Mr. Oswald then communicated the following remarks byMr.Mack, on the fact of black eggs being laid by a white duck of the ordinary domestic breed :- " The egg (observes Mr. Mack) which is herewith sent was laid by a white duck, one of two belonging to Mr. Dickinson of Mitchani, which stray during the day on the common, but are confined at night. The drake was lost about a month since, and then one of the ducks commenced laying black eggs, the other still continuing to lay white ones,-she laid ten or twelve and then ceased for some days ; she has again commenced laying black eggs. The ducks are fed once a day with barley, at the time the other poultry are fed. "Mr. Dickinson, showing the egg this morning to one of the guards on temporary duty on the Brighton rail at Croydon, he said he had a duck which laid the same colour, or even blacker, and that he had raised (at East Bourne) two broods of ducks from black eggs." Haling Cottage, Croydon, May 24, 1851.
