ESSAY XIII 
THE organs or inftruments ufed for commuM- 
cating the fenfes are natural machines, fituated at 
the end of the nerves adj'^ni’ng the brain, for the 
purpofe of reprefenting diflant objeffs. 
ift. The Eye is a Camera Obfciira, or a dark 
ground, that refletls the image of objefts, with 
their proportions, fliape, and complexion, 
2d. The Ear is a drum, ftretched upon a diell, 
joined by a flight ftring, and fluttering with the 
leafl: breath of air. 
3d. The Nofe is a very large, moift, and twifted 
tiflue, attrafling the volatile parts of the air that 
get into it. 
4th. The Tongue is a kind of fponge, that licks 
up and imbibes fuch matter as does not hurt it. 
5th. 1 he Touch, or Feeling, is formed by foft and 
fmall threads, or rufhes, which receive the impref- 
flon of other fubftances. 
Moft living creatures are fupplied with thefe 
organs, but not in the fame degree of perfection. 
Had they been more numerous, we fhould have 
had ftronger faculties juft as the load-ftone attrafls 
iron^
