 method of exhibiting the sympathy of pendulums. Magnets suspended horizontally 

 end on to one another in the same straight line. " Interesting illustration of the 

 linear propagation of dislurbances in a medium consisting of discrete massive particles 

 when only contiguous ones act on each other... It might be curious to enquire 

 whether a certain form of the equation of motion might not give some hints as to the 

 formation of a dynamical hypothesis of the action of transparent solids on the lumini- 

 ferous ether."
