of Dr. Smith’s pamphlet—­since when, we have heard nothing about Calhoun’s learned argument.  It may be well to remark, that Senator Calhoun read medicine before he read law, and it would have been well for him if he had left medical subjects remain where he left them, for law.  We extract a simple note of explanation without the main argument, to show with what ease the Doctor refutes an absurd argument:  “The reason why the proportion of mortality is not a measure of longevity, is the following:—­The proportion of mortality is a statement of how many persons die in a population; this, of course, does not state the age at which those persons die.  If 1 in 45 die in Sweden, and 1 in 22 in Grenada, the ages of the dead might be alike in both countries; here the greater mortality might actually accompany the greater longevity.”—­Note to page 6.

About three months since, at a public meeting of scientific gentlemen, for the formation of a “Statistic Institute,” Doctor Smith was nominated as one of five gentlemen, to draught a constitution.  This, of course, anticipated his membership to the Institution.  He, for a number of years, has held the office of Physician to the Colored Orphan Asylum, an excellent institution, at which he is the only colored officer.  The Doctor is very learned.

Rev. Samuel Ringgold Ward was, for several years, pastor of a white congregation, in Courtlandville, N.Y., of the Congregational persuasion, and editor of an excellent newspaper, devoted to the religious elevation of that denomination.  Mr. Ward is a man of great talents—­his fame is widespread as an orator and man of learning, and needs no encomium from us.  His name stood on nomination for two or three years, as Liberty-party candidate for Vice President of the United States.  Mr. Ward has embraced the legal profession, and intends to practise law.  Governor Seward said of him, that he “never heard true eloquence until he heard Samuel R. Ward speak.”  Mr. Ward has recently left the United States, for Canada West, and is destined to be a great statesman.

Rev. Henry Highland Garnett, was also the pastor of a white congregation, in Troy, N.Y.  Mr. Garnett is a graduate of Oneida Institute, a speaker of great pathetic eloquence, and has written several valuable pamphlets.  In 1844, Mr. Garnett appeared before the Judiciary Committee of the Legislature at the capital, in behalf of the rights of the colored citizens of the State, and in a speech of matchless eloquence, he held them for four hours spell-bound.

He has also been co-editor of a newspaper, which was conducted with ability.  As a token of respect, the “Young Men’s Literary Society of Troy,” elected him a life-member—­and he was frequently solicited to deliver lectures before different lyceums.  Mr. Garnett left the United States in the summer of 1849, and now resides in England, where he is highly esteemed.
