Excerpt from Colloid Chemistry of the Proteins, Vol. 1: With 27 Diagrams and Numerous Tables The small volume of which Part I. Is here presented has been developed from lectures delivered in the winter term of 1912 - 13. It by no means exhausts the materials of the colloid chemistry of the proteins even up to that date. In response to many requests, it is proposed to collect in perspective the investigations carried out by the author and his co-workers in'the course of many years, prominence being given to the most important results. Such fundamental work of other authors as is relevant has also been included in an attempt to round off the presentation, but for complete data the reader is referred to the well - known works of O. Cohnheim, R. H. A. Plimmer (translated into German by J. Matula), and T. B. Robertson. The second part, to appear within a year, will include the relations of the proteins to neutral salts and to the salts of the heavy metals, to colloids and to ampholytes, the properties of the albumin gels, and, finally, the physical chemistry of the purest albumin so far prepared. I take this opportunity of thanking most heartily Dr. Mona Adolf for her careful and critical reading of the proofs, and also my assistant and collaborator of many years, Dr. Joh. Matula, for drawing the figures. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
