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.
