Extract
1. The rate of loss of weight has been determined for eggs from aged hens and from pullets by methods which used both an incubator at 102° F. and a desiccator at room temperature.
2. For both lots of eggs the weight loss per unit area of shell was about three times greater in the incubator than in the desiccator.
3. For the same method the eggs from the aged hens lost one and a half times as much weight per unit area as the eggs from pullets.
