The article to which I refer contains matter relating to other states of the breast and my description of fibro-adenomas in particular was rather buried among the other material. I am glad to have this opportunity of calling particular attention to the formation of fibro-adenomas only. I do not consider that any types of fibro-adenomas arise from so-called "rests," and it will be seen that I believe that they originate in parts of the gland that have been normal.
Figure 1 shows the two tissues from which the varieties of fibro-adenomas originate. The first tissue (fig. 1 G) I shall
