It is not presumed that this Volume contains rules for every probable or possible contingency in which the inquirer may seek for the application of the Deontological code. But the principles being laid down, and so many incidents offered for their explanation and illustration, the reader may be safely left for himself to gather together such circumstances as his observation may furnish, in order to submit them to those tests with which he is here supplied. In doing this, he will forward the views of that wise and benevolent Philosopher to whom these pages owe their birth.
