    juuctiva and sclerotica adjoining the cornea, and that the consequence of this was relaxation of the muscular walls of the arterioles permitting dilatation of their calibre by disten- sion, owing to the increased afflux of blood directly into it. This view, however, I subsequently renounced as above men- tioned and explained (§ 4). § 70. In conclusion of these'remarks on the vascular con- gestion attending Keratitis, I beg to repeat what I have elsewhere insisted on, that it is a mere excogitation to say that white corpuscles migrate from vessels of the conjunctiva or sclerotica, by boring through their walls, into the interstices of the corneal substance. It is impossible to examine the parts concerned during life. Having, however, displayed a minute section of a detached piece of healthy cornea under a microscope armed with a one-eighth of an inch object-glass, no corpuscles were at first seen on examination; but after a brief interval of time I observed white cells begin to protrude as if from interstices at the edge of the section. Such corneal corpuscles are, no doubt, the objects which Cohnheim appears to have imagined to be colourless corpuscles of the blood which had emigrated from the vessels in the adjacent parts of the conjunctiva and sclerotica, and which, as he supposed, made their way into and through the interstices of the cornea by means of amceboid movements.* 4. Blienomena attending the establishment of vascular conges- tion independently of any lesion of structure. § 71. In my Essay, ‘‘ On the State of the Blood and Blood- Vessels in Inflammation” (‘Guy’s Hospital Eeports ’ for * In my Articles in the ‘ Lancet,’ “ On the alleged Escape of White Cor- puscles from the small Vessels,” I have sufficiently shown the unsatisfactor}'' characters of the observations of Cohnheim, his predecessors, and followers, on the subject. In a reproduction of Lister’s “theory” of inflammation, in a valuable text-book on Surgery, it is stated (to the bewilderment, I fear, rather than the enlightenment of the students) that the said “ theory ” was not received until Colmheim’s discovery of migration in 1867. I do not know if Lister has yet observed the phenomenon which at one time he had failed to see, though not to doubt. Failing his attestation, however, Mr. Victor Horsley describes emigration from a vein in the mesentery of the frog which had been exposed for seven hours]
