In this Illustrated Hand-book we have endeavored to incorporate just that kind of matter best suited to both the EXAMINER and the EXAMINED, and to put it in the smallest possible compass compatible with completeness of statement and ample illustration. We have endeavored to be systematic in our arrangment, succinct and clear in our expositions, and popular rather than technical or professional in our style. That this little work may be the means of encouraging the reader to correct any errors of judgement or improper habits he may possess - to cultivate and develop all the higher qualities of mind and heart - and to make the most of his opportunities and of himself, is the desire of the author.
