1904-5.] ON THE ABSORPTION OF FAT IN THE INTESTINE. 259 
EXPLANATION OF PLATES. 
In the various Figures ad, signifies adenoid tissue; 6, blood capillary; c, a poly- 
morphonuclear leucocyte; f and im, columns and masses of fat between epithelial cells; 
jd, fat in lumen of lacteal; fl, fine streams of fat traversing wall of lacteal; fs, network 
of fine lines of fat in wall of lacteal; ec, large lymphoid cells. 
FIGURES 1—12 and 14.—From villi of guinea-pigs fed with yolk and dialysed iron. 
Flemming’s Fluid, Hematoxylin and Eosin. 
FiGuRES 3 and 8 are tangential sections of the epithelial cells of the villi. 
FiGure 13.—From villus of guinea-pig fed with yolk. Formalin ten per cent., 
four and a half days, Scarlet Red. Showing beadlets of fat in the striated border. 
FIGURE 15.—From villus of guinea-pig fed with yolk, showing contents of 
central lacteal with some fat droplets. 
FiGuRE 16.—Intestinal epithelial cells of frog fed with olive oil, isolated, showing 
fat particles in striated border. Scarlet Red. 
FicurE 17.—Isolated epithelial cells of intestine of starving Necturus, showing 
droplets of fat in cytoplasm, but none in striated border. Formalin, Scarlet Red. 
FiGurE 18.—Isolated epithelial cells of the intestine of a Necturus fed with olive 
oil, showing the distribution of fat in the striated border and in the cytoplasm. For- 
malin, Scarlet Red. 
FiGurE 19. Epithelium, isolated, from duodenal villi of rabbit fed on olive oil, 
showing beadlets of fat in the striated border and in the cytoplasm. Formalin, Scarlet 
~ Red. 
FiGuRE 20.—Isolated epithelial cells from the intestinal villi of a dog fed on olive 
oil, showing fat in the striated border as villus in the cytoplasm. Chloral hydrate, 
Scarlet Red. 
FiGurE 21.—Isolated epithelial cells of the intestinal villi of a rabbit fed on olive 
oil and killed three and a half hours afterward. Osmic acid for twenty-four hours.
