But where is the yolk, was used to be said to persons reserving to themselves the best part of any viands, or other things, of which they had the distribution. A man dreamed he had found an egg. A soothsayer who was consulted to interpret the dream, told him that it portended he should find a treasure, the white of the egg representing silver, the yolk gold. The event corresponding with the prediction, the man took to the seer, some of the pieces of silver; but what, said the seer, is become of the yolk? Which thence became proverbial.
