PRINCE FREDERICK WILLIAM CHARLES, OF PRUSSIA, died at Berlin on the 28th September. He was a brother of the late Frederick William the Third, uncle of the present King, and the youngest legitimate son of Frederick William the Second. He was born at Potsdam on the 3d of July, 1783. He served actively in the army during the war with France, which terminated so disastrously at the battle of Jena. He was also present at the battles of Katzbach and Leipsic, and subsequently at Waterloo commanded the reserve cavalry of the fourth corps of the Prussians. Gentlemen's and Ladies' Fashions for December. In the fashionable world of this country we have at length the long-expected "hat of the future," from the ingenious artist GENIN, who appears to be the only American who brings to the manufacture of hats an inventive faculty. It is likely that these hats will gradually take the place of the funnel and stove-pipe styles which have been so long in vogue. They are made of fine material, are light, pliable, durable, and have the more important merit of elegant and picturesque appearance. They are indifferently styled the _Union Hat_, and the _Grandison Hat_--the last name referring to the ideal of Queen Anne's days. [Illustration] It is much doubted whether any of the changes made in gentlemen's costume in the last half century are improvements, and there are very few persons of taste who will approve the hat of the last few years more than that worn in the good old times of General Washington, when the three-cornered chapeau began to give place to such hats its are represented in our illustration. [Illustration] The next is somewhat more in vogue, at least for younger men, and for the opera and the theatre. It sets off a fine-looking face advantageously. [Illustration] The last is better suited for travelling or hunting. In Ladies' Fashions, there are some novelties, though comparatively few of a kind to attract a large degree of attention. We select for illustration in the first place-- [Illustration] _Close Under-sleeve._--This sleeve will be found to be of a very desirable form by ladies who object to the open sleeves, as it combines the elegant effect of the latter with the comfort of the close sleeve. It may be made either in muslin or net, and is cut as a bishop's sleeve, the fulness being confined on a band at the wrist. Two broad frills of lace or needlework are attached to the lower part of the sleeve. These frills are open in front of the arm. [Illustration] _Under-sleeve of Lace._--This sleeve is intended to be worn for evening dress. The double row of vandyked lace forming the trimming should drop below the sleeve of the dress, under which the lace sleeve is to be worn.
