On March 17th began what our Egyptians called the Khamsin, and the Arabs El- Dufun (Bedawin, Dafun) generically; and specifically Dufun el-Surayya (”of the Pleiades””). Sky dark without clouds. At night, yellow clouds over moon. Gusts alternately hot and cold. Highly electrical; few could sleep at night. Tents left open. It was followed by damp and gloomy weather, which the Arabs attribute to the Intikal el-Shams (”vernal equinox”). This began on March 19th, and lasted till the 22nd. Aneroid falls lower than we have yet seen it.
