Of this denomination, there are about three hundred churches and congregations in the United States, and near that number of ministers. In the city of Boston it is one of the most numerous and influential classes of Christians, having eighteen societies, most of which are large and flourishing. In the Middle, Southern, and Western States their congregations are fewer, but gradually multiplying.

Periodicals.—The Christian Examiner, the Monthly Miscellany, and the Christian Register, are published in Boston, Mass.

A favorite project of Christian philanthropy with the Unitarians has been the “ministry to the poor” in large cities and towns. They have established such an institution in Boston, New York, Cincinnati, Louisville, Providence, and elsewhere. In Boston, three large and commodious chapels have been erected, and three ministers constantly employed, by the aid of funds obtained from individual donors and annual subscriptions from associations in the several churches of the denomination.
