 Troy weight. In mediaeval times nearly ail towns, or 

 seats of commercial activity, had their own standards 

 of weight and measure. In the early part of the four- 

 teenth century the "Pound of Troy" was accepted in Eng- 

 land, and many other places, for weighing bread, silk, 

 gold, silver aad jewelry; it is now used for gold and 

 silver only. One kernel of the wheat of Troyes equals 

 one grain troy.
