Besides these, Mr. David Duguid,—not related to "Hafed, Prince of Persia,"—chief engineer of the gunboat Mukhbir (Captain Mohammed Síráj), accompanied us part of the way on temporary leave, and kindly assisted me in observing meteorology and in making collections.

The Egyptian commissioned officers numbered six, viz.:—

Ahmed Kaptán Musallam, commander in the navy, and ranking as Sakulághási (major). He had been first officer in the Sinnár, and he was sent to make astronomical observations; but he proved to be a confirmed invalid.

Of the Arkán-Harb (Staff) were:—

Lieutenant Amir Rushdi, who had accompanied me before.

Lieutenant Yusuf Taufik.

Lieutenant Darwaysh Ukkáb, of the Piyédah or infantry. He was also a great sufferer on a small scale.
