    lowing lesions: ''The sections were triangular, and contained part of the conjunctiva from the upper retrotarsal fold. The con- nective tissue was particularly well developed between the con- junctiva and the gland, and penetrated in robust bundles to some distance among the lobules of the gland. Round cells were scattered throughout the connective tissue, and beneath the. epithelium of the conjunctiva there was a continuous layer of closely packed round cells. ' Streets ' of round cells could be traced along the fine ramifications of the connective tissue among the lobules. The granulation of the protoplasm of the gland cells was very conspicuous, and the cells' were so closely crowded that it was impossible to make out the lumen of a single acinus. The epithelium of the ducts was distinctly swollen; the ducts them- selves were surrounded by a dense round-celled infiltration which, around the largest ones, is arranged in the form of small round islands. The bloodvessels were dilated and engorged. The con- nective tissue underneath the conjunctiva contained colonie's of micrococci which occupied the lymph spaces. The condition of the lachrymal gland in chronic epiphora has been the subject of an interesting research by G. Stanculeanu and A. Theohari.''' These investigators examined sections of the palpebral lachrymal gland from (i) cases of epiphora with in- tact lachrymal passages; (2) cases of epiphora where the lachrymal passage had been made permeable by the passage of sounds; (3) a case of epiphora with impermeable lachrymal passages; (4) a case of epiphora from congenital dacryocystitis. The lesions found consisted of an interstitial inflammation and certain modi- fications in the cells of the acini. The latter were in a state of de- generation, the protoplasm being converted into a delicate net- like formation containing brightly staining granulations. In the lachrymal glands of dogs stinuilated to excessive action by pilo- carpine they also found a punctuated protoplasmic reticulum, /. (?., at the intersection of the lines forming the net-like figure there was a fuchsinophile granulation.
