Excerpt from The Viscosity Coefficient of Air: With an Inquiry Into the Effect of the Roentgen Ray Thereon One of the chief features of the gaseous form of matter is the distinguishing simplicity of its laws. The molecules of the medium in this state seem to act in a less complicated manner than when In a liquid or solid state. The investigation of any property of matter in the form of a gas might therefore be mone simple than a similar investigation on any other form of matter, and the results attending such an effort might serve to throw some light on these other and more complicated forms. The particular phenomenon in question has claimed the attention of investigators for many years and while the general truths may be said to be settled, there have always existed many differences of detail in which one may find a justification for further effort in the same field.
