THE ANIMAL KINGDOM. 



Divine contrivance, is enabled to perceive external objects. — The eye is a camera ob- 

 fcura, which paints external objects in their juft forms, proportions, and colours. — • 

 The ear is a drum, compofed of a tight membrane ftreached over the cochlea, which 

 gives perception of found, in confequence of tremulous motions excited by the air. — 

 The nose is a broad, convoluted, humid membrane, which arrefts the volatile effluvia 

 which float in the air. — The tongue, befet with little fpongy papillae, attracts fuch 

 fubftances as are applied to it in a ftate of folution. — The fenfe of touch refides in 

 foft papillae, which are fpread every where over the (kin,- and which readily affume 

 the figure of fuch bodies as come into contact with them. 



Moft animals enjoy the ufe of thefe fenfes, though all are not poffefled of every one 

 of them : They might have employed additional fpecies of perception, if it had plea- 

 fed the Creator to endow them with a greater number of fenfative organs ; as the 

 magnet perceives the prefence of iron, and as amber indicates the exiftence of electri- 

 cal phenomena : Antennae are only given to infects, and the ufes of thefe organs are 

 as much unknown to us as thofe of the Ears muft neceffarily be to that tribe of ani- 

 mals. The Eye acts by the agency of light ; the Ear through the influence of air ; the 

 fenfe of Touch is produced by the contact of folid bodies ; the Nofe examines volatile 

 fubftances by means of its nerves ; and, laftly, the Tongue, by its fibrils, attracts fo- 

 luble things, that we may he enabled to judge if they are agreeable, permitted, and 

 fit for ufe ; or whether they be difagreeable, forbidden, and noxious ; and reflection 

 induces us to choofe fuch as are grateful to our fenfes, rejecting thofe which are dif- 

 agreeable.
