It is a clear or somewhat milky-looking, semiliquidmaterial, in which numerous epithelial lamina?, which have beenthrown off during the normal process of desquamation, may befound. It has been stated that the reaction of the vaginal secretionin virgins is invariably acid, while an alkaline reaction is the rule inthe tUflorees. During pregnancy, however, the secretion is probablyalways acid. In five hundred cases which Kronig examined in thisdirection an alkaline reaction was never observed. According toZweifel, the vaginal secretion contains traces of Microscopically, numerous epithelial cells, mucous corpuscles, afew large mononuclear leucocytes cellular detritus, and bacteria arefound (Fig. 132). Doderlein2 has described a non-pathogenic Fig. Vaginal Mucous corpuscles; b, Vaginal epithelium ; c, Epithelium from vulva. bacillus or a group of bacilli which are characterized by the factthat they give rise to marked acid fermentation of sugar, and heregards these organisms as the only ones which are constantlypresent in the normal vagina. Kronig and Menge, however, state 1 Zweifel, Arch. f. Ovnaek., 1881, vol. xviii. p. 359. 2 Doderlein, Ibid., 1887, vol. xxxi. p. 412. 569 570 VAGINAL DISCHARGES. that they are often absent. These observers have found, on theother hand, that under normal conditions there are various bacilliand cocci present which belong to the class of obligatory anaerobes,and are likewise non-pathogenic. Unfortunately they have notdescribed these organisms in detail. Xear the outlet they foundbacteria which may be cultivated upon alkaline aerobic eulture-media. bu
