as so suspended being 3 lbs., the additional downward pull 

 was therefore 3J lbs. On looking immediately afterwards 

 at the automatic register, we saw that the index had at 

 one time descended as low as 9 lbs., showing a maximum 

 pull of 6 lbs. 



In order to see whether it was possible to produce much 

 effect on the spring balance by pressure at the place where 

 Mr. Home's fingers had been, I stepped upon the table and 

 stood on one foot at the end of the board. Dr. A. B., who was 

 observing the index of the balance, said that the whole weight 

 of my body (140 lbs.) so applied only sunk the index ij lbs., 

 or 2 lbs. when I jerked up and down. Mr. Home had been 

 sitting in a low easy-chair, and could not, therefore, had he 

 tried his utmost, have exerted any material influence on 

 these results. I need scarcely add that his feet as well as 

 his hands were closely watched by all in the room. 



This experiment to me appears, if possible, more striking 

 than the one with the accordion; As will be seen on 

 referring to the cut (Fig. 3), the board was arranged per- 

 fectly horizontally, and it was particularly noticed that Mr. 

 Home's fingers were not at any time advanced more than

1^ inches from the extreme end, as shown by a pencil-mark, 

 which, with Dr. A. B.'s acquiescence, I made at the time. 

 Now, the wooden foot being also ij inches wide, and resting 

 flat on the table, it is evident that no amount of pressure 

 exerted within this space of if inches could produce any
