2 2 Mr. Henry on the Ccnfijlency of 
fills the mind with aftonifhment. When we 
are informed, that there proceeds more than 
6 ,coo,ooo,ooo,ooo times as many particles of 
light from a candle, in a fecond of time, as the 
whole earth contains grains of fand, fuppofing 
each cubic inch of it to contain i,ooo,oooj when 
we are told that light in its paflage from the fun 
to the earth, moves with the immenfe velocity of 
95 > I 73>°°° > n feven minutes and a half, we 
are impreffed with the mod profound veneration 
for that Almighty Being, who has fo wifely ad- 
jufted the proportions between the bulk and 
velocity of thefe rays, as to make them anfwer all 
his benevolent intentions to mankind whereas, 
an increafe or decreafe in the one or the other, 
might have been fatal to the animal and vegeta¬ 
ble world. 
By the Telefcope and Microfcope our eye is 
enabled to reach far beyond the limits of our 
natural vifion. By the former, objedls, at con- 
fiderable diftances, are brought, as it were, within 
our grafp, and we can loar upwards into other 
worlds. By the latter, we are impowered to 
fearch into the minutiae of nature, to admire the 
delicacy of her operations, and the wonders of 
creation/exhibited in the perfed fabrics of the 
fmallert animals and plants. 
The acquifition of knowledge in the fciences 
which we have already recommended, may per- 
' haps be confidered rather as amufing and orna- 
mental.
