 upon the raw material of sensation furnished to it 

 through the eye, and gives rise to a train of 

 thoughts. First comes the thought that there is 

 an object at a certain distance ; then arises

 succeeded by another thought of the nature of an 

 emotion namely, the desire to possess the hare ; 

 then follows a longer or shorter train of other 

 thoughts, which end in a volition and an act the 

 loosing of the greyhound from the leash. These 

 several thoughts are the concomitants of a process
