portion of the cortex. The resulting rapid reduction in the 
relative size of the enormous cortex is much greater than any- 
thing shown in chart 1, and is in the direction of a relative in- 
crease of medullary tissue. This degeneration has never been 
noted except in man. There is nothing resembling it in my 
specimens.

Chart 2 The growth in volume of the male adrenal cortex and medulla. The 
lowest solid line represents the medulla. The broken line marked by crosses 
represents the vakues for the medulla multiplied by ten, so that its growth can 
more conveniently be compared with that of the cortex. 
Charts 2 and 3 show, in solid lines, the growth curve, in volume, 
for the cortex and for the medulla, chart 2 for the males and 
chart 3 for the females. The broken line represents the values 
for the medulla multiplied by ten; so that the relative growths 
of the two parts can be more conveniently compared. The 
values for both the cortex and medulla are expressed in cubic 
millimeters. 
Chart 4 shows the values for the whole of the adrenal in cubic 
millimeters. When compared with the values for the weight of
