search for an equation n 1 =f (t), which would sum up the values n, brought out by the 
gas analyses, curve B is one approximation, and curve C another to this function. Either 
curve is given for what it is worth. My interpretation of the diagram is that, while 
at low temperatures (up to about 15°) the processes of oxidation which go on in the 
water are too slow to interfere materially with the establishment of absorptiometric 
equilibrium, they do so more and more markedly at higher temperatures. Assuming the 
curve BB, in a rough sense at least, to represent the average state of matters, I have 
selected a number of exceptionally high and low values found for the amount of absorbed 
oxygen, and traced the samples to their place of collection, as shown in Table XVIL 
Table XVII.

The four high values for n u as we see, all belong to places in the Pacific, far away 
from the land. This is all that I am able to see.
