water around the nucleus deprived of the sugar ; this portion of the 

 water would attract its portion of sugar from the layer without, and 

 into this layer the sugar from the layer next without would be dif- 

 fused, and so on until, through all the water, the remaining sugar 

 would be uniformly diffused. The process would continue to be re- 

 peated, by the nucleus again attracting a portion of the sugar from 

 the water immediately around it, and so on until a considerable ac- 

 cumulation would be formed around the foreign substance. 



We can in this way conceive of the manner by which the molecu- 

 lar action, which is insensible at perceptible distances, may produce 

 results which would appear to be the effect of attraction acting at a 

 distance. — From the Proc. of the- American Philosophical Society.
