$tional centre for the levator palpebr^e- superioris exists in the Fig. 27. human brain, I think it must be, sought for in the region now under consideration ([12] fig. 27.) ''Grasset, Eendu, &c.) of isolated paralysis of the levator palpebrse superioris as- sociated with cortical lesions situated ' pour la plupart' towards the posterior part of the parietal lobe. It would appear further that the lesions occur in the pli courbe when ptosis alone manifests itself, and in the lobule of the pli courbe when the ptosis is associated with paralysis of the face and limbs (p. 14). But in opposition to these conclusions we have cases on record of lesion of the pli courbe and its lobule without any such results. Charcot and Pitres {Revue Mensuclle, ^-c. 1877, p. 456) have reported a case of the kind, and Samt {Archiv fur Psychiatric, 1874, p. 209) has reported another, in which the angular gyrus and supramarginal lobuleVere the seat of lesion on both sides, likewise without paralysis. Several other similar cases are on record; Gallopain {Bull. Soc. Anat. Siance, November 23, 1877) relates a case of an epileptic in whom the pli courbe and supramarginal gyrus were deficient on the right side without ocular symptoms; and Chavanis {Gomptes Reiidus de la Soo. des Sciences Med. da Lyon, 1877) gives a case of old haemorrhage into the lobule of the pli courbe, in which, though there was hemi- plegia of the opposite side, no ocular symptoms wore observable. It is obvious, therefore, that as ptosis does not necessarily accompany lesion$
