From Classical to Modern Chemistry

ganglion cells. Auerbach discovered the myenteric plexus and made fundamental observations on endothelium and on fertilization. The accounts of the four lives are somewhat rambling but are related with warmth and sympathy. Professor Kisch's enthusiasm for his subjects occasionally results in eulogistic passages, but there can be no doubt that he has done well to remind us of how much these men achieved. The biog-raphies are clearly the result of much careful research. Numerous excellent illustrations, thorough documentation, full bibliographies, and an index of names extend the usefulness and significance of this monograph. In this volume Dr. Berry continues the study of the growth of chemical science begun in his Modern Chemtistry. The volume is historical and traces the growth of today's knowledge from the beginnings made in previous centuries. The first chapter is introductory and gives a wide general view of the subject and the mental attitudes its pioneers have had to change or overcome. Energy. Very impressive in the light of today's techniques and equipment are the results and conclusions formed by 18th and early 19th century chemists. Not only did they work in the shadow cast by contemporary scientific giants, but their concept of mathematical analysis left them without adequate tools for a fuller evaluation of their findings. Despite these handicaps, men of all countries contributed, bit by bit, to the general, overall advance of the science of chemistry. If an example were needed to point up the international character of science, then it is contained in this book.
