10 PRELIMINARY REMARKS. 



on his near side., but to ray great astonishment he refused to do 

 it. After vain endeavors to force him to perform the trick, I gave 

 up and returned to his near side, and at the first command he 

 performed the trick as promptly as usual. If the reader is still 

 skeptical on this subject, we would advise him to make the follow- 

 ing experiment : Take any horse that is very much afraid of a 

 top-buggy, and hitch him to it, putting on a bridle with only one 

 blind, so that he can look back and see the top of the buggy with 

 one eye only. Work on him, hitched in this way, until he is con- 

 sidered perfectly gentle and quiet ; then cut the other blind off of 

 the bridle, letting him look at the top with the eye that has been 

 covered, and he will at once become frightened at the top of the 

 buggy, and attempt to run away. 



This is not so in the human. When man sees an object with 

 one eye only, on looking at the object with the other eye he will 

 say, " that is the same/' and if a boy is taught a lesson at school 

 with one eye closed, when he sees the same lesson with the eye 

 that was closed, he will understand it to be the same lesson. If 

 we want the horse to understand a lesson with both eyes we must 

 educate both eyes. In conclusion on this point, I will state for 

 the benefit of the reader, that the optic nerve crosses or connects 

 between the eyes and the lobes of the brain in the human, while 

 in the horse it goes directly from the near eye to the near lobe of 

 the brain, and from the off eye to the off lobe of the brain, and 

 therefore making no connection between the eyes and the lobes 

 of the brain. 



Another false idea prevails in regard to the Horse's eye, that it 

 magnifies objects to seven times their real size. Hence, a man 

 will appear seven times as large to the Horse as he really is, and 

 this gives man the power to control him. If this was so, when 

 the Horse was eating corn off the ear, or going to bite an apple 

 that was two inches in diameter, he would open his mouth fourtee 

 inches to receive it. Another case in point : let a horse see an
