Histology of the Blood Normal and Pathological Chemically considered ordinary table salt is sodium chloride; that is to say, a compound of the metal sodium and the gas chlorine. Astronomy of To-day A Popular Introduction in Non-Technical Language If the flow is long continued, the patient may be conscious of a persistent salt taste in the mouth, due to the large proportion of sodium chloride which the fluid contains.
