The distribution graphs illustrate the inhomogeneity of the population of sea urchins throughout an annual cycle, not only in gonad index but in content of various organic constituents in the gonads (last four graphs). Glycogen content of gonads shows greatest variability, non-protein nitrogen (NPN), least. For explanation see text. with a normal distribution, not to a skewed one such as is the population dealt with here. The over-all averages for the entire year disclose some interesting information about the gona

For explanation see text. with a normal distribution, not to a skewed one such as is the population dealt with here. The over-all averages for the entire year disclose some interesting information about the gonads (last line, Table I). The ovary is distinctly richer than the testis in lipid and glycogen but the testis appears to be richer than the ovary in non- protein nitrogen, protein nitrogen and possibly in salts (ash) and water, although the few samples taken and their variability from month to month make any deduc- tions on the latter two substances Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
