Perfpedlive is principally necefTary in regular 

 buildings, where many ftraight lines run through 

 the various parts of them, of which all that 

 are parallel muft: meet in one point. In other 

 fubjeils a thorough knowledge of perfpeélive is 

 not fo abfolutely necelTary ; yet a due regard for 

 it is always to be had ^ as in landfcapes, to di- 

 minifh every thing according to its fuppofed 

 diftance from the eye \ for, by making the dif- 

 tant figures the leail, and drawing them in finer 

 or fainter lines than you do thofe that come 

 forwards in your piélure, they naturally feem to 

 be more diflant ; and when you come to finifli 

 fuch pi6ture, your extreme diflant objeds fhould 

 appear fo faint, or fo fecure, as not to hû difcô- 

 vered to be of any precife form or colour ; fbr 

 fo it is in natural objeds far diflant from our 

 fight. As objects draw nearer they m^y be 

 made a little more exprefTive ; and fo on, more 

 and more, till you come to the nearefl objeds 

 of all in the fore- ground of the pi6lure, which 

 fhould be finifhed with great flrength^ and 

 brighter colouring : for it mufl always be con-* 

 fidered, that fuch objects as have really in them- 

 felves a very bright colouring, if they are re- 

 moved
