Page 71 - The little Bill like that of a Goose, the Eyes marked, the Head, Neck, Breast, Wings, Tail, and Feet formed, the Feathers every where perfectly shap'd, and blackish coloured ; and the Feet like those of other Waterfowl, to my best remembrance.
Page 71 - Of a kind of Filmy substance, round, and hollow, and creassed, not unlike the "Wind-pipe of a Chicken; spreading out broadest where it is fastened to the Tree, from which it seems to draw and convey the matter which serves for the growth and vegetation of the Shell and the little Bird within it.
