Dr. Chalmers is not by any means so good a looking man, nor so accomplished a speaker as Mr. Irving; yet he at one time almost equalled his oratorical celebrity, and certainly paved the way for him.  He has therefore more merit than his admired pupil, as he has done as much with fewer means.  He has more scope of intellect and more intensity of purpose.  Both his matter and his manner, setting aside his face and figure, are more impressive.  Take the volume of “Sermons on Astronomy,” by Dr. Chalmers, and the “Four Orations for the Oracles of God” which Mr. Irving lately published, and we apprehend there can be no comparison as to their success.  The first ran like wild-fire through the country, were the darlings of watering-places, were laid in the windows of inns,[A] and were to be met with in all places of public resort; while the “Orations” get on but slowly, on Milton’s stilts, and are pompously announced as in a Third Edition.  We believe the fairest and fondest of his admirers would rather see and hear Mr. Irving than read him.  The reason is, that the groundwork of his compositions is trashy and hackneyed, though set off by extravagant metaphors and an affected phraseology; that without the turn of his head and wave of his hand, his periods have nothing in them; and that he himself is the only idea with which he has yet enriched the public mind!  He must play off his person, as Orator Henley used to dazzle his hearers with his diamond-ring.  The small frontispiece prefixed to the “Orations” does not serve to convey an adequate idea of the magnitude of the man, nor of the ease and freedom of his motions in the pulpit.  How different is Dr. Chalmers!  He is like “a monkey-preacher” to the other.  He cannot boast of personal appearance to set him off.  But then he is like the very genius or demon of theological controversy personified.  He has neither airs nor graces at command; he thinks nothing of himself; he has nothing theatrical about him (which cannot be said of his successor and rival); but you see a man in mortal throes and agony with doubts and difficulties, seizing stubborn knotty points with his teeth, tearing them with his hands, and straining his eyeballs till they almost start out of their sockets, in pursuit of a train of visionary reasoning, like a Highland-seer with his second sight.  The description of Balfour of Burley in his cave, with his Bible in one hand and his sword in the other, contending with the imaginary enemy of mankind, gasping for breath, and with the cold moisture running down his face, gives a lively idea of Dr. Chalmers’s prophetic fury in the pulpit.  If we could have looked in to have seen Burley hard-beset “by the coinage of his heat-oppressed brain,” who would have asked whether he was a handsome man or not?  It would be enough to see a man haunted by a spirit, under the strong and entire dominion of a wilful hallucination.  So the integrity and vehemence of Dr. Chalmers’s manner, the determined way in which he gives himself
