Another drawback to the Arab’s happiness is the failure of his constitution: a man who escapes illness for two successive months boasts of the immunity; and, as in Egypt, no one enjoys robust health. The older residents have learned to moderate their appetites. They eat but twice a-day--after sunrise, and at noon--the midday meal concluded, they confine themselves to chewing tobacco or the dried coffee of Karagwah. They avoid strong meats, especially beef and game, which are considered heating and bilious, remaining satisfied with light dishes, omelets and pillaus, harísah, firni, and curded milk, and the less they eat the more likely they are to escape fever. Harisáh, in Kisawahili “boko-boko,” is the roast beef--the _plat de résistance_--of the Eastern and African Arab. It is a kind of pudding made with finely shredded meat, boiled with flour of wheat, rice, or holcus, to the consistence of a thick paste, and eaten with honey or sugar. Firni, an Indian word, is synonymous with the muhallibah of Egypt, a thin jelly of milk-and-water, honey, rice-flour, and spices, which takes the place of our substantial northern rice-pudding. The general health has been improved by the importation from the coast of wheat, and a fine white rice, instead of the red aborigen of the country, of various fruits, plantains, limes, and papaws; and of vegetables, brinjalls, cucumbers, and tomatos, which relieve the indigenous holcus and maize, manioc and sweet-potato, millet and phaseoli, sesamum and ground-nuts. They declare to having derived great benefit from the introduction of onions,--an antifebral, which flourishes better in Central than in Maritime Africa. The onion, so thriving in South Africa, rapidly degenerates upon the island of Zanzibar into a kind of houseleek. In Unyamwezi it is of tolerable size and flavour. It enters into a variety of dishes, the most nauseous being probably the sugared onion-omelet. In consequence of general demand, onions are expensive in the interior; an indigo-dyed shukkah will purchase little more than a pound. When the bulbs fail, the leaves chopped into thin circles and fried in clarified butter with salt, are eaten as a relish with meat. They are also inserted into marak or soups, to disguise the bitter and rancid taste of stale ghee. Onions may be sown at all seasons except during the wet monsoon, when they are liable to decay. The Washenzi have not yet borrowed this excellent and healthy vegetable from the Arabs. Garlic has also been tried in Unyanyembe, but with less success; moreover, it is considered too heating for daily use. As might be expected, however, amongst a floating population with many slaves, foreign fruits and vegetables are sometimes allowed to die out. Thus some enterprising merchant introduced into Unyanyembe the date and the mkungu, bidam, or almond-tree of the coast: the former, watered once every third day, promised to bear fruit, when, in the absence of the
