In wedding invitations, all abbreviations, like eve. for evening, will be avoided, as well as P. M.; the word afternoon being preferable. Invitations to ceremonious weddings consist of a square note-sheet, embellished with a large monogram in relief, entwining the combined initials of the bride and groom. The individual cards of both bride and groom must be also inclosed, united with a neat white satin tie; and, in some cases, another card, with reception days for the following month. A very neat style of card has the customary 'at home' on a note-sheet, a ceremony card, (at fixed hour,) and the united cards of bride and groom, all enclosed in a splendid large envelope, of the very finest texture, with an elaborate monogram, or ornamental initial. Among the neater forms for a quiet wedding at home is the following: MR. AND MRS.-- Request the pleasure of M.---'s company at breakfast, on Wednesday, December 16, at one o'clock. '--_Hamilton Square_.' Cards of bride and groom must be inclosed for general invitations. Very simple forms are in the best taste. They may be varied to suit the occasion, either of _dejeuner_, dinner reception or evening parties. For example: MRS. WILSON. AT HOME, Wednesday evening, January 7. '--_Fifth Avenue_. 'Cotillion at 9.' Or; Soiree Dansante. MR. AND MRS. E. DAY Request the pleasure of your company on Monday evening, at 9 o'clock. R.S.V.P. An afternoon wedding reception may be announced in terms like the following: MR. AND MRS. HENRY ROBINSON Request the pleasure of your company at the wedding reception of their daughter, on Thursday, October 15, from 2 until 4 o'clock. '--_Maple Grove_.' Or again: MR. AND MRS. RICHARD WILSON Request the pleasure of your presence at the marriage ceremony of their daughter Adelaide to Mr. Jones, at Trinity Chapel, on Wednesday evening, October 5, at 8 o'clock. Reception from 9 until 11 o'clock. '--_West Hamilton street_.' The mode for private dinners may claim a paragraph. Of late, private dinners have been conducted with great ceremony. The menu, or bill of fare, is laid at each plate, an illuminated monogram embellishing the top of the menu. The list of dishes, tastefully written, and a beautifully adorned illuminated card are laid on each plate, to designate the seat of the particular guest. Another style of these cards is plain white, bound with a crimson or blue edge, and has the words _Bon Appetit,_ in handsome letters, above the name of the guest, which is also beautifully written in the same original style, or, perhaps, in fancy colored ink.
