Mr. C. E. Stromeyer, M.Inst.C.E., M.Inst.M.E., shewed 

 that the water hammers which result if a straight tube containing 

 water and its vapour be subjected to vertical jerks occur near 

 the surface if the tube has been standing for some time, and 

 near the bottom if the water has been agitated. He also pointed 

 out that it is rather difficult to explain why a water column 

 ruptures under weak forces, for the surface tension of an 

 infinitely small vacuum bubble is very great. 



Professor W. W. Haldane Gee, B.Sc, M.Sc.Tech., showed 

 some experiments with Bunsen and Luminous Flames.
