Polarograms of two different hind-gut samples from Cryptocercus: (A) aged 5 hours in the electrolysis vessel and in contact with the mercury pool, pH , and (B) aged 4% hours in a vessel without mercury contact until transfer to the electrolysis vessel, pH (sensitivity X 5). crease, and the shift in -E y2 to a more positive reduction potential correlates with pH drop. Evidence for this conclusion rests on : 1. A fluid sample aged between four and five hours in a mercury-free container, after removal from the roach and deposit inside the electrolysis vessel, registers a wave (Curve B, Fig. 6) coresponding closely with a fluid sample aged the same period in solution chamber contact with mercury (Curve A, Fig. 6). 2. According to Benesch and Benesch (1952), more energy is required for mercaptide complex reduction than for the free compound that gave rise to the complex. Therefore, the resulting reduction wave would register at a more nega- tive E y% for the mercaptide—not more positive as recorded in this study—to reflect the low dissociation of the Hg-S bond. 3. Also in the event of mercaptide formation, two separate waves would be expected to appear polarographically. The difference between the --E i/> of the gradually forming mercaptide and the more negative E !/o of disappearing GSH would likely be great enough to initiate two separate reduction waves separated by a shifting plateau. DISCUSSION The appreciable presence of atmospheric oxygen coupled with diverse, unique, and efficient animal systems that transport oxygen suggest unspecified claims of anaerobiosis (as to degree) should be questioned.
