			* The microscopic pattern of the endometrium during the last 14 days (postovulatory or progestational phase) of any menstrual cycle follows a regular identiﬁable histologic sequence of events. The "dating" for each of these postovulatory days conirms to what is termed a “standard cycle" with ovulation on day 14 and menstruation on day 28.
			* Coital date reported from memory, accuracy questionable?
			* This ovum was ﬁxed in acetone for histochemistry (see MSS. page 448) and has not been given an accession number at the Carnegie Laboratory. Because of the different ﬁxation technique, its measurements are not included in table 3.
			* In a few instances where the catamenial history was insufficient, the range in onset of catamenia was widened arbitrarily afford a longer potential ovulation time.
			* "Periods are 28 days apart." Obviously this patient ovulated somewhat earlier than the EOT of 13-17 in order to have roduced a 17-day ovum on day 28 of the cycle. Therefore she must have ovulated about day 11.

1 Probable day of ovulation is at best an estimate based upon (a) the apparent developmental age of ovum, (b) the

terpretation of the degree of progestational change of the endoznetrium and ((5) the clinical history.

'-' Of the Coiﬁal dates recorded by the patient the One giVen is most likely to have resulted in the pregnancy here descril;

A well isolated or single, and therefore, critical coital date.
7‘ Estimated ovulation time is based on the fact that the modal time of ovulation is 14 i 2 days before the next expec period, as follows:

25-27, range in onset of catamenia. 16-7172, range in ovulation 9-15, E.O.T. in this patient Normal fertilizer? ova of 2-17 days of development

‘The microscopic pattern of the endometrium during the last 14 days (potovulatory or progestational phase) of any men.rual cycle follows a regular identiﬁable histologic sequence of events. The "dating" for each of these postovulatory days conirms to what is termed a “standard cycle" with ovulation on day 14 and menstruation on day 28.

5 Coital date reported from memory, accuracy questionable? °Thi ovum was ﬁxed in acetone for histochemistry (see MSS. page 448) and has not been given an accession number at Le Carnegie Laboratory. Because of the different ﬁxation technique, its measurements are not included in table 3.

7 In a few instances where the catamenial history was insufficient, the range in onset of catamenia was widened arbitrarily

» afford a longer potential ovulation time. , 3 “Periods are 28 days apart." Obviously this patient ovulated somewhat earlier than the E01‘ of 13-17 l!l order to have

reduced a 17-day ovum on day 28 of the cycle. Therefore she must have ovulated about day 11.
