Mr. Caird's sermon preached at Crathie has been published by royal command. It is no secret that the Queen arid Prince, after hearing it, read it in manuscript, and expressed themselves no less impressed in reading it by the soundness of its views, than they had been in listening to it by its extraordinary eloquence. Our perusal of it has strongly confirmed us in the views we have expressed as to the share which Mr. Caird's manner has in producing the effect with which his discourses tell upon any audience. The sermon is indeed an admirable one; accurate, and sometimes original in thought: illustrated with rare profusion of imagery, all in exquisite taste, and expressed in words scarcely one of which could be allered or displaced but for the worse. But Mr. Caird could not publish his voice and manner, and in warning these, the sermon wants the first, second, and third things which conduced to its effect when delivered. In May, 1854, Mr. Caird preached this discourse in the High Church, Edinburgh, before the Commissioner who represents her Majesty at the meetings of the General Assembly of the Scotch Church, and an exceedingly crowded and brilliant audience. Given there, with all the fkill of the most accomplished actor, yet with a simple earnestness which prevented the least suspicion of anything like acting, the impression it produced is described as something marvellous. Hard-headed Scotch lawyers, the last men in the world to be carried into superlatives, declared that never till then did they understand what effect could be produced by human speech.

A volume just published by Dr. Guthrie of Edinburgh, the greatest pulpit orator of the 'Free Church,' contains many sermons much more likely to interest a reader. The sermon is from the text, 'Not slothful in business; fervent in spirit, serving the Lord.' [Footnote: Romans xii. 11.] It sets out thus:--
