A stroke of the sun, received near the cataract of Ariman in Upper Nubia, and followed by ten days' delirium, soon convinced the younger Werne that his friends' anxiety on his behalf was not groundless. During the whole of their twelvemonth's stay at Chartum, they were mercilessly persecuted by intermittent fever, there most malignant, and under whose torturing and lowering attacks their sole consolation was that, as they never chanced both to be ill together, they were able alternately to nurse each other. At last, fearing that body or mind would succumb to these reiterated fever-fits, and the first expedition up the White Nile having, to their great disgust and disappointment, sailed without them, they made up their minds to quit for ever the pestiferous Chartum and the burning steppes of Bellad-Sudan. Whilst preparing for departure, they received a visit from the chief Cadi, who told them, over a glass of cardinal--administered by Dr Werne as medicine, to evade his Mahomedan scruples--that Effendina (Excellency) Achmet Bascha was well pleased with the brotherly love they manifested, taking care of each other in sickness, and that they would do well to pay their respects occasionally at the Divan. This communication was almost immediately followed by the arrival at Chartum of Dr Gand, physician to Abbas Bascha. This gentleman had been a comrade of Ferdinand Werne's in Greece, and he recommended the two brothers to Achmet, with whom he was intimate, in true Oriental style, as men of universal genius and perfect integrity, to whom he might intrust both his body and his soul. The consequence of this liberal encomium was, that Achmet fixed his eyes upon them to accompany him, in the capacity of confidential advisers, upon a projected campaign. Informed of this plan and of the advantages it included, the Wernes joyfully abandoned their proposed departure. Joseph was to be made house-physician to Achmet and his harem, as well as medical inspector of the whole province, in place of Soliman Effendi, (the renegade Baron di Pasquali of Palermo,) a notorious poisoner, in whose hands the Bascha did not consider himself safe. Ferdinand Werne, who had held the rank of captain in Greece, was made _bimbaschi_ or major, and was attached, as engineer, to Achmet's person, with good pay and many privileges. "At a later period he would have made me bey, if I--not on his account, for he was an enlightened Circassian, but on that of the Turkish jackasses--would have turned Mussulman. I laughed at this, and he said no more about it." Delighted to have secured the services of the two Germans, Achmet ordered it to be reported to his father-in-law, Mehemet Ali, for his approval, and took counsel with his new officers concerning the approaching campaign. Turk-like, he proposed commencing it in the rainy season. Mr Werne opposed this as likely to cost him half his army, the soldiers being exceedingly susceptible to rain, and
