To those who have given a trial of the Superior Boots and Shoes manufactured with DICK's Patent Elastic Metallic Shanks, information would be needless; for they could not be induced to purchase elsewhere. But we would respectfully ask attention of the entire Boot and Shoe wearing community, to call at 100 NASSAU street, being assured that it gives the proprietors great pleasure to impart every information for the ease and comfort of the UNDERSTANDING, and also with regard to their entirely new mode of taking the measure of the foot, to give an equal pressure on every part.

GOLD PENS!!—In consequence of the increased facility afforded by machinery for the manufacture of my GOLD PENS, I am enabled to furnish them to the Trade, at a much less price than they have heretofore obtained them through my Agent.

Those purchasing direct of the manufacturer will have the double advantage of the lowest market price, and the privilege of returning those that are imperfect. In connection with the above, I am manufacturing the usual style of PENHOLDER, together with my PATENT EXTENSION PENHOLDER with PENCIL. All orders thankfully received, and punctually attended to. A. G. BAGLEY,

SHERWOOD'S MAGNETIC MACHINE.—Is warranted to be greatly superior to every other manufactured, by whatever imitations or pretensions foisted upon the public. No premium has ever been obtained over this machine at the American or any other Institute, as has been falsely represented. It imparts the magnetic forces more continuously, with less violence to the sensations of the patient, and with more permanent efficacy, than any other invented, while the cures it has actually effected are incomparably more numerous. It is compactly fitted, together with its battery, wires and other appliances in neat cases, of several sizes, and powers, at $10, $12, $14, and $16 each. Each case is accompanied with a Manual, (eighth edition, pp. 234, 8vo.) in the English or French language, according to order, containing specific direction for the new method of using the instrument, and which alone can render it effectual.
