The system of transliteration developed by Mr. E. M. Satow, of the British Diplomatic Service, which has been put to practical use by that gentleman in his work entitled "List of Korean Geographical Names," would seem well adapted to meet future needs. It gives a simple series of equivalents for Korean sounds, and is remarkably free from diacritical marks. Mr. Satow's system has recently been employed by English and German authors, while efforts to extend its application would seem to have met thus far with no opposition. The French system of transliteration, which antedates the one above referred to, was developed by the French Roman Catholic Missionaries in Korea, and has been employed by them in their admirable works the "Grammaire Coréenne" and the "Dictionnaire Coréen," by far the most important yet prepared upon the language, and the first given to the outer world. The missionaries aimed at reproducing native speech, and to this end faithfully copied symbols representing shades of sound that are not to be appreciated by the foreign ear, and which in fact are often neglected in conversation by the Koreans of the present day--for the Ön-mun, or native alphabet, has long since lost its purely phonetic character. The simplicity of the French system is marred, therefore, by the use of a multiplicity of letters, which, appearing in the form of aggregations of consonants or of vowels, are more apt to mislead than to guide. Inasmuch as the proper names upon native maps, which are invariably written in the Chinese, may be correctly rendered into English, whereas attempts at the systematic transliteration of Chinese characters have generally failed, it may be well to allude to the points of difference in the two cases. The possibility of the transliteration of Korean depends upon the following: (1) that the Korean pronunciation of Chinese characters is independent of the pitch of the voice or _tone_; (2) that the native alphabet is especially constructed with a view to the easy reproduction of the Korean pronunciation of the same; (3) that the Korean pronunciation of these characters is quite uniform throughout the whole extent of the country; (4) that the Korean equivalents may be readily transliterated into English. All that is necessary, therefore, in fixing a geographic name is to have it written correctly in Chinese and in the Ön-mun. From the latter the English equivalent may be readily obtained. The need of the Chinese form arises from the fact that but few of the natives spell correctly, while many of them write Chinese well; so that it becomes necessary to refer both writings to some authority, by whom the native spelling may be verified.
