Var. under Domestication
Bartlett has seen several cases of ducks without any web, & most of these had deformed beaks (case of correlation)
This is the origin of the supposed hybrids between ducks & fowls – B. compared their sterna & ascertained that they were true ducks. They were sent to him as the above hybrids.
