A correspondent of the _Weekly Register_, writing to show the increase of Catholicism in London during the last thirty years, points out that in 1839 there were in the metropolis and the suburbs the following Catholic churches:—St. Mary’s, Moorfields; St. Mary’s, Chelsea; the French Chapel, King Street, Portman Square; the Chapel of the Benedictine Convent at Hammersmith (now removed to Teignmouth, Devonshire); St. Mary’s, Kensington; St. Anselm’s, Lincoln’s Inn Fields; St. Patrick’s, Soho; St. Aloysius, Somers Town; St. James’s, Spanish Place, Manchester Square; and the Assumption, Warwick Street, Golden Square; in all ten churches or chapels. There are now, in addition to the above, St. Mary and the Angels, Bayswater; the new church at Bow; the Oratory, Brompton; St. Bridget, Baldwin’s Gardens; St. Joseph, Bunhill Row; the Servite Fathers, Chelsea; St. Peter’s, Clerkenwell; SS. Mary and Michael, Commercial Road; the Immaculate Conception, Farm Street; St. Thomas, Fulham; the German Church, Whitechapel; the church built by Sir George Bowyer, in Great Ormond Street; St. John the Baptist, Hackney; Holy Trinity, Brook Green; Nazareth House, Hammersmith; the chapel at Hampstead; the Dominicans’ Church, Haverstock Hill; the Passionist Church, Highgate; the Augustinians’ Church, Hoxton; the Sacred Heart, Holloway; St. John the Evangelist, Islington; the Italian Church, Hatton Wall; the Carmelite Church, Kensington; the church in Kentish Town; the church at Kilburn; Our Lady and St. Joseph, Kingsland; the new French Church, Leicester Square; the Rosary, Marylebone Road; St. Francis, Notting Hill; St. Charles, Ogle Street; the Polish Chapel, Gower Street; St. Mary’s, Poplar; the Holy Family, Saffron Hill; St. Anne’s, Spitalfields; Our Lady’s, St John’s Wood; St. Vincent de Paul, Stratford; the English Martyrs, Tower Hill; Our Lady of Grace, Turnham Green; St. Mary’s, Horseferry Road, Westminster; and SS. Peter and Edward, Palace Street, Westminster—in all forty churches or chapels in thirty years (without counting many private chapels or convents, &c.), or fifty chapels, where thirty years ago there were but ten. And it should be borne in mind that of the new churches many, such as the Oratory, Commercial Road, Farm Street, Islington, the Italian Church, Bayswater, Brook Green, St. John’s Wood, and others, are of a size and beauty which thirty years ago would have been deemed a folly even to hope for. There are now as many masses said at the Oratory, Bayswater, and Farm Street, as thirty years ago there were in all the chapels in London, so great has been the increase of priests in London since 1839. On the south side of the water, in the diocese of Southwark, the change for the better is even more manifest than in that of Westminster; but, the congregation being poorer, the churches are also smaller. In what is now the diocese of Westminster, there were, in 1839 (writes the same correspondent), about seventy
