Excerpt from Colloids in Biology and Medicine This book is an attempt to apply the results of colloid research to biology. The reader may find the undertaking somewhat bold, since the number of facts are so few, and the gaps so numerous that a complete picture is impossible. I find myself somewhat in the position of a palaeontologist who wishes to reconstruct the ancestry of the entire organized world from some chance fragments. Each day brings new finds which must be fitted into his plan and which confirm his views or show that he has been on a false trail. From the nature of things, it happens that I must more often indicate problems than report experimental results. This probably will prove a stimulus to those who wish to take active part in the development of our young science. I wish to state one additional fact: it was not my purpose to make this book exhaustive. I have endeavored to give a general view, and since the work is addressed to biologists and physicians as well as colloid investigators, I have striven to give a clear picture of the subject, disregarding moot questions. - On this account the "Introduction to The Study of Colloids" was abbreviated as much as possible without danger of obscuring the subsequent parts. - Those who wish to stud more thoroughly pure colloid chemistry, I refer to the excellent books of Herbert Freundlich "Kapillarchemie" Leipzig, 1909, and Wolfgang Oswald "Grundris der Kolloidchemie," Dresden. Accordingly, in the arrangement of the first part, I have not followed the usual system, but have been guided by a desire to make easy of comprehension the matters most important to biologists and physicians. On this account I have considered it advisable to devote considerable space to the "Methods of Colloid Research." Some new unpublished experimental data of my own and some placed at my disposal by others have been included. It is finally my privilege to thank all those who have helped me in the preparation of this book, particularly Professors H. Apolant, R. Hober, H. Sachs, and Dr. H. Siedentopf.
