The edifice wherein our Unitarian friends assemble every Sunday, is an old-fashioned, homely-looking, little building--a tiny, Quakerised piece of architecture, simple to a degree, prosaic, diminutive, snug, dull. It is just such a place as you could imagine old primitive Non-conformists, fonder of strong principles and inherent virtue than of external embellishment and masonic finery, would build. It can be approached by two ways, but it is of no use trying to take advantage of both at once. You would never get to the place if you made such an effort. There is a road to it from Percy- street--this is the better entrance, but not much delight can be found in it; and there is another way to the chapel from Church- street--up a delicious little passage, edged on the right with a house-side, and on the left with a wall made fierce with broken glass, which will be sure to cut the sharpest of the worshippers if they ever attempt to get over it. What there really is behind that glass-topped wall we are at a loss to define; but it is evidently something which the occupier of the premises apprehends the Unitarians may have an illicit liking for? If they want to get to it we would recommend the use of some heavy, blunt instrument, by which they could easily break the glass, after which they might quietly lift each other over. Recently, a small sign has been fixed at the end of the passage, and from the letters upon it an inference may be safely drawn that the Unitarian Chapel is somewhere beyond it. To strangers this will be useful, for, prior to its exhibition, none except those familiar with the place, or gifted with an instinct for threading the mazes of mystery, could find out, with anything like comfort, the location of the chapel. Whether the people have or have not "sought for a sign," one has at any rate been given to them here. A small, and somewhat neat, graveyard is attached to the chapel; there are several tomb-stones laid flat upon the ground; and in the centre of it there is a rather elaborate one, substantially railed round, and surmounting the vault of the Ainsworth family. The remains of the late W. Ainsworth, Esq., a well-known and respected Preston gentleman, are interred here.
