Tulchan Bishops, bishops appointed in Scotland by James VI. to draw the Church revenues for his behoof in part, a tulchan being “a calf-skin stuffed into the rude similitude of a calf” to induce the cow to give her milk freely; “so of the bishops, which the Scotch lairds were glad to construct and make the milk come without disturbance.”
