Science in Politics. " Science and Civil 

 Liberty " was the subject of an address by 

 Dr. W. R. Condell at a recent meeting of the 

 Scientific Academy of Springfield, Illinois. 

 Its object was to show the important bearing 

 of the physical sciences on political science, 

 and their claim to be regarded in suggesting 

 and instituting reforms. Accepting Mr. 

 Spencer's principle that the social aggregate 

 must be determined by the units composing 

 it, he derived the corollary that any social or 

 political system, arbitrary in its nature, and 

 not determined by the nature of the units, 

 must be disastrous to the units or individual 

 citizens. The scientific study of the mind 

 from the physical side must have an impor- 

 tant bearing upon the subject of crime as 

 well as on other social questions which have 

 never been solved bv existing methods. 



The metaphysical school, whose deductions 

 rested on a less solid basis than the hard 

 facts of nature, had had too much influence 

 in our legislation. Science, Dr. Condell be- 

 lieved, should be acknowledged as the su- 

 preme political standard ; and not till this 

 result had been consummated would per- 

 fect civil liberty be realized. 



Somnambnlism. The phenomena of 

 somnambulism arise from the fact that the 

 faculties are unequally suspended during 

 sleep, so that one set of organs may be ac- 

 tive while the others are dormant. It is 

 frequently accompanied by dreams, which 

 arise out of a similar condition of the ner- 

 vous functions. Several incidents, illustrat- 

 ing the manner in which the partial suspen- 

 sion, partial activity of the faculties affect 

 the somnambulist, aro- related in an English 

 magazine. A boy, on his way to the sea- 

 side, had traveled by steamer, railway, and 

 coach, from six o'clock in the evening till 

 four o'clock on the next afternoon, without 

 cessation and with hardly any sleep. Short- 

 ly after going to bed, his companion was 

 awakened by a crash of glass, followed by 

 hysterical cries, and, on looking for the boy, 

 found that he had got up, broken the win- 

 dow, and gone. He was found in the road, 

 wounded in the feet. It appeared from his 

 story that, when half asleep, he thought he 

 saw a mad bull rushing at him. Catching 

 hold of the curtain, which he thought was a 

 tree, he swung himself over the hedge by 

 which the tree grew the window, open from 

 the top then jumped and ran away, break- 

 ing the window with his heel, and cutting 

 his feet on the sharp stones. In this case 

 the impression left on the mind of the sleep- 

 walker was so strong as to enable him to 

 tell all that he thought and imagined dur- 

 ing the dream. In the next incident no trace 

 of remembrance survived. A servant-girl 

 came down at four o'clock in the morning, 

 and asked her mistress for some cotton to 

 mend her dress, which she had torn. While 

 she was looking in her work-box some one 

 offered her an empty spool, but she refused 

 it, and taking up her gown pointed to two 

 holes which she said she wanted to mend. 

 A needle was threaded for her with black 

 cotton, but she rejected it, saying she want- 

 ed brown cotton. Some one spoke, and she
