Excerpt from The Biochemical Journal, 1907, Vol. 1

At first sight it is perhaps not surprising that the various secretions of the body should be credited with a certain quantity of oxygen as well as of nitrogen. These gases are, no doubt, in a condition of simple solution and were they in the proportions in which they occur in serum their presence, on casual consideration, would not be surprising. On further investigation, however, it becomes evident that these very secretions are formed by the passage of fluid through the cells of secreting glands, these cells take up oxygen more rapidly than any other structures in the body are known to do, and therefore it is much more remarkable that such a secretion as saliva should contain as much oxygen as does the scrum, than it would be if the saliva contained none. It is, however, still more remarkable that saliva and milk should be credited with containing more oxygen in solution than there is in the same volume of serum.

The present paper consists of (I) a critical discussion of the analysis of the gases in saliva, which have been obtained by previous workers, and from which it will appear that in the opinion of the author these analyses arc not seriously amiss; (2) a description of some experiments which confirm them; (3) a discussion of the light thrown by the facts cited upon the physiology of certain tissues.
