    Bidder and Schmidt give the following as the constitution of parotid saliva in the dog:— Organic matter (albumen and globulin) 1-4 Potassic and sodic chlorides 2-1 Calcic carbonate .... 1-2 Water ...... . 995-3 Submaxillary saliva— Organic matter (mucin with traces of albumen) 2 • 89 Potassic and sodic chlorides . . . 4’50 Calcic and magnesic phosphates and carbonates 1‘16 Water 991'45 Traces of sulphocyanate of potassium are also met with in saliva. The saliva undergoes great alteration in certain morbid conditions of the mouth, or of the general system. To take the simplest example first: in stomatitis, tonsili- tis, or pharyngitis, there is a greatly-increased secretion of buccal mucus; as a consequence of this there is greater acid reaction in the mouth, which is made evident not only by litmus, but by the solution, and consequent disappearance at such times, of deposits [of tartar. It is also susceptible of alteration by chronic disorders of the mucous membrane, such as are generally associated with enlarged tonsils, and a granular, flabby-looking appearance of the pharynx (Magitot, loc. cit.'). In the course of many acute diseases the secretion of saliva is greatly affected. In small-pox, salivation, often profuse, is met with ; but, as a rule, the febrile condition is associated with a dry tongue, from the suppression of the secretions of the salivary glands, and with the formation of sordes upon the teeth, due to an excessive outpouring of buccal mucus. The formation of sordes around the teeth is further favoured by the temporary cessation of mastication, so that the mucus can collect and harden undisturbed.
