It is interesting to notehow small this gland is as compared withthose found in human skin. Figures 2, 3, 4,5, 6 and 7 represent successive stages in 474 Roentgen Ray Treatment of Acne Vulgaris the development of the roentgen ray derma-titis produced. The chief changes noted are a thickeningand desquamation of the horny layer, aflattening out of the sulci and papilli; adefinite thickening of the germinal layer; agradual shrinking of the hair follicleswith loss of the hair shafts; a markedthickening of the collagen bundles of thecorium, and a disappearance of the se-baceous glands at about the time that thehair follicles begin to shrink. At the end ofeight days there are few such glands in theexposed area, and an occasional one may beobserved in the ten-day section, as indicatedby the arrows. In the twelve-day section noglands were found. A careful study of thestructure of the glands found in the eightand ten-day sections showed no definiteevidence of degeneration. This is rather dis-

There can be no doubt that the rays have a destructive action on thesestructures for they are quite plentiful in thesections of normal skin, ancl their absencein the twelve-day sections can hardly becalled a coincidence. It might be assumed that very small dosesof rays have a stimulating effect on theglands since they are supposed to stimulateother structures. In support of this assump-tion, it may be stated that the sebaceousglands shown in Figure 8 are by far thelargest observed in any of the material athand.
