In experiment No. 2 the temperature did not at first rise so rapidly as in the others, but it shot up rapidly after a time, and reached 250° in about 1¾ hours. In this experiment, the wool was teased out with perhaps overextreme care; in the last two experiments less care was taken.

Similarly, there is no occasion to permit at this critical time any loss of production through overextreme cautiousness in the interpretation of specifications in those cases where for good practical reasons specifications must allow for some exercise of judgment, due caution, and care on the part of inspectors.
