Hehas been unable to discover the smallest appearance of it upon the pillars of theiris, and conceives therefore that it is limited to the cornea. And according tothe same accurate observer, the front of the iris has no true epithelial investment.—Eds.] 358 SPECIAL HISTOLOGY. observed vessels in the cornea of a young Cat (fig. 297), whichI can scarcely regard as anything else than lymphatics. In Fig. this instance, at the margin of the cornea, together with thevery distinct capillary loops containing blood-corpuscles, therewere numerous wider vessels (of OOl—0 02, or even 003),which either extended singly into the cornea to the same dis-tance as the blood-vessels, and terminated in dilated clavateends, or in acuminate points, or two, three, or more together,formed simple loops, from which in like manner other csecalprocesses were given off. Notwithstanding their capacitythese vessels presented a delicate, structureless coat, with scat-tered, appressed nuclei, and contained a clear fluid, in whichfrequently a few, and occasionally even a good many clearspherical cells, exactly like lymph-corpuscles, were visible. IfI had found these vessels in other animals as well, I shouldat once have declared them to be the commencements of thelymphatics of the conjunctiva, but it appears to me, at present,more prudent to regard this explanation perhaps as probable,bu
