This splendid MS. on red and blue satin is, in fact, the first that has reached Europe in the language and writing of the Lolos, almost unknown a few months ago; before the important Journey of Exploration in Western Sz'e chuen, by Mr. E. Colborne Baber, now Secretary of the Chinese Legation at Peking, noticed by him in a paper addressed to the Royal Geographical Society of this country. From this paper we learn that Mr. Baber displayed a remarkable diligence in procuring materials for the study of the language and writing of the Lolo population; his paper comprising a vocabulary, copy and tracing of three documents in the Lolo writing; but, till the arrival of this wonderful MS., it must be confessed that we had no other Lolo documents.
