ARCHITECTURE is a fcience, fome of whofeprin-
ciples we have elfewhere confidered. It requires an union
of many very valuable ftudies to make an expert prac-
tical Architect : geometry, accuracy in calculation,
knowledge in the value, and employment of Materials.,
the multiplied manners of preparing them, the pro-

when they are well ufed, and forefight to determine
their probable effect: tafte to formluch ornamental erec-

othenvife, accurate meafures could not be adapted.
Moreover to render fenfible the receflions of diftancess
though butfmali, a tint of colour fomewhat ftronger than
nature would juftify,is pardonable, if it be not extreme.
Atfo an architectural drawing may fhevv a geometrical
plan, elevation and feclion, together with parts of the
fame in perfpeclive, where no invincible obflacles forbid.

understanding of the defign, are tolerated in architecture,
though not juftified by Uriel perfpeclive.
