In both the last two cases, the deflections were (as they 

 should have been) opposite to the preceding ones. 



Series 4. — The disks were drawn so far back in the side- 

 tubes that the distance from the inner surface of the glass tube 

 amounted to 8 millims. They were thereby less exposed to 

 the mechanical action of the stream of water.
