Although it is an established rule of etiquette that persons meeting in society are at liberty to speak without an intro duction when they know each other 1 y sight, Americans are not very likely to do so, however familiar they may be with the rule. While it devolves on the host and hostess to introduce their guest, they cannot, of necessity, introduce more than a part of them ; hence a part of the duty must fall upon the gueste them-. selves. The awkwardness, even -tiw> annoyance of repeatedly meeting met and women with whose faces and nameiv. you are entirely familiar, but to whom you have not been introduced, ia con stantly observable in social circles. The presumption that members of the same calling or of the same set always know each other is entirely unwarranted. Even should they know each other, it can do harm. If there be any doubt in the introducer's, to represent them. It ia easy to say: "I suppose, Mrs. or Miss , you are acquained with Mr ," or "No doubt, Mr. , you have met Mr. ." If the parties have been introduced, the offered courtesy will not be superfluous op embarrassing. If they have not been, the politeness is well timed. The absence or neglect of this attention has a tendency to create a sort of antagonism between persons visually acquainted who have met again and again without recognition. Each is inclined to think : "He knows me very well, but he will not speak, If he feels so, lam aure 4. will not be the one to speak first.* We have known persons of prominence, men particularly, to encounter one another at parties and receptions through a whole season without an introduction. Having many friends in common, and being con stantly thrown together, the mistake ia naturally made that they are acquainted. Another bit of etiquette equally well defined is that a lady, after a gentleman has been introduced to her, should, on another meeting, recognise him first, it being her prerogative to drop the ac quaintauce if she sees fit. This bit of etiquette, however, is apt to be ignored, women indistinctly falling into the habit of waiting for men to take the initiative in recognition, as in everything else.
