The Natural History of Selborne

After ewes & lambs are shorn there is great confusion & bleating, neither the dams nor the young being able to distinguish one another as before. This embarassment seems not so much to arise from the loss of the fleece, which may occasion an alteration in their appearance, as from the defect of that notus odor, discriminating each individual personally: which also is confounded by the strong scent of the pitch & tar wherewith they are newly marked; for the brute creation recognize each other more from the smell than the sight; & in matters of Identity & Diversity appeal much more to their noses than to their eyes. Thus dogs smell to persons when they meet, when they want to be informed whether they are stranger or not. After sheep have been washed, there is the same confusion, for the reason given above.
