to try the following experiment. He induced a Brama hen to 

 hatch out an egg from a peacock. Although it is a general rule of 

 the hens to reject their young ones as soon as they are capable to 

 take care of themselves, this hen rendered undivided attention and 

 care to that young peacock during a lapse of time of eighteen 

 months. During all this time the hen did not lay one egg. More- 

 over, a very peculiar feature to be considered, this hen, like other 

 hens of peacocks, picked and tried to straighten out the plumes 

 and the tuffs on the head of the young peacock ; and, in order to 

 perform this transaction conveniently, she mounted herself on a 

 higher and suitable object to reach his head. The peacock then 

 placed himself in front of her, bending his head forward, and the 

 hen began to pick and straighten the tuffs with greatest care. 



Now, in this strange case, there was not any form of an 

 inherited faculty present, as gesture or other forms of demonstra- 

 tive expression, which would induce the hen to act in compliance 

 with the habits of peacocks. Hence, it is obvious that the hen 

 must have been reasoning intuitively from the transcendental 

 being of the young peacock ; that is, the hen was reflecting upon 

 the instinctive emotional effect (motive), the pleading to be cared 

 for ; finally, these intercurrent feelings established an understand- 

 ing, which resulted that is, the hen was induced to act here as a 

 fostermother. 



A much more peculiar case of an alliance is exhibited where 

 two organic beings, of two extremely distinct species, join for the 

 benefit of their mutual welfare. There is the hermit crab, which, 

 according to his tender and delicate anatomical organization, is 

 compelled to seek shelter in a vacant shell, merely using it for a 

 tenement. But the weight of the shell retards his locomotion in 

 the pursuance of prey. What does he? He forms an acquain- 

 tance with a sea anemone (sargatia parasitica) and induces her 

 to ally with him and mount herself on his tenement, near the edge 

 of the shell. The anemone prefers frequently current waters, and 

 this she will find when she joins the crab. Both are carnivorous 

 individuals, The tentacles of the anemone, searching and reach- 

 ing out for prey, will always gather sufficient food for both. The 

 anemone has thereby the opportunity, when the crab slowly 

 moves to other places, of a new field for prey ; this again impels 

 the crab, in order to receive new food, to maintain its mobility.
