here, after collecting much ivory at Fipa and Urungu.

It is all taken up by Lewale.[18] The rains seem nearly over, and are succeeded by very cold easterly winds; these cause fever by checking the perspiration, and are well known as eminently febrile.

The Arabs put the cause of the fever to the rains drying up.

In my experience it is most unhealthy during the rains if one gets wet; the chill is brought on, the bowels cease to act, and fever sets in.

Now it is the cold wind that operates, and possibly this is intensified by the malaria of the drying-up surface.
