Abstract
After I had put myself the task of investigating the correctness of the results obtained by Heibges concerning the clausulae of Chariton, I decided to determine the frequency in which the different rhythmical forms appear in the authors of non-rhythmical works. For that purpose I investigated the prose works of Thucydides and Plutarch as carefully and in as specified a form as was possible. This I did with the intention to compare the percentages with those of Heibges. In this comparison, however, I came to the conclusion that the figures for Thucydides and Plutarch differed considerably, and that in such a way that certain conclusions could be drawn concerning the manner in which Plutarch constructed his clausulae according to fixed rules
