in short, it can only be regarded as an assemblage of masses, 
without any general or particular connexion, 
Thus, eacly of these arts, residing within bounds prescribed 
by nature, ought to keep to its adv antages, and surmount its de- 
fects by touches mutually borrowed. Painting, notwithstanding 
the grandeur and abundance of its means, always endeavours to 
produce the effect of reliefs, and thus to imitate sculpture. The 
latter, confined to solid matter, cannot be susceptible of har- 
mony and opposition, except from the variety of the workman- 
ship of the chisel, and by the more or less ‘of decision in the 
shading: it cannot draw this harmony from any thing but from 
itself, or, what is absolutely the same, from the mere colour of 
the matter upou which it works: in order to please, it seeks the 
harmony of painting :—both arts, therefore, mutually lend each 
other assistance. In this case they are sisters; but they are dif- 
ferent in their methods of attaining the same end, and they can- 
not reside under the same roof. 
It results from these reflections, founded on the essence and 
the detail of the two arts, that the sculptor, having less assist- 
ance, seems to have more merit when he arrests and astonishes 
the spectator, to make him feel all the grandeur of a great ac- 
tion : but at the same time the spectator requires a great variety 
of lights to judge by; and consequently painting, being more 
adapted to the capacity of all men, and flattering their idleness 
more, must necessarily have more friends and a ereater number 
of partisans.

“ Of the Decomposition of Water*.” 
" Tue antiphiogistic theory has received its greatest support,” 
says Dr. Priestley, **from the supposed discovery that water is 
resolvable into two principles; one that of oxygen, the base of 
dephlogisticated air; and the other, because it has no other origin 
than water, hydrogen, or that which with the addition of ca- 
lorique, or the element of heat, constitutes inflammable air. 
‘One of the parts of the modern doctrine the most solidly esta- 
blished,’ say M. Berthollet and the other authors of the Re-
