Can you explain to me what a "hand" is in terms of measurement and what a "stone" is in terms of weight. I read a lot but authors who use those terms never think to explain it to us barbarian Yanks.
I don't know what a stone is, but a hand is athe length of a man's hand (about 9") that is used to measure a horse from the hoof to the withers. (The bony bump between the neck and the back.)
The "hand" is a universal horse measurement.
