In the present investigation the author made an attempt to make clear the presence of GG-dipeptidase activating inorganic ions such as Co++, Mn++ and Mg++ in the pyloric caeca of several fishes, tunny, bonito, and yellow-tail as well as in their glycerine extractives.
As shown in Tables 2, 3 and 4, whereas Co++ and Mn++ were not detected, the presence of Mg++ was verified, its amount being calculated as 30-50mg % for fresh pyloric caeca. It seems that about 70% of the Mg++ is transferred to the glycerine extractives.
