gufting even in thofe who have moft reafon 
to be proud ; what then muft it not be in 
thofe who have no pretenfion to eminence?

fome difficulty in drawing a flraight line 
between them, becaufe moft arts require 
fome degree of Science : neverthelefs, by the 
.help of an example or two, we (hall pofli- 
bly be able to feperate the two ideas, fo as to 
keep them tollerably diftincT:.
