separation, that it is no wonder I should have required some little time to comprehend the meaning of it. In the first place, it is without exception the most marked mathematical forehead I ever met with--being far wider across the eyebrows than either Mr. Playfair's or Mr. Leslie's--and having the eyebrows themselves lifted up at their exterior ends quite out of the usual line, a peculiarity which Spurzheim had remarked in the countenances of almost all the great mathematical or calculating geniuses--such, for example, if I rightly remember, as Sir Isaac Newton himself, Kaestener, Euler, and many others. Immediately above the extraordinary breadth of this region, which, in the heads of most mathematical persons, is surmounted by no fine points of organization whatever, immediately above this, in the forehead, there is an arch of imagination, carrying out the summit boldly and roundly, in a style to which the heads of very few poets present any thing comparable, while over this again there is a grand apex of high and solemn veneration and love, such as might have graced the bust of Plato himself, and such as in living men I had never beheld equaled in any but the majestic head of Canova. The whole is edged with a few crisp dark locks, which stand forth boldly, and afford a fine relief to the death-like paleness of those massive temples.... Of all human compositions there is none surely which loses so much as a sermon does when it is made to address itself to the eye of a solitary student in his closet and not to the thrilling ears of a mighty mingled congregation, through the very voice which nature has enriched with notes more expressive than words can ever be of the meanings and feelings of its author. Neither, perhaps, did the world ever possess any orator whose minutest peculiarities of gesture and voice have more power in increasing the effect of what he says--whose delivery, in other words, is the first, and the second, and the third excellence of his oratory--more truly than is that of Dr. Chalmers. And yet were the spirit of the man less gifted than it is, there is no question these, his lesser peculiarities, would never have been numbered among his points of excellence. His voice is neither strong nor melodious, his gestures are neither easy nor graceful; but, on the contrary, extremely rude and awkward; his pronunciation is not only broadly national, but broadly provincial, distorting almost every word he utters into some barbarous novelty, which, had his hearer leisure to think of such things, might be productive of an effect at once ludicrous and offensive in a singular degree. But, of a truth, these are things which no listener can attend to while this great preacher stands before him armed with all the weapons of the most commanding eloquence, and swaying all around him with its imperial rule. At first, indeed, there is nothing to make one suspect what riches are in store. He commences in a low,
