CHAPTER XL. THE SALIVA AND NASAL SALIVA. The saliva is derived from the parotid, submaxillary, and sublingualglands, and from the mucous glands within the mouth. The mouth shouldbe washed with a warm alkaline solution and afterward with cold water,in order that the saliva obtained may be perfectly pure for the washing the glands may be stimulated by the application ofdilute acid on a glass rod. The normal amount secreted in twenty-fourhours varies from 1 to 2 pints. It is colorless or of a light-bluish color,and somewhat stringy. On standing in a conical glass two layers form,the upper clear, the lower cloudy. The reaction of saliva is alkaline. Microscopical Examination. The following formed elements areobserved: 1. Salivary corpuscles of the appearance of, but larger andmore granular than, a white corpuscle. 2. Epithelium. The squamous. Buccal secretion.

The cells are large in size andof polygonal shape. 3. Fungi. In health the mould and yeast fungiare seldom found. In disease they are present in large numbers ; fission-fungi are met with in great numbers, both in health and in disease. Inhealth small and large colonies of micrococci are found along with abun-dant bacilli. Miller has studied the micro-organisms of the mouth care-fully and exhaustively 1 both by microscopical examination and culture-methods. The following are found to be pathogenic: (1) Leptothrix1 See Dental Cosmos. 585 586
