POPULAR SCIENCE MONTHLY. 



strict application of the law of priority. 

 One of the objects of the authors has been 

 to define a method by which the recognition 

 of antecedent work can be consistently se- 

 cured. They propose that this rule be desig- 

 nated as " Merton rules " for convenience of 

 reference. 



Convinced that physical science awaits 

 its next greatest elucidations from the side 

 of biology, Dr. Ernst Sfach has made from 

 time to time various researches on sensation, 

 the results of which he states in a volume 

 under the title Contributions to the Analysis 



of the Sensations (Open Court Publishing 

 Company, $1.25). He here discusses the 

 space sensations of the eye in connection 

 with the innervation of that organ and the 

 physiological aspects of sensations of time 

 and sensations of tone. The conclusions 

 which he has arrived at on these topics 

 show, he affirms, that "there is no rift be- 

 tween the psychical and the physical, no 

 within and without, no sensation to which an 

 outward, different thing corresponds. There 

 is but one kind of elements, out of which 

 this supposititious within and without is 

 formed."
