NOTE ON THE DISTRIBUTION OF CRITICAL TEMPERATURES FOR BIOLOGICAL PROCESSES.
The critical temperatures at which irregularities appear in the relations between vital processes and temperature are not distributed at random. As based upon detailed knowledge of individual cases, and as derived from inspection of the frequencies of occurrence, these critical points are usually found to be in the neighborhood of 4.5 degrees , 9 degrees , 15 degrees , 20 degrees , 25 degrees , 27 degrees , 30 degrees .
