as to arouse very violent and prolonged bilateral fits, the deflections observed 

 approached in size the smallest of those obtained in the cord. The general results 

 will be seen by the following table, in which the effects observed in the nerve on the 

 opposite (i.e., corresponding) side to the excited cortex of eleven Cats and two Monkeys 

 are separated from those observed in the nerve on the same side. The table is so 

 arranged that the weak fits are given first and the stronger prolonged ones last. 



It will be seen that the amount of deflection varies from a mere trace to 80, the 

 larger readings being always obtained in the case of powerful prolonged and bilateral 

 fits. The average of all the readings in the nerve opposite to the excited cortex is 31, 

 whilst under no circumstances, even with the most powerful fits, is an effect obtained 

 equal in amount to the change evoked in the spinal cord.
