Pastrami, extra lean ("the finest"), is $26 per pound. But once you consume your 1/3-lb on rye, the only thing you have to show for it is an extra fold over your belt and a spicy aftertaste.
The magnificently illustrated, beautifully organized, and weighty (10 lb) third edition of du Vivier's Atlas of Clinical Dermatology is more than well worth the price of $22 per pound.
The book is divided into 32 chapters consisting of morphology and distribution of skin lesions, normal structure and function, common cutaneous disorders, tumors, infections, tropical infections, drug eruptions, blistering diseases, developmental disorders, vascular lesions, disorders of appendageal structures, psychological disorders, the neonatal period, pregnancy, disorders with regional variations, and skin side effects of corticosteroids.
