FOREWORD. THE inspiration of this brochure was the institution of lectures and practical work on Microscopy as part of the class of Medical Physics in the University of Aberdeen. It was felt that a small textbook covering the work of the systematic lectures would be helpful . to the student and might aid him to realize the capabilities, limitations and proper method of use of the instrument. A chapter on the elementary mathematical treat ment of certain problems discussed in the text has been added. It is hoped that the work will prove of value to all students who require a microscope in their studies as well as to those amateur microscopists who wish to understand the fundamental principles on which Microscopy is based.
