tive edition was designed by the meritorious editor of Chronica Botanica, Dr. Frans Verdoorn. It might be of interest to those especially interested in pharmaco-botany that similar attempts at following up the history of medicinal plants by methodically examining the herbals and books on drugs from antiquity up to the late eighteenth century have been going on for quite a while. As a matter of fact, the herbals themselves refer again and again t o the concepts of earlier authors. A study by Hedwig Schwarz resembling that of Finan in the use of plant illustrations as a means of research (and dealing with Chelidonium majus and Paeonia peregrina Mill.-Paeonia ojicinalis L.) was published i n 1931 by the Gesellschaft fur Geschichte der Pharmazie. From 1930 to 1937 there were presented at the University of Base1 a number of Doctor’s theses as contributions t o the history of official drugs (“Beitrgage zur Geschichte der Ofizinellen Drogen”), prepared under the guidance of Professor Heinrich Zomig (and partly with the advice of Professor J. A. H a g e r ) , which had the examination of the herbals and books on herbs through the ages as their basis.

Essential information not readily available elsewhere on manufacturing processes; process machinery; the equipment used for the transportation of fresh and frozen fishery products; methods of rapid freezing ; and important technological developments in feed for animals extracted from seaweed, moss, and alginates are presented. Since publication of the original edition 27 years ago, progress in the technology of marine products has been so rapid that the new edition was entirely rewritten and expanded. It presents considerations of the world’s agar industry; the first attempted statistical survey of the world’s fisheries and shellfisheries and their many products; and serves as a source of information on the technology of fish glue manufacture. It presents what appears t o be an excellent outline of useful information on oceanography, chemical technology, marine botany and biology, conchology, ichthyology, the marine fisheries, fishery technology, statistics, nutrition, fishery by-products, shell-fisheries, whaling, sealing, sponge fishing, and gemology. The book is documented with references to many specialized treatises on the several subjects covered. Its usefulness is enhanced by a n excellent index.
