- 1. A partially protein deficient diet caused a very marked suppression of the X zone of the mouse adrenal.
- 2. A 77% casein diet resulted in appreciable reduction of the X zone, indicating that the X zone is maximally developed at moderate levels of dietary protein.
- 3. Replacement of a part of the carbohydrate by a mixed fat was without any marked effect on the X zone.
- 4. The X zone was larger on a synthetic diet than on chow.
