In the lower egg, the first area of membrane wrinkling is visible at approximately one o'clock on the egg periphery; the elevation of the entire mem- brane is still at about the normal height. In the upper egg, the second area of membrane "blistering" has begun to appear, the original area of crenation still being visible at the lower pole of the egg. FIGURE 2. Another pair of eggs, cold-treated for 150 minutes with temperature shock and photographed 21 minutes after the end of treatment.
