The method adopted was to take the frequencies in groups of three, add them together, and obtain the mean. For instance, the number of occur- rences of one, two, and three corpora lutea were added together and divided by three. Then the numbers for two, three, and four; three, four, and five, were treated in the O ACTUAL FREQUENCIES 1934-35 1935 -3G. 5 10 15 20 25 30 35. 5 10 15 20 25 30 NUMBER OF CORPORA LUTEA Fig. 9.

Each frequency comes into the calculations thrice and a consider- able smoothing effect is obtained, which eliminates the fluctuations due to faulty sampling and possible individual variations while preserving the real trend of the fre- quencies. Only those ovaries with one or more corpora lutea have been included, since this part of the discussion is confined to definitely mature 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 Institute of Oceanographic Sciences (Great Britain); National Institute of Oceanography of Great Britain; Great Britain.
