890 Dynamic Theory. 



the inertia of even the most delicately constructed electric instruments. 

 The disturbance of the tensions must be enough to enable the straining 

 ethereal element to carry with it the heavy metallic armature. The del- 

 icacy of the adjustments of the cerebral receiving organs must be in- 

 finitely finer than this. 



The following is told and vouched for by Abercrombie : "A lady in 

 Edinburgh had sent her watch to be repaired. A long time elapsed 

 without her being able to recover it, and after many excuses she began 

 to suspect that something was wrong. She now dreamed that the watch- 

 maker's boy, by whom the watch was sent, had dropped it in the street 

 and injured it in such a manner that it could not be repaired. She then 

 went to the master, and without any allusion to her dream, put the ques- 

 tion to him directly, when he confessed that it was true." 



Another singular case which Abercrombie cited as true, is as follows: 

 A young man at an acadamy a hundred miles from home, dreamed that 

 he went to his father's house in the night, tried the front door but found 

 it locked, got in by a back door and went to the bedroom of his parents. 

 He then said to his mother whom he found awake, ' ' Mother, I am go- 

 ing on a long journey and have come to bid you good-by. " On this she 

 answered under much agitation, " Oh, dear son, thou art dead." As was 

 afterwards ascertained his mother dreamed the same dream at the same 

 time, the particulars of someone trying first the front door, then enter- 

 ing by the back door, of the person whom she then recognized as her 

 son approaching her bed, and using the same language, and her reply 

 being the very same as in the son's dream. The dream gave the mother 

 much alarm, but nothing unusual happened to either of the parties. 



This curious occurrence cannot be explained as a mere accidental co- 

 incident. In fact. I cannot imagine any possible explanation which 

 does not involve the projection of nervous influence to a distance. We 

 may suppose a high degree of sameness or identit} r between the two or- 

 ganizations, which is sensible to us under the name of sympathy. All 

 organizations which have been exposed to the same stimuli are obviously, 

 to a certain extent, identical in constitution, so that whatever form of en- 

 ergy is able to excite one of them, will excite the other, if by any means 

 it can reach it; and whatever form of energy is developed in one, if by 

 any means we may suppose it projected into the field of force belonging 

 to the other, it will develop in it a movement precisely like that which 

 took place in the first. The two nervous organizations stand to each 

 other in the very same relationship as two connected dynamos, one of 

 which is driven by a steam engine, while the other is operated by the 

 current from the first, and in turn drives some sort of machinery, as a 

 printing press or a street car. 



The following is another instance : < ' Columbus, Ohio, Jan'y 3.
