An experiment has been tried on a grand scale with this new and beautiful light, which as an illuminating medium will most certainly take a front place, whether the question is gas or electricity. The immense church belonging to the Oratory of St Philip Neri at Brompton has lately been illuminated by the employment of eight twelve-light, two six-light, and two four-light clusters constructed on this principle; and these have been found so effective, that the interior of this vast and very lofty building is filled with a brilliant, yet soft and subdued, light, which covers the area of the great church. The authorities of the Oratory have expressed their satisfaction at the favourable results of the experiment; and the capability of the Albo-carbon Light has been demonstrated as to bringing out clearly the architectural features of our churches, which, as a general rule, are not celebrated for the excellence of their various systems of gas-lighting. Therefore, any clear and brilliant light which will do this, and at the same time not add too much to the heat of the interior, should be hailed as an inestimable boon, and be one of the chief recommendations of this new and beautiful system. THE LAST OF OLD SION COLLEGE. One by one the old City landmarks are disappearing before the ruthless hand of the modern speculative builder. Many of the City churches have already been taken down and their sites covered with shops or warehouses; Charter House and St Paul’s School are both going; and Sion College is gone—to be opened in a new building on the Thames Embankment, into which the ancient stone front is to be transferred from London Wall. The College, of which all the City vicars and rectors are Fellows, was originally incorporated in 1630, but burnt down in the great fire of London, to be rebuilt shortly afterwards. The site is let for building, but the ancient wooden fittings of the Hall and Library have been sold. The fine library of books will be removed to the new building when complete. IRISH FEMALE EMIGRATION. Mr Vere Foster, of Belfast, has issued another appeal on behalf of his Irish Female Emigration Fund, which has already been the means of granting assisted passages to twenty thousand two hundred and fifty girls from the west of Ireland to the United States and colonies, at an expenditure of about thirty thousand pounds. This scheme has the support—as it should have—of the clergy of all denominations, and there is little doubt that if carefully gone about, it will prove a benefit both to Ireland and the colonies. Mr Foster, who has exhausted what he can spare of his own means and the funds placed at his disposal, has also given assistance by loan to four hundred girls, who have promised to repay him. We trust they may do so, as the good fortune of four hundred more hangs on this contingency.
