The late Mr.J. G. Nichols, in "Inventories of the Wardrobe, &c., of Henry Fitzroy, Duke of Richmond" (in the Camden Miscellany, vol. iii.), says(at p. lxxxviii.), "I am not aware that this animal is elsewhere known either in natural or heraldic zoology .... It differs from the heraldic antelope in having horns like those of a ram, and a tail like a dog's." The term yale occurs in the College records.
Yard-measure, or Measuring-yard, is only found in one or two examples. It should be drawn sufficiently elongated so as not to be confused with the billet, since it does not appear to have always the inches marked upon it. In neither of the examples on the Brasses in Cheam Church, Surrey, to ancestors of the YERDE family, are the measures so marked.
Yoke, or Double ox-yoke: this device appears variously represented, and two kinds are given in the margin. The first figure is copied from a MS. c. 1580; the second is later. The device is borne but rarely; one instance, that in the arms of PYBERS, where the yoke is made of bamboo, will be found already noted under Cinnamon, and there are one or two others.
