glands, and form in their substance reticulations strikingly like those formed previously in the walls of the intestine around the solid substance of the Peyerian follicle—suggesting thus to the naked eye the similarity, and by consequence the homology, which a microscopic examination enables us to prove to exist between the lymph sinuses and the solid masses they surround in the Peyerian follicles and in the mesenteric glands respectively [1].
It is the demonstration of the relation of the lymphatic or lacteal vessels, or sinuses, as the case may be, in different animals, to the solid ampulla-like masses in the Peyerian
- ↑ I take this opportunity of expressing my surprise that Henle has not seen his way towards accepting this view of the real nature or Bedeutung of the Peyerian follicles. In his 'Gefasslehre' of 1868 (p. 404) he refers us back to his 'Eingeweidelehre,' p. 57, of 1862, where, as also in the second edition, 1873, p. 62, the absorbent character of these structures is denied, just as it was by Hyrtl in his 'Handbuch der Topographischen Anatomie,' 1860, p. 646, and by Teichman, 'Das Saugadersystem,' 1861, pp. 86-91. The view which I have adopted was accepted by a distinguished Fellow of this College, Dr. Burdon-Sanderson, in the Eleventh Report of the Medical Officer of the Privy Council for 1868, p. 96.
