Men in this country acknowledge an introduction by extending the right hand in greeting--the whole hand--for it is positively insulting to offer two fingers, as some under-bred snobs will sometimes do, and it is almost as bad to extend the left hand, unless two persons are introduced at the same time, or the right hand is useless or occupied; in any such case apologize for the hand extended. The right hand is the sword hand, and its extension to a friend is emblematic as a proof of peace, and as a safeguard against treachery. In offering the hand to a friend in the house, always remove the glove, and grasp the hand given in return firmly for a moment. In the street, however, the glove may be retained, if it would cause an awkward pause to remove it; but always in such a case apologize for the covered hand. In shaking hands, do not try to wring them off the wrists, nor press them as in a vise, nor pull them as though they were bell handles, nor fling the two together with violence, so as to cause a report. Let the palms grasp each other firmly, but without any display of energy, and shake the hand moderately for a moment, then release it. Mr. Pecksniff was wont to clasp his left hand over his "dear friend's" right hand, resting in his own right. This practice may be very effective, from a scenic point of view, but it is not countenanced by any rule of etiquette. A lady must first recognize a gentleman by bowing before he is at liberty to salute her. She is the sole judge of the propriety of recognizing him at all, and etiquette requires the strictest deference to her desire in this respect. Should she recognize him, he should raise his hat a little from his head, with the hand furthest from her, and return her salutation with a slight inclination of the body. He may not obtrude himself upon her notice even if he thinks she has not observed him. A lady should never stop in the street to salute a gentleman friend, nor may a gentleman join a lady in the street. Should a lady, however, stop in meeting a gentleman, etiquette requires him to stop also, no matter how great his haste. If he is really unable to stop any time, he must at least pause long enough to state this fact, and apologize for leaving her in such haste. When a lady wishes to end a conversation in the street, she should bow slightly, and the gentleman must at once take his leave. If a lady resumes her walk without any pause in the conversation, a gentleman is then at liberty to join her in her promenade. Married ladies are allowed more freedom in such matters than unmarried ones. It is against all established laws of etiquette for young unmarried ladies to do more than bow to gentlemen in the street, unless the fact of relationship allows some violation of strict etiquette. Unless related, or upon terms of intimate friendship with a gentleman, a lady should never salute excepting by a slightly formal bow. A nod is vulgar, even when exchanged by intimate friends.
