TO THE

REV. GEORGE HARRIS,

OF GLASGOW,

SECRETARY AND TREASURER TO THE SCOTTISH UNITARIAN CHRISTIAN ASSOCIATION, EDITOR OF THE CHRISTIAN PIONEER,

&c. &c.

Rev. and very DEAR SIR,

I dedicate this humble, but, I trust, useful pamphlet, to a man so eminently distinguished as you are, without any wish to make you responsible for the statements and views which it contains. I only desire to express the admiration which I feel, in common with all who know you, on account of your many noble and amiable virtues; your powerful, impressive, commanding eloquence; and your constant and untiring zeal to disseminate just views of God, of man, of moral duty, and of future happiness. I wish also to declare, in this public manner, the sincere and intense affection which I cherish towards you, and must continue to cherish throughout life, for the blessings which I derived, as an inquirer after truth, from my attendance on your ministry; and for many other valuable favours which I have since received, however undeservedly, at your hands. If God should continue my existence, and give me success in the advocacy of truth and virtue, it will be my happiness to acknowledge in what school I have been taught; and always to make mention of your name in terms of the highest veneration, esteem, and gratitude.

I have the honour to be,

REV. AND VERY DEAR SIR,

Your affectionate friend,

And most obedient faithful servant,

JAMES FORREST.
