This specialized monograph forms the first compilatory work on keratinizat- 

 ion as a biological phenomenon. 



The keratinized tissues form the hardened outer layers of the vertebrate 

 integument and include skin, hair, feathers, claws, hoofs, etc. 



The macromolecular structure of keratin revealed by recent electron micro- 

 scopy and X-ray diffraction work, is given as a base for the understanding 

 of the properties and biological function of these tissues. The topics "the role 

 of cell membranes in tissue formation" (part of chapter I), "differentiation 

 and protein synthesis" (chapter III), and "the growth of epidermal structures" 

 (chapter IV) are of particular interest to our readers. 



The book is richly illustrated with diagrams. X-ray diffraction pictures, and 

 electron micrographs, and contains an extensive list of references, an author 

 and a subject index.
