692 The American Naturalist. [August, 
The Fur of Animals.’—This volume forms one of a series on 
arts and trades, and the author has treated the subject from that point 
of view. He gives first the structure, form and coloration of the skins 
of those animals useful to man either for clothing or for furniture. 
To this is added a classification based on the uses to which the hides, 
hair, wool or fur is put. Following this technical part is a description 
of the animals mentioned, their haunts, the methods of hunting or 
trapping them, the principal markets and the prices paid for the pelts. 
- Lacroix—Dauliard has added much to the interest and value of 
his book by discussing the parasites that attack the skins, as well as 
those which injure the manufactured materials. The best known are 
‘the Dermestes, the Anthrenus, the Attagenus, the Teignes and the 
Acarians. Various ways of destroying these pests are mentioned, but 
the most effectual, in the author’s judgment, is frequent exposure to 
light and air. 
Eighty-nine well-shown figures illustrate the text ‘and contribute 
much to the attractiveness of the book.
