ARTS. 

 AN ingenious Artift at Paris has lately completed, with 

 great perfeverance, patience, and mathematical accuracy, 

 a very curious model of that city, on which he has been 

 employed nine years. lie has not contented himfelf with 

 comparing and correcting all the plans of Paris ever pub- 

 lithed : he meafured all theftreets, fquares, &c. according to 

 the mod accurate geometrical methods of menfurement, and 

 determined the inequalities of the lite of that immenfe capi- 

 tal by levelling. The greateft diameter of his mode', in the 

 extent from eaft to well, is fifteen feet. The mean fize of 

 the houfes is throe lines. The artift has carried his accuracy 

 To far, that each inhabitant of Paris can diltinguifh his own 

 houfe, court-yard, and garden. The public places and gar- 

 dens are reprefented v\ ith a moft {hiking fimilitude ; and not 

 only their dimenfions but their colour and ornaments can be 

 cbferved. The alternate rifing and falling of the pl&i.e of 

 the model gives to this reprefentation a correctness which 

 produces an effect like enchantment, if the obferver fup- 

 pofes himfelf to be Handing on Mount-Marte, and to be 

 looking down on the city. The artift has with much judg- 

 ment endeavoured, bv the ihades of his colours, to give a 

 point of reft to the eye ; the want of which is a great failing 

 in that model of Rome which formerly flood in the i 

 of St. Genevieve, and which now belongs to the French 

 nation, as it exhibits the tirefome view of a dazzlit, 6 white 

 mafs of gypfum. Thirty thoufand trees, which difti 

 the different walks, public places, and gardens, fbrni an 

 agreeable variety with the dated and tiled roofs. This model 

 may be taken to pieces by means of fcrews, and can be 

 packed into three large boxes for the purpofe of tranfporta- 

 tion.
