Wo bnve ourselves been an eye witness, and could have sworn that the duck was a living animal. In the space of. ten minmes we saw it drink, eat, dabble in the water,stretch its wings* shake its feathers, and do n number of: things, all in a manner peculiar to that bird. ThisvvsV.f.duck seemed to. live, and move—die illusion was corriplete.And yet it was only a machine, made up of* counterpfoise^, a'cylinder, levers, and stops which were put in motion by means of dir^uiboS. It was the very machine made by Vaucanson, and con-structed by him in 1738, and which was then seen by all Paris. It was for a long time in the hands of IIuni-oulin, who exhibited it in Russia and Austria; jh 1781 wo hear of it at Berlin, in the possession of a counsellor, named Beireis.. After his death the machine was forgotlcn, taken to pieces, and left for thirty years in a garret, where it was much injured. At length it fell-into the hands of n philosophical instrument maker, belonging to Berlin, who made vbin endeavors to put it together again. A skilful mechanicianbelonging to Hamburg, Ceoige Tietsa, fortuately learned these facts and obtained tho remains of the beautiful machine. By means of great care, per-severenee and skill, this ^rietz has succeeded in restoring the duck, and has even added scwie now movements (a if; hut lie lias been obliged to make nearly the whole anew.
