The great interest which now attaches to the geography of the Burmese empire and to its relations with the Chinese, seems to call for as much information as can by any means be procured on these subjects from different quarters. In the Chinese library of the East-India Company at Canton is a MS. map, chiefly compiled from the labours of the missionaries; and as its extreme accuracy can be vouched for with respect to those parts of the empire through which Lord Amherst's embassy passed, it is entitled to a degree of credit, which is not hastily to be awarded to Chinese maps in general. An exact copy has been taken from this map of the western part of Yun-nan province. Our latest geographical knowledge of the Burmese country is contained in a map recently published at Calcutta, with the permission of the Bengal government; and as that portion which relates to the Chinese frontier was likely to have been obtained from Burmese sources, it may be worth while to compare it with the Chinese map. As far as relates to the names of places, the Chinese character is the only sure guide within their own territory. Little accuracy can be expected from, or stress laid on, the names written by one set of strangers, the English, and obtained by them through the mouths, or the writing, of another set of strangers, the Burmese. Notwithstanding this difficulty, however, it will perhaps be found that a considerable degree of correspondence exists between the two maps.
