TRACES OF ANIMAL HABITS. 
By WALTER KIDD, M.D. F.Z.S. 
PART II. 
ie 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 
bemg 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 adjoiming streams of hair and loses itself in 
them; third, a whorl and feathering terminated abruptly by a transverse ridge or crest 
standing up lke 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 feathermg, and this into a whorl, 
feathermg and crest. They are obviously related very closely with the muscular 
development in general, and the locomotive activity in particular, of the animals 
presenting them. As their survival-value is nel they do not come under the influence 
of Natural Selection. They do not even constitute a hinterland of the great empire 
of selection, but live under laws of 
their own. It may be well to add 
also that they have no connection 
with artificial selection, for they occur 
with great frequency in wild as 
well as domesticated animals. These 
varied and rather graceful features 
found adorning the hairy garments 
of so many animals look at first 
sight like the gores, gussets, and 
similar mysteries of female tailoring 
designed to make the garments fit 
the wearer's body more neatly. But 
this simple sartorial view will not 
meet the case. The only view of 
E them which seems tenable is that
