This looks exhausting — flirting signals, from Daniel R. Shafer’s Secrets of Life Unveiled, 1877:

“Handkerchief flirtations”:

Drawing it across the lips: Desiring an acquaintance
Drawing it across the cheek: I love you
Drawing it across the forehead: Look, we are watched
Drawing it through the hands: I hate you
Dropping it: We will be friends
Folding it: I wish to speak with you
Letting it rest on the right cheek: Yes
Letting it rest on the left cheek: No
Letting it remain on the eyes: You are so cruel
Opposite corners in both hands: Do wait for me
Over the shoulder: Follow me
Placing it over the right ear: How you have changed
Putting it in the pocket: No more love at present
Taking it by the centre: You are most too willing
Twisting it in the left hand: I wish to be rid of you
Twisting it in the right hand: I love another
Winding it around the forefinger: I am engaged
Winding it around the third finger: I am married

“Glove flirtations”:

Biting the tips: I wish to be rid of you very soon
Clenching them, rolled up in right hand: No
Drawing half way on left hand: Indifference
Dropping both of them: I love you
Dropping one of them: Yes
Folding up carefully: Get rid of your company
Holding the tips downward: I wish to be acquainted
Holding them loose in the right hand: Be contented
Holding them loose in the left hand: I am satisfied
Left hand with the naked thumb exposed: Do you love me?
Putting them away: I am vexed
Right hand with the naked thumb exposed: Kiss me
Smoothing them out gently: I am displeased
Striking them over the shoulder: Follow me
Tapping the chin: I love another
Tossing them up gently: I am engaged
Turning them inside out: I hate you
Twisting them around the fingers: Be careful, we are watched
Using them as a fan: Introduce me to your company

“Fan flirtations”:

Carrying in right hand: You are too willing
Carrying in right hand in front of face: Follow me
Carrying in left hand: Desirous of an acquaintance
Closing it: I wish to speak with you
Drawing across the forehead: We are watched
Drawing across the cheek: I love you
Drawing across the eyes: I am sorry
Drawing through the hand: I hate you
Dropping: We will be friends
Fanning fast: I am engaged
Fanning slow: I am married
Letting it rest on right cheek: Yes
Letting it rest on left cheek: No
Open and shut: You are cruel
Open wide: Wait for me
Shut: I have changed
Placing it on the right ear: You have changed
Twirling in left hand: I love another
With handle to lips: Kiss me

“Parasol flirtations”:

Carrying it elevated in left hand: Desiring acquaintance
Carrying it elevated in right hand: You are too willing
Carrying it closed in left hand: Meet on the first crossing
Carrying it closed in right hand by the side: Follow me
Carrying it over the right shoulder: You can speak to me
Carrying it over the left shoulder: You are too cruel
Closing up: I wish to speak to you
Dropping it: I love you
End of tips to lips: Do you love me?
Folding it up: Get rid of your company
Letting it rest on the right cheek: Yes
Letting it rest on the left cheek: No
Striking it on the hand: I am very displeased
Swinging it to and fro by the handle on left side: I am engaged
Swinging it to and fro by the handle on the right side: I am married
Tapping the chin gently: I am in love with another
Twirling it around: Be careful; we are watched
Using it as a fan: Introduce me to your company
With handle to lips: Kiss me
