Title: Need help for different sizes. Post by TOMBELAINE on Jan 10th, 2023 at 10:48am
Hello,
I need help for different sizes in a hand. After discussions I had about chalk slingstones with archeologists, I think it's possible that the size of several slingstones are measured with the hands. This is the hypothesis I want to study. So I need your help to establish "an average hand". All responses are welcome and a big thank you to all. |

I agree with Teg -- modern people and their hands are much larger than than our predecessors. You would do well to explore the studies of ancient humans -- Egyptians, Scythians, Greeks & Romans, Europeans etc. Forensic anthropologists (or whatever they're called) will certainly have studied and recorded findings about body size, including hands. A simple look at sword hilts from 1000 or more years ago tells you that hands were smaller 'back in the day'.

Yes, I agree with you.
But my height is 1 m 68. For me, the lenght D is 5,3 cm and E is 2,5 cm. If my height is 1 m 60, D would be 5,0 cm and E would be 2.4 cm. If my height is 1 m 50, D would be 4,7 cm and E would be 2,2 cm. Yes, some differences exist. But ... For example, 15 Hawaian slingstones in museum of Quimper. This is the museum I want to visit. 7 have a width of 2,4 cm. My question is : is it a coincidence ? |

Always with my example, the median lenght is 5,4 cm. Second coincidence !
Yes, I'm not Hawaian and I didn't live in the XIXth century but I see two coherent coincidences. My goal isn't to prove anything but to convince the archeologists that this hypothesis is interesting. Archeologists are scientist ; this is why an "average hand" is useful. My idea may be stupid but if no one tries, we'll never know. |

Hi, Blondsquirrel.
Thanks for the share. Useful and interesting. In my photo, the 1st number is the lenght, the 2nd number is the width and the 3d number is the ratio width/lenght. The longer the lenght, the lower the ratio. It's normal because the width is almost fixed, about 2.4 cm. My hypothesis : 1) Cut the diameter (1 phalanx on the index finger) in a pebble. 2) Cast off each end to obtain a projectile of about 3 fingers. It's simple, fast and efficient to have identical slingstones. In addition, this method is easy to transmit to young slinger. The photo attached to this post summarizes my idea. |

In 1888, Vigors remarked that the slingstones used in New Caledonia had a diameter of exactly 2,5 cm (Kubikova, 2015).
The length of the middle phalanx of my index finger is 2,5 cm. I just contacted the museum and I hope the visit will be possible. Allow me to insist but the length of the middle phalanx of the index finger of many of you would be of great statistical help. Thanks to all. |

Between 40 and 50 grammes. |

@TOMBELAINE - Do you still want hand measurements? Sorry, I meant to post mine but forgot. I'll definitely do it if this is still something you want to gather.

Yes, Joe Meadmaker.
I'm waiting for an answer from the museum, but it's closed in the winter. The size of the human has varied according to the times. For example, I see on a French website that the size of a Neanderthal man was 1.60 meter. I measure 1.68 m. https://www.hominides.com/dossiers/neandertal-et-sapiens-les-differences/ Therefore, some statistical data would be very useful to me to better understand my subject. Thanks :) |

Here are my hand measurements. The F measurement is hard to see in the picture because the line disappears between two fingers. I measured from the first knuckle of the middle finger to the point where the finger meets the palm. If that's not what you want, just let me know and I'll measure it again.
All measurements are in mm. Left: A - 78 B - 34 C - 87 D - 53 E - 26 F - 52 Right: A - 80 B - 35 C - 89 D - 56 E - 28 F - 55 |

Thanks, Joe.
With your hands, you could have made the first bullet on the top left. If I'm pessimistic, you are the only one who answered. If I'm optimistic, you are the first to answer. :-/ Your answers are important. Right or left hand, inch or millimeter ... like you want. |

Rock density are often between 2 and 3 grams per 1 cm3. So, the weights are relatively close. |

My visit to the museum is scheduled for June 15.

Title: Re: Need help for different sizes. Post by joe_meadmaker on Feb 16th, 2023 at 2:45pm
Cool! Do you know if you'll be able to take pictures?
|
Title: Re: Need help for different sizes. Post by TOMBELAINE on Feb 17th, 2023 at 10:05am
For now, I don't know.
April may, I'll contact the museum to prepare my visit. I still need volunteers for the size of their hands :( but my project is progressing :) |

Very late !
These bullets were made with the method between two rocks. Depending of the gesture, the result may vary a little. In addition, any defects in the pebble may not be corrected. The diameters are not always quite round. But 11 out of 15 bullets respect this value of 1 inch or 2.5 cms. Examples : 2.4/2.5 cms, 2.5/2.5 cms, 2.2/2.5 cms and 2.0/2.7 cms for the most flat. My photos are not very good. |
Title: Re: Need help for different sizes. Post by TOMBELAINE on Apr 9th, 2024 at 10:02am
2 examples of defects :
Photo 1 : pebble defect There is a hollow in the stone near the label. Photo 2 : the bullet at the bottom right Missing tip from shock. It's the most flat, the pebble is straight on half of the bottom. This defect cannot be corrected during the polishing. Diameter : 2.0/2.7 cms. |
Title: Re: Need help for different sizes. Post by TOMBELAINE on Apr 9th, 2024 at 10:14am
My hypothesis is that polishing stops when the diameter of the stone corresponds to the phallanx of the index. I contacted the archeological service of French Polynesia, but they didn't deign to answer. Thanks for them.
