. Animal Life and the World of Nature; A magazine of Natural History. TRACES OF ANIMAL HABITS. By Walter Kidd, PAET II. IN the first part of this article the traces referred to were in every instance areas of hair in which the normal direction was reversed or much diverted. In the cases of the Sloth, Anteater, Baboon and Man, which were considered, the traces left indicate the attitudes in which these four species chiefly sit or lie. Many other animals and other parts of the body might be alluded to, such as the bilateral reversed area of hair on the chest of a smooth-coated domestic dog (also found in most carnivores), or that on the ventral surface of the abdomen in the inguinal region, or the curious small reversed patch over the tuberosities of the ischium, the two former being produced by the favourite attitude of lying, and the last by the attitude of sitting in which the dog so frequently indulges. But enough has been brought forward by way of illustration of this subject, which has been more fully dealt with elsewhere. We have now to consider a different class of change in the direction of an animal's hair connected with muscular activity—with the active rather than the passive habits of animals. These changes take the form : First, of a simple whorl or radiating arrangement of hair; second, of a whorl from which a feather-shaped expansion proceeds against the direction of the adjoining streams of hair and loses itself in them; third, a whorl and feathering terminated abruptly by a transverse ridge or crest standing up like a barrier against the further progress of the feathering. These three varieties of hair-slope may be seen extremely well on most domestic horses. Whorls, featherings and crests may be spoken of as one phenomenon, for every simple whorl is in process of change into a whorl with a feathering, and this into a whorl, feathering and crest. They are obviously related very closely with the muscular development in general, and the l
