AB A statistical analysis was made of the influence of various factors on the duration of hypnosis in the albino mouse. Over a period of about a year and a half, broad chronological subgroupings were found, lasting for months at a time, in which sleeping-times of similar length were observed. No significant diurnal variations were encountered. The length of sleeping-time was found to increase, in approximately linear fashion, with increased barometric pressure. Shorter sleeping-times were experienced with higher wet-bulb or dry-bulb temperatures. When the duration of hypnosis was less than about one hundred and ten minutes, shorter sleeping-times were associated with higher relative humidity values. The existence of an association or relationship as determined above, does not imply cause and effect.
