Modern Magic: A Practical Treatise on the Art of Conjuring

There is another method, in which the trick is performed with handkerchiefs borrowed from the audience. In this case, two metal eggs, like that above described, are used, the blown egg being dispensed with. The performer commences the trick by borrowing two handkerchiefs, a lady’s handkerchief, and a larger one, preferably of silk. These he places on his table, secretly exchanging the smaller one for a substitute of his own, and retires for a moment to fetch a glass. He takes advantage of his momentary absence to insert the handkerchief of which he has gained possession into one of the hollow eggs, and returns with this egg lying (the opening downwards) on his left palm, the other hand holding the glass, while the second hollow egg is concealed in his left pochette. Coming forward to the audience, he picks up, in passing, the larger handkerchief from the table, and handing the glass, as forming the principal portion of the apparatus, for examination, throws the handkerchief over the hand which holds the egg, showing by its outline beneath the silk that it has not been removed, and meanwhile drawing out with the finger and thumb of the concealed hand the handkerchief hidden therein; which is thus ready to be placed in the glass along with the egg, under cover of the larger handkerchief. The rest of the trick proceeds as already described, save that in this instance, the egg not being attached to the outer handkerchief, it is necessary to clip it with the fingers through the handkerchief when the latter is removed. To do this easily and effectually, it is well, in placing the egg in the glass, to place it with the opening upwards, the edges of the opening giving a readier hold than the unbroken surface of the opposite side.
