Excerpt from Biennial Retrospect of Medicine, Surgery: And Their Allied Sciences, for 1865-6 When a solution of nitrate of silver is injected into the lymphatics the parietes of the smaller vessels are found to present certain wavy [dark lines. Two explanations have been given of the cause of this appearance; V. Recklinghausen refers it to the staining of the tissues intervening between the epithelial cells and connecting them together; whilst Auer bach (researches on Lymph and Blood-vessels, 'virchow's Archiv, ' Bd. 33, p. 340) thinks it due to the combination of the silver salt with thread-like masses of albuminous and saline materials lying in fissures of the vessels. The lines vary in breadth, and this appears referable, in part at least, to the strength of the silver solution. S. Basch ('wiener Bd. Who has paid particular attention to the commencement of the lacteals in the villi, regards these vessels, in opposition to Teichmann and others, as only large and regular-formed spaces, possessing neither a proper wall nor an epithelial lining, the illusory appearance of the latter being due to the presence of lymph corpuscle-hke bodies, belonging to and forming part of the proper connective tissue of the villus.
