Forty, designer, engraver, carver, etc., worked in Paris from 1775 to 1780; and in taste and execution his works are perfect examples of the time. In addition to books of vases, iron work for balconies, gratings, stairways, and designs for goldsmiths, he published eight books entitled _Œuvres de Sculptures en bronze_, in which are designs for girandoles, lustres, clocks, candelabra, dials, barometers, etc., and a “design for Two Toilettes,” representing everything that is appropriate to the use of a lady, and ornamented with the proper figures and allegorical attributes. Jewel-boxes, powder-boxes, comb-trays, etc., are included. De Lalonde’s first publications, in the Louis XVI. style, are addressed “to artists and persons who wish to decorate with taste”; and he assures them that everything is in the newest style. They include borders and frames, both square and round, feet for furniture, tables and consoles, doors, cornices, entablatures, girandoles, lustres, candelabra, trophies, soffits, vases, mantel-pieces, over-doors, ceilings and rosettes for ceilings, fire-places, locks and knobs for the use of doors and furniture, chimney-pieces and sconces. His thirteen books of furniture represent sofas, _lits de repos_, _bergères_, duchesses, _banquettes confidents_, ottomans and other varieties of beds and sofas, _fauteuils_ of both the square and gondola form, billiard and card-tables, desks of the cylinder and tomb shapes and desks with hind’s feet, commode desks, commodes of marquetry, square commodes and commodes with hind’s feet, corner-cupboards, screens, chiffonniers, bookcases with pilasters, little toilette commodes, _demi-toilettes_, flower-stands, etc., etc. Other books show numerous designs for the table service. The later publications of De Lalonde approach the new Classic taste. In these there are numerous plates for the decoration of apartments, cornices, consoles, ceilings, doors, alcoves, windows, chimney-pieces, girandoles, lustres, sofas, _canapés_, _fauteuils_ and beds, most of which are “in the antique taste.” Among the chairs there is a _chaise renversée à bergère_, a _fauteuil à griffon_, a _chaise élastique_, a _fauteuil à tête renversée_, and a _fauteuil à chimère antique_. De Lalonde’s designs were exceedingly popular. His beds and sofas _à la duchesse_, _à la polanaise_, _à colonnes_, _à trois dossiers_, _à la turque_, etc. are legion, and his chairs, arm-chairs, _bergères_, screens, tabourets, consoles, etc. appeared at Trianon and Fontainebleau, and many of them survived the Revolution. De Lalonde continued his work under the Directoire and so slavishly followed the fashion that his work leads directly into the style of the Empire as expressed by Percier and Fontaine.
