Hemorrhages had also taken placealong the roots of the oculo-motorius, and also at the sulcus oculo-motorius ; also along the intra-pontile course of the abducens and thetrigeminus. ? The roots of the other nerves presented nothingabnormal. A large hemorrhage had also taken place at the trigonum inter-pedancular, surrounding the roots of the oculo-motorius. Thishemorrhage, which had taken considerable proportions, was not,however, sufficient to call forth symptoms of apoplexia sanguinea—resp. death. The examination showed no traces of thrombi or Fig. 3 shows part of the intra-pontile fibers of the abducensnerve, some having been pushed aside, and some destroyed, by thehemorrhages along its course. The summary of this examination shows: 1. Normal nuclei of cranial nerves. 2. Degeneration in part of the oculo-motorious nerve. 3. Hyperemia, diapedesis of the blood corpuscles, and hemor-rhages of various proportions. SOCIETY REPORTS. 321 The results obtained agree, in general, with those, of Mendel, pub-lished in the Neurologische Centralblatt, 1885, No. 6. To the pathological anatomy of diphtheritic paralyses nothing hasbeen added since the publication of Mendels case. A compilationof previous observations on this subject is to be found in VirchowsArchiv filr Pathologische Anatomie. vol. lxxxv., p. 214, by PaulMeyer. In conclusion, I tender to Prof. Mendel my hearty thanks forthe kindnesses shown me in the preparation of this paper, as well asfor materials used. 5 Rue Rollin, Paris. Jwckty Im
