The few which have not been noticed occur only at rare intervals, and are of but little importance. One device, representing a bees' nest, with a fox and the motto "Quaerendo," though frequently ascribed to the Elzevirs, is in reality none of theirs, being the mark of Abraham Wolfgang, a Dutch printer of considerable repute.
