remarkable preacher whose blindness and eloquence have been celebrated by Mr. Wirt in _The British Spy_. In the Autumn of 1806 he received a call from the Third Presbyterian Church, at the corner of Pine and Fourth-sts., in Philadelphia. Though he had declined an invitation to the same church ten years before, he accepted this, and thus became a second time the successor of the Rev. John Blair Smith, D.D. He continued at this post until, in the spring of 1812, he was summoned by the General Assembly of the Presbyterian Church to be the first Professor in the Theological Seminary then just founded at Princeton. This chair, we believe, he occupied until his death--until within a few weeks, at least, discharging all its honorable duties. It is a pleasing fact that the first two Professors in this Institution were associated in its service nearly forty years. During this period a large number of clergymen have proceeded from the seminary, and it has now not far from one hundred and fifty students. It is important to observe that it has no connection with the College of New Jersey, at the same place. The eminent usefulness of Dr. Alexander is not to be measured by the long and wise discharge of his duties as a professor. He was a voluminous, very able and popular writer. In addition to occasional sermons and discourses, and numerous smaller treatises, he wrote constantly for _The Princeton Review_, a quarterly miscellany of literature, and theological and general learning, of the highest character, which is now in the twenty-seventh year of its publication. His work on _The Evidences of the Christian Religion_ has passed through numerous editions in Great Britain as well as in America, and this, as well as his _Treatise on the Canon of Scripture_, which has also been republished abroad, we believe, has appeared in two or three other languages. The substance of the latter has, however, been incorporated with more recent editions of the former, under the title of _Evidences of the Authenticity, Inspiration and Canonical Authority of the Holy Scriptures_, of which a fifth edition--the last we have seen--was published in Philadelphia in 1847. Among his other works are _Thoughts on Religion; a Compend of Bible Truth_; and a _History of Colonization on the Western Coast of Africa_--the last an octavo volume of more than six hundred pages, published in Philadelphia in 1846. His principal writings, however, have been on practical religion and on the History and Biography of the Church, and these for the most part have been published anonymously. Dr. Alexander was the father of six sons, of whom three are clergymen. The eldest, James W. Alexander, D.D., for several years Professor in the College of New Jersey, and sometime Pastor of the Duane-street Church in this city, is a fine scholar and an able preacher, and has enrolled himself among the benefactors of the people by many writings of the highest practical value designed
