    examined after being plunged in alcoiiol, a perpendicular section exhibits all the successive layers which compose the walls of the intestinal tube. The serous and muscular membranes are sound. The cel- lular tunic is slightly thicker than in the natural state; and under it is placed an opaque, whitish layer, about three milli- metres in thickness, which fdls up the place of the mucous coat, and stands in contact with this latter membrane by its circujn- ference; the villosities are normal, on the mucous surface, while those which correspond to these white layers are conside- rably altered from the healthy state. When this diseased portion is held up to the light, and examined with the naked eye, or with a magnifying power of twenty diameters, two remarkable features are observed : i° The villosities which lie on the surface are hypertrophied, and much longer than usual : they are less transparent than the sound ones which correspond to the healthy parts of the mupous coat. 2° Under these, a series of circular lacunae is observed : their circumference is slightly irregiilar; they are disposed in a line which runs parallel to the surface. These lacunte are produced by the disappearance of the intestinal glands, which have fallen out of their places at the moment when the preparation was made. In fact, in the unequal intervals which separate these lacuucB, a certain number of opaque spots are found; these are precisely the follicles which remained in the intestinal tissue, when the others fell out. In order to ascertain the composition of the tissue which produces this superficial induration of Peyer's patches, a tliin section being made and deposited on a glass slide, is gently struck with the extremity of a camel's hair pencil, in order to separate the tissues and allow them to be viewed apart. The preparation is then coloured with a solution of carmine in ammonia, washed in water, and touched with acetic acid. It then becomes easy to see that the thickened portion of the patches
