the quantity is hardly up to the average, and the same is seen in 
ulceration of the stomach. In those cases associated with diarrhoea 
or ascites the secretion is often far below the normal. 
Pulmonary Diseases . — In bronchitis and in the early stages of 
pneumonia the secretion of saliva is generally up to the full 
average, and may even exceed it. In chronic phthisis the secre- 
tion of saliva is always very scanty. 
Cardiac Diseases . — The salivary secretion is almost constantly- 
diminished when the heart affection is of a grave character. 
Nervous Diseases . — In affections of the cord, the quantity of 
saliva secreted reaches, and even surpasses, the average amount. 
In the case of cerebral tumours the reverse is found, however. 
Renal Diseases . — In chronic Bright’s disease, the secretion i& 
generally scanty. 
In simple anaemia, in the chronic forms of rheumatism and 
in Addison’s disease, the amount of saliva secreted is subnormal. 
In fevers generally, when the temperature is at all high, the 
secretion is lessened in amount, though the amylolytic power is 
increased. 
In many cases where the secretion is scanty the diastatic power 
is likewise feeble, and, on the contrary, where the secretion is 
copious its proteolytic power is also great.
