 and especially so with the animal before us. Our 

 further observations place it among those beings 

 on whom nature has bestowed complexity of 

 structure, and relatively high capacities for both 

 use and enjoyment. 



And first, let us remember, our tiny acquaintance 

 is naked and homeless. Nature, however, is kind, 

 and has furnished it with a ready-made brick-
