✦ Synopsis

This is a very old subject, having been worked upon by many eminent chemists on both sides of the Atlantic, and from many different views.

Some have devoted their ideas to the prevention of scale formation inside the boiler, under which heading you will find in literature and on the market at the present time as many remedies as there are patent medicines for the ailments of the human body.

Others have taken up the purification of water outside the boiler ; while again others have debated as to the chemical salts existingin these deposits. With this latter subject I wish to deal this evening, in conjunction with a study of their physical appearance.

Before proceeding with these deposits, I wish to call attention to the vast amount that accumulates in a boiler from a good water for steam purposes in a month's run.

An average of several analyses of a water which islargely used in Philadelphia, the Schuylkill, is as follows (when it is elear) : Grains Per U.S. Gallon.
