Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Its prolixity, however, is an obstacle to this work being learnt by heart, except perhaps by some persons who devote themselves exclusively to the study of law, and consequently it appeared to me to be useful to compose an abridgment of it, in length not more than about half of the original volume, but introducing - ii God will - some improve ments.
