. Vitamin B-12 in the Great Lakes and its ecological. significance. 
a. Dr. A. D. Hasler, University of Wisconsin. 
b. To determine certain chemical functions of the environment 
and its effects on the population. 
, ce. The waters in the Great Lakes are analyzed for their 
vitamin B-12 content; a number of organisms are subjected to varied proportions 
of this ingredient to determine their life processes as a measure of its 
concentration.
