Abstract

The difficulty of manipulating the ordinary apparatus in finding the cohesion of water and other liquids has thrown this beautiful and instructive laboratory experiment out of the reach of most students of Physics. Professor Nichols of Cornell University, says of this experiment: "The difficulties of controlling the conditions are so great, that the determination is one not to be recommended to the beginner." The first difficulty has been to accurately adjust the glass plate used in the experiment so that it will be parallel to the surface of the liquid to be tested; next, on account of the tension applied in separating the portion of the liquid tested the cords stretch, so that it is no longer parallel to the surface of the liquid, and one edge of the disk will come off from the water too soon, thus splitting the particles of the water a little at a time, instead of separating the water area equal to the cross section of the disk all at once.
