Sattler' objects to the view held by Saemisch, regarding the new-formation of lymph follicles in the conjunctiva, in his so-called follicu- lar conjunctivitis, on the ground that it is without an analogue in pathological anatomy. Nevertheless, we do find examples of the pathological appearance of follicles in places where they never occur in a normal condition (Virchow and Bcetcher=), and analogous in structure to the follicles of the intestine—;, e., in the liver in leuchae- mia; and Birch-Hirschfeld' alludes to the circumstance that the hyperplastic lymphomata are not infrequently complicated with the development, in the connective tis- sue of different organs, as the liver, kidney, etc., of small nodes, corresponding in structure to lymph-gland tissue, and that these secondary lymphomata are seen in variola, scarlatina; leuchasmia, and pseudo-leuchsemia. We see, therefore, a large number of distinguished ob- servers unwilling to agree with one another as to the actual nature of trachoma, and in consequence of this disagreement there can be no certainty in regard to prognosis, and the treatment must be empirical. THE NATURE OF TRACHOMA. The writer's observations are based on the examination of forty-seven cases of trachoma. In every case several of the prominences of the conjunctiva were excised, and in several instances the entire conjunctiva was examined after death. In all cases, at first, the epithelial surface was found smooth, not thickened. The adenoid tissue was infiltrated with lymphoid cells, but the latter were not uniformly dis- tributed, but in places it extended deeper into the tissue and was more closely arranged. At first there is a circum- 'Sattler: Bericht Uber die Heidelberger Ophlhal. Gesellschaft, 1881 p iq Virchow and Boetcher: Virchow's Archiv, Bd. xviii. p 22
