It must be owned that many of the opinions here cited were formed somewhat rashly and without knowledge. Others evidently were the result of careful, intelligent study and comparison, but without sufficient authorities. The information necessary to enable us to form correct general judgments on the Chinese language as an instrument of expression and communication cannot be said even now to be all forthcoming. Nor are we yet in a position to give a final opinion on its rank and value when compared with other languages, or on its descent and kindred. We have among us at present students who are from time to time adding new and interesting facts, which will greatly help the future philosopher to form conclusions wide and general and at the same time accurate. But much still remains to be done before the genius and constitution of the Chinese language are thoroughly understood, and before its rank and value in the world's speech-tribes can be definitely settled. In some of the chapters which follow, an attempt will be made to bring together some of the materials which may be used hereafter in the building up of accurate knowledge and the formation of scientific deductions.
