This little book aims only at being a very brief and elementary introduction to the Science of Conduct. It has no claim to originality, and is substantially a compilation from those recognised authorities on the subject whose views it reports, and with whose works I hope that it may lead the reader to make acquaintance at first hand. A short Ethical Vocabulary is compiled and a collection of Questions, many of which are taken from published Examination Papers of the University of Cambridge; and have appended the Schedule and list of books recommended for Ethics in the Moral Sciences Tripos.
