No man ever saw this knocker on the door of a small attorney or bill-broker; they always patronise the other lion; a heavy ferocious-looking fellow, with a countenance expressive of savage stupidity--a sort of grand master among the knockers, and a great favourite with the selfish and brutal.

Then there is a little pert Egyptian knocker, with a long thin face, a pinched-up nose, and a very sharp chin; he is most in vogue with your government-office people, in light drabs and starched cravats; little spare, priggish men, who are perfectly satisfied with their own opinions, and consider themselves of paramount importance.

We were greatly troubled a few years ago, by the innovation of a new kind of knocker, without any face at all, composed of a wreath depending from a hand or small truncheon. A little trouble and attention, however, enabled us to overcome this difficulty, and to reconcile the new system to our favourite theory. You will invariably find this knocker on the doors of cold and formal people, who always ask you why you DON'T come, and never say DO.

Everybody knows the brass knocker is common to suburban villas, and extensive boarding-schools; and having noticed this genus we have recapitulated all the most prominent and strongly-defined species.

Some phrenologists affirm, that the agitation of a man's brain by different passions, produces corresponding developments in the form of his skull. Do not let us be understood as pushing our theory to the full length of asserting, that any alteration in a man's disposition would produce a visible effect on the feature of his knocker. Our position merely is, that in such a case, the magnetism which must exist between a man and his knocker, would induce the man to remove, and seek some knocker more congenial to his altered feelings. If you ever find a man changing his habitation without any reasonable pretext, depend upon it, that, although he may not be aware of the fact himself, it is because he and his knocker are at variance. This is a new theory, but we venture to launch it, nevertheless, as being quite as ingenious and infallible as many thousands of the learned speculations which are daily broached for public good and private fortune-making.

Entertaining these feelings on the subject of knockers, it will be readily imagined with what consternation we viewed the entire removal of the knocker from the door of the next house to the one we lived in, some time ago, and the substitution of a bell. This was a calamity we had never anticipated. The bare idea of anybody being able to exist without a knocker, appeared so wild and visionary, that it had never for one instant entered our imagination.

We sauntered moodily from the spot, and bent our steps towards Eaton-square, then just building. What was our astonishment and indignation to find that bells were fast becoming the rule, and knockers the exception! Our theory trembled beneath the shock. We hastened home; and fancying we foresaw in the swift progress of events, its entire abolition, resolved from that day forward to vent our speculations on our next-door neighbours in person. The house adjoining ours on the left hand was uninhabited, and we had, therefore, plenty of leisure to observe our next-door neighbours on the other side.

The house without the knocker was in the occupation of a city clerk, and there was a neatly-written bill in the parlour window intimating that lodgings for a single gentleman were to be let within.

It was a neat, dull little house, on the shady side of the way, with new, narrow floorcloth in the passage, and new, narrow stair- carpets up to the first floor. The paper was new, and the paint was new, and the furniture was new; and all three, paper, paint, and furniture, bespoke the limited means of the tenant. There was a little red and black carpet in the drawing-room, with a border of flooring all the way round; a few stained chairs and a pembroke table. A pink shell was displayed on each of the little sideboards, which, with the addition of a tea-tray and caddy, a few more shells on the mantelpiece, and three peacock's feathers tastefully arranged above them, completed the decorative furniture of the apartment.
