O-2 grMir."1.) Of course, the first estimate with body temperature below ambient temperature was high because of the heat flow into the animal, and the latter three were low for the reverse reason. An average maximum between these is equivalent to 9 cc. g.~1hr.~1. This is a sub- stantial but not unreasonable rate for such a small animal. But when it is recalled that the body temperature was only 15-25°, it is much more striking. Even with.
