It was a somewhat critical analysis of experimental methods, and it sounded a caution against premature generalization from laboratory results to the farm. As Dr. Jordan stated, the stations have been and are still putting too much time on mere variables that have no broad significance, and too little time on broad fundamentals. He called attention to...

Σελίδα 65 - From the limited data of ... [the] last two experiments It is suggested that any marked change of temperature predisposes rabbits to this Infection, the severity of which varies with the amount of change, and that a change from low to high temperature has an even more marked effect than that from high to low.
Σελίδα 391 - The book aims to bring together in an orderly arrangement, (1) a store of information which may profitably come within the view of the student who desires to understand the economic phenomena of agriculture, and (2) a considerable number of opinions which have already been expressed as to the meaning of these facts.
