properly cooled, and critically observed for several hours. Indeed 
they were kept in the boiled water for more than twenty-four hours, 
the flask all the while being closely stoppered with a rubber cork 
as before. A very few of numerous records are given in Table 
MIT 
TABLE VIL 
In this table are given the reactions of two specimens, A and B, which had been placed in the deoxygenated 
water. As will be seen there is little or nothing distinctive in any way. Attention may be directed 
to the rather marked recovery time shown in A at the seventh and fifteenth test, and in B at the first. 
It was thought at first that A was likely to show the periodicity mentioned by Yerkes, hence the tests 
were carried on till thts was clearly disproved, the same being evident in the reactions of B.

Similar records of the same specimens were made in the usual 
aquarium water, or that obtained fresh from the harbor. But 
there is little to indicate any effect due to inadequate oxygen supply. 
After continuing in the boiled water for as much as forty-eight 
hours not the slightest indication of physical discomfort, or modi- 
fication of behavior, could be detected.
