The major portion of these losses may be easilycomputed by means of data taken in the test. Thosewhich cannot be mathematically computed are thrownunder the column entitled Stray Losses, and aremade to represent such an amount that the total lossestogether with the useful heat generated in the boilerrepresent the heat from one pound of fuel.

The human mind obeysthe laws of nature,just as did the applewhich fell on the headof Newton. (If the man who is selling the goods could just get itout of his head that the customer is a mystery, and begin tofigure intelligently just how that customers mind works,he would be surprised how easy it is.
