View of a village in the Schwartzwald, or Black Forest. The Black Forest stands in the elbow formed by the Rhine river in its course from Schaffhausen to Basle, and from Basle to Mannheim. It is bounded by the plain that borders the river The Neckar River bounds it on the north, while on the east it is limited by the upper part of the same river, and by an imaginary line drawn from the source of the Neckar to Schaffhausen. The Black Forest owes its gloomy name to the dark aspect of its peaks and slopes which is shadowed by pine-trees. On the brightest day the forest's trees still retain their shadow.

"The Gallirex chlorochlyamys, Green-mantled Turaco, has a general coloration of metallic blue and green or greyish-brown, usually varied with crimson, ...all have erectile crests of different sizes. The bill is red, yellowish, or black, the feet are black. The sexes are alike, the younger are duller. The red feathers yield a peculiar pigment, containing copper, called Turacin, which is reducible to a powder; this is so soluble that the colour is washed away during the rain or in a bath, though regained subsequently."
