There is no single， generally accepted system for transposing the spell-<br >ing of Mongolian words from Mongolian or Cyrillic script to the letters<br >of the Roman alphabet. Scholarly works by specialists in Mongolian<br >studies employ a system that is highly accurate but (because it uses<br >special letters and diacritical marks) is generally unintelligible to the<br >untrained reader. Popular works on Mongolia use a great variety of<br >systems， so that， for example， the name Genghis Khan might also be<br >rendered Genghiz， Jenghis， Chinggis， and so on. Many authors replace<br >~Kh" with "H，" so that， for example， the Khangai Region becomes the<br >Hangai Region.<br > In this book， we have tried to adhere to a simple utilitarian principal:<br >Mongolian names are given in the forms in which they are most likely<br >to be encountered in other works--especially reference works--on<br >Mongolia， and which， when pronounced by an ordinary reader of En-<br >glish， will yield a reasonable approximation of the sound of spoken<br >Mongolian. For geographical names， we follow the usage of The Ne~<br >York Times Atlas of the World， except in a few instances where the atlas<br >spelling has been altered to conform to the spelling used elsewhere in<br >this book (for example， Altai and Choibalsan).<br >
