Thus animals that are not appointed to live together, 

 may notwithstanding form a sort of society : the natural 

 inclination each of them has to live with those of a like 

 kincl, is susceptible of modification or extension. 



Every individual knows his like ; those of the same 

 society likewise know them. It is observable, that if 

 strange fowls are brought into a poultry^yard, those of 

 the place will persecute them, till cohabitation has 

 made them members of the society. 



The outside of the body exhibits divers characters, 

 by means of which individuals of the same society may 

 know each other, and distinguish strange individuals. 

 But among these physical characters there may be some 

 mixed ones, or such as belong as much to the soul as 

 the body, which the animals of the class we are treating 

 of, are capable of seizing ; such are the air, pdlture, 

 gait. The individuals of that species, which are not 

 yet become familiar in their new habitation, seem fear- 

 ful or embarrassed : this fear or embarrassment de- 

 tects them, and excites or encourages others to attack 

 them. 



That kind of society in which domestic animals live, 

 gives room for a remarkable observation ; the young 

 lamb distinguishes her mother from amongst 3 or 400 

 sheep, although there does not appear to be any sensi- 

 bk difference betwixt them. 



0; Nothing is more wonderful than those legions of 

 flying creatures, that at a stipulated time pass from one 

 to other very remote countries. What instinct assembles 

 them ? What compass directs them ? What chart 

 points out their way ? We presently conceive that the 

 change of the season, and the want of suitable nourish- 

 ment, advertise these different species of birds to shift 

 their abode. But whence did they learn that they 

 Should meet with, in other regions, a climate and 

 aliment proper for them ? la order to be able to 

 answer these questions, and all such as may be asked on 

 this interesting subject, we should carefully examine
