But if the model Persian dictionary have its difficulties, far harder will be the task with Arabic, which covers incomparably more ground. Here we must begin with Spain and Portugal, Sardinia and the Balearics, Southern Italy and Sicily; and thence pass over to Northern Africa and the two "Soudans," the Eastern extending far South of the Equator and the Western nearly to the Line. In Asia, besides the vast Arabian Peninsula, numbering one million of square miles, we find a host of linguistic outliers, such as Upper Hindostan, the Concan, Malacca, Java and even remote Yun-nan, where al-Islam is the dominant religion, and where Arabic is the language of Holy Writ. My initiation into the mysteries of Arabic began at Oxford under my tutor Dr. W. A. Greenhill, who published a "Treatise on Small-pox and Measles," translated from Rhazes --Abú Bakr al-Rází (London, 1847), and where the famous Arabist, Don Pascual de Gayangos, kindly taught me to write Arabic leftwards. During eight years of service in Western India and in Moslem Sind, while studying Persian and a variety of vernaculars it was necessary to keep up and extend a practical acquaintance with the language which supplies all the religious and most of the metaphysical phraseology; and during my last year at Sindian Karáchí (1849), I imported a Shaykh from Maskat. Then work began in downright earnest. Besides Erpenius' (D'Erp) "Grammatica Arabica," Richardson, De Sacy and Forbes, I read at least a dozen Perso-Arabic works (mostly of pamphlet form) on "Serf Wa Nahw"--Accidence and Syntax--and learned by heart one-fourth of the Koran. A succession of journeys and long visits at various times to Egypt, a Pilgrimage to the Moslem Holy Land and an exploration of the Arabic-speaking Somáli-shores and Harar-Gay in the Galla country of Southern Abyssinia, added largely to my practice. At Aden, where I passed the official examination, Captain (now Sir. R. Lambert) Playfair and the late Rev. G. Percy Badger, to whom my papers were submitted, were pleased to report favourably of my proficiency. During some years of service and discovery in Western Africa and the Brazil my studies were necessarily confined to the "Thousand Nights and a Night"; and when a language is not wanted for use my habit is to forget as much of it as possible, thus clearing the brain for assimilating fresh matter. At the Consulate of Damascus, however, in West Arabian Midian and in Maroccan Tangier the loss was readily recovered. In fact, of this and sundry other subjects it may be said without immodesty that I have forgotten as much as many Arabists have learned. But I repeat my confession that I do not know Arabic and I have still to meet the man who does know Arabic.
