Experiments performed at Iowa Lakeside Laboratory during the past summer indicate that both forms show fluctuations of from 3 to 6 degrees F. in the so-called non-critical ranges of their environment (50-80 degrees F.). When subjected to a rapid environmental drop the rectal readings show a somewhat greater lag than when cooled more slowly. In both procedures a check in drop is noted at about 40 degrees F. (4.5 degrees C.) and there is maintained for a considerable interval of time.
