The variety known by the name of the Rouen Duck, is of 
the fame fpecies, only of very large growth ; we have feen 
one that weighed upwards of feven pounds, the plumage 
was nearly like the Mallard, we obferved no other difference, 
than that the ring round the neck was confiderably larger, 
and the beautiful chefnut colour on the neck and breaft was 
mottled with white ; this variety retains a large fhare of its 
wild nature, and often quits its dom^ftic aflbciates for its 
former haunts, where it breeds with the wild ones, and is often 
taken with them in the decoys.
