Fatty tumors growing in this part of the panniculus adiposus are, for this reason, extremely difficult to enucleate. The papillae are but imperfectly formed, and are for the most part represented by an undulating line; at short intervals are the follicles of the lanugo hairs, which penetrate only the superficial layers of the cutis, the sweep of whose fibres would be otherwise unbroken were it not for the existence of a structure, hitherto undescribed,^ which connects the bases of the hair fol- licle with those parts in which we find the I’oots of the longer hairs imbedded,— the panniculus adiposus. I'his consists of a nearly vertical cleft or slender, columnar-shaped space, extending from the last-named structure in a somewhat oblique direction through the deeper and middle layers of the cutis, and terminating at the base of the follicle which rests upon it. This space is occupied by adipose tissue in its entire length ; hence the term fat column or fat canal ® would seem to be an appropriate name. (Figure 1.) The length of this space is about four mm. ; its width rather ex- ceeds that of the hair follicle above. Its long axis is placed at a slight angle to that of the follicle, which in most cases is nearly perpendicular to the surface, and 1 M.
