In so far as possible the plan of arrangeme&t has been to place together as groups those pages having to do with closely allied products. In each chapter the different products have been discussed somewhat as to history and use of product, processes of manufacture, microbiology involved, and bibliography. There is no intention of treating any of these subjects exhaustively, These subjects are developing so rapidly and the fields are so large that it is out of the question to try to do more than to indicate some of the lines of their development in America. The omission of much important work is recognized. Mechanical steps having little to do with the microbiology involved are only briefly described. It is often necessary, however, to deal with processes- as
