The coldness of water, together with its diminished power of oxygenation, as compared with the atmosphere, is one ...of the direct causes of diminished expenditure in aquatic animals, rendering their life necessarily less intense than that of terrestrial forms, and so longer. In keeping animals in menageries, in rearing pets and domesticated animals, man performs an experi- ment by diminishing personal expenditure. He fre- quently does the same in his own case, leading a careless, labourless existence ; but there is in this as in other experiments (which are rarely so good in physiological enquiry in their results as natural comparisons) a disturbing cause, for Luxury, 'the fertile parent of a whole family of diseases,' as Galen termed her, steps in and works against the diminished expenditure.
