The lowest oxygen content was S.69 cc. per liter, station R (see also table 

 2) and the highest was 7.54 cc. per liter, station L. The pH of the sur- 

 face water in these observations does not parallel the oxygen content when 

 the stations are distantly located (see map, page 372). But on the other 

 hand ^vhen the stations are more closely located there is more agreement 

 between the variation of the pH and the oxygen content of the water, i. e., 

 a higher oxygen content is found where there is a high pH. There is an
