Science for Students of Leather Technology (Pergamon, 1966). 24 Furskin Processing The pigment is insoluble in most solvents and is resistant even to concentrated acids, but can be dissolved in alkalis. In colour the pigment may appear as brown, black, reddish-brown, yellow or red. Two types of melanin have been identified, the black, dark brown and grey, exemplified by the skunk, Persian lamb and Siberian squirrel, and known as eu-melanin and the yellow, reddish-brown and red pigment known as phaeomelanin (Greek phaeos, dusky), which occurs in the kolinsky, Japanese weasel and red fox.
The king fox is one of the smallest of the foxes and is about 16 in. in length. It has a soft silky fur and large bushy tail. It is dark blue-grey in colour with silvery guard hairs in mid-winter and changes to a yellower tone later in the season. Furskin Types 51 It lives at 6000 to 7000 ft in Nepal and in the Himalayas, and a similar type is found in Iran. This fox has not been satisfactorily identified. Bacharach in his Furs calls it Vulpes montanus, and d'Hoedt in Animaux äfourrure gives it a similar name as Canis vulpes montanus.
The Spring change of coat may be very drastic in long-haired furskins, since the old shed hair may become felted forming loose balls of fur, and sometimes bare skin patches. The Spring change is complete in mid-summer and while the summer coat may be regarded as fully grown, it has little or no value because of its short hair and poorly developed underfur. Autumn growth is much slower than Spring change and is difficult to observe. It is usually complete in the late Autumn 36 Furskin Processing for foxes, the beginning of Winter for most mammals and late Winter for musquash and other aquatic animals.
