The present title Encyclopaedia of Research Mathodology has been carefully compiled and edited to meet the long felt needs of increasing number of students and researchers who have to deal with habits, behaviour, collection, reproductive biology, care and management of laboratory animals and preparation for microscopic studies including microscopes, instruments of staining processes. It is one of the few books that give a practical introduction to the husbandry of laboratory animals for use both by research workers and technicians involved. It will also be needed for students of reproduction in agriculture, veterinary, medicine, zoology and the biomedical sciences. The material presented in the following pages will afford the student and researcher in the subject a comprehensive view and appropriate background material for focused studies. It is our earnest hope that this book will be of great value to all our students.

The present book is a comprehensive uptodate textbook. This is an indispensable text meeting complete requirements of undergraduate and postgraduate students of Zoology. It has been designed to approach the morphology, anatomy, physiology and development of selected type in a very simple and lucid style. According to the scheme of treatment the important animal types of each phylum have been dealt with first, and efforts have been made to present their elaborate and uptodate account. In the description of animal types special emphasis has been laid on the functioning of organs. General characters and classification and brief description of other important types of the phylum have also been dealt with complete authentic and uptodate account. Separate chapters on topics of significance and general interest pertaining to the phylum have been also added to make the treatment more elaborate. Adaptations of animal type have been discussed in detail to reveal their relation with the environment. It has been the constant endeavour of the authors to furnish maximum substance, keeping in view the limitations of size of the volume. Efforts have been made to condense, the matter as far as practicable. The book features both a text and a laboratory guide. It is hoped that this book will not only meet the requirements of Indian students but will also be useful as a guideline to the teachers in their teaching.
