Excerpt from Problems and Methods of Research in Protozoölogy Certain protozoa are of great importance to medical men, espe cially those interested in tropical medicine, and to veterinarians since these organisms may be pathogenic parasites of man or domesticated animals. Hence we find that diseases in man and other animals due to these protozoa are being investigated in medi cal and veterinary schools. In, these investigations attention is directed primarily to the effects of the parasitic invasion on the host and the studies of the parasites themselves are undertaken with particular reference to their relations to the host.

Excerpt from Protozoa in Biological Research Numerous textbooks of varying degrees of excellence for the study of Protozoa are now on the market and should be consulted for a general treatment of these unicellular forms. This volume will not fill such a need, but has been prepared as a result of a discussion by a group of specialists assembled during the summer of 1937 at the Marine Biological Laboratory at Woods Hole, Massachusetts, for the purpose of ascertaining the best means to stimulate further research on these unicellular animals. As a result of these discussions it was decided that one good way to attain our end would be to have a group of specialists in the field Of protozoology prepare a work on research in this field, each specialist to provide a chapter on the subject in which he is best known, and about which he can speak with authority. Our first real difficulty was to select a limited number of topics from a vast number of possibilities, and then to choose the biologists who, in our opinion, were the best men to write these chapters. As can be readily imagined, this opened up a long list of difficulties and led to many vexatious troubles, but the present work, finally, is the Outcome.

Excerpt from Protozoology HE present work is similar in its primary aim to that of its predecessor, Handbook of Protozoology in presenting introductory information on the common and representative genera of all groups of both free-living and parasitic Protozoa, to advanced undergraduate and graduate students in zoology in colleges and universities. With the expansion of courses in proto zoology at the University of Illinois and elsewhere, it seemed ad visable to incorporate more material for lecture and discussion, in addition to the enlargement of the taxonomic section. The change of the text-contents has, therefore, been so extensive that a new title, Protozoology, is now given. Chapters 1 to 6 deal with introduction, ecology, morphology, physiology, reproduction, and variation and heredity, of Proto zoa. Each subject-matter has been considered in the light of more recent investigations as fully as the space permitted. Selection of material from so great a number of references has been a very difficult task. If any important papers have been omitted, it was entirely through over-sight on the part of the author.

Excerpt from Handbook of Protozoology With regard to their habitat, the Protozoa may be divided into free-living forms and those living on or in other organisms. The vegetative, or trophic, stages of free-living Protozoa have been found in every type of fresh and salt water, in soil and in decaying vegetable matter. While the freshwater inhabiting forms are ordinarily unable to live in salt water, and vice versa, seemingly one and the same species has, in a number of cases, been found in both fresh and salt waters.

Excerpt from Protozoölogy There is need, furthermore, of caution in studying protozoa under such artificial conditions, for they are extremely sensitive to variations and are readily adapted to new conditions. The reactions, both morphological and physiological, of protozoa under such conditions of study require careful control. The study of protozoa, therefore, even when it is possible to apply bacteriological methods, is fundamentally different from the study of bacteria as at present carried on. The latter, dependent upon growth conditions, colony formation, reactions to media, etc., are essentially physiological and based upon the functions of the organisms. The study of protozoa, on the other hand, is essentially morphological, or based upon the structures of the protozoan cell, and involves the changes in cell structures which an individual undergoes during various phases of vitality. Hence it becomes necessary, first of all, to know the life history of the protozoon and the fundamental modifications which its protoplasm assumes. Modern protozoology, therefore, has demanded as a basis for genera and species of protozoa a knowledge of the complete life cycle, and as a basis for classification not the strue tures of the single cells, but the structures which the protoplasm may assume throughout its entire life history from fertilization to death or until the next fertilization. The present volume, finally, does not aim at being an exhaustive treatise on the protozoa; it aims, rather, to give an introduction to the study of modern protozoo'logy as seen from the author's point of view; and for numerous omissions, incomplete references, etc., he can only plead the excuse of a large subject crowded into a limited space.
