Introduction.

In consenting to the publication of this Lecture by the Society in connection with which it was delivered, I feel that my only claim to the consideration of the public is, that my subject is one which I have not lightly treated; one to which I have given much earnest thought and attention which I have chiefly studied in the pages of those who have argued on "the other side" one on which my views have not been hastily formed, nor will he found, I hope, to be extreme; and one of so great importance, that if" any thoughtful man believes he can advance anything which may assist the public in coming to a just conclusion in regard to it, he stands in no need of apology for for doing so.

With which preface I commend this brief contribution to the controversy to the candour of my fellow-colonists.
