ifications of his work to another gauge maker on the other 
side of the continent, that gauge maker could turn out 
an exactly similar piece of work. Moreover, he could 
prove, by means of his instruments, that the work was 
identical. The chemist does not make up his compounds 
after a cook-book formula, so many cups of this and so 
many spoonfuls of that. He weighs his materials on the 
finest of scales which tell him to a thousandth of a gram 
what amount he has. The cook-book method is the em 
pirical or home remedies method and many excellent re 
sults this method has produced; but no two cooks can ob 
tain the same result from the same recipe. The scientist 
can, because his method is standardized and minute, and 
enables him to speak in terms that always mean the same 
thing. This statement holds true in any field of facts 
to which the scientific method has been applied. Another 
excellent example is the weather report. The weather 
man is still the subject of frequent jibes. It is a common 
practice to look at the weather report and then believe 
the contrary. But how many people are willing to have 
the weather man replaced by the good old-fashioned goose- 
bone prophet? And how many would stake their own 
empirical judgment against the scientific inductions of 
the weather man? Meteorology is the result of applying 
the scientific method to the study of atmospheric condi 
tions, that is, substituting for the crude and unaided 
human faculties such scientific tests as thermometers, 
barometers, rain-fall gauges, and other quantitative tests. 
Consequently, weather men all over the country, in making 
up their weather reports, can describe atmospheric condi 
tions to each other in standard and unambiguous terms. 
There is no Yankee or southern dialect in the science of 
meteorology.
