DATA FROM OTHER CASES

of the cervix. The patient was a married woman, Vpara, and her periods' 
latterly had been somewhat irregular. The last extended from 14th to 
19th August, 1887. On 20th August coitus occurred for the last time, 
and the operation was performed on the 29th August. Leopold regarded 
the ovum as of the 8th day on account of the history, but it is clearly 
much older. It is possible that the supposed menstruation was a haemor¬ 
rhage due to the presence of the tumour, but it is also possible that it 
represented menstruation occurring during pregnancy. The embryo in this 
case was not recognised, but from the size of the blastocyst and the 
state of the villi, the age may be reckoned as about the same as that 
of ovum “v. H.” of v. Spee, namely, 17 to 18 days. 
VII.—Ovum of Reichert. 
This ovum, the histological details of which are not very exactly 
known owing to the date (1873) at which it was described, measures 
internally 5‘5 x 3'3 mm. It was obtained at a sectio upon the body of a 
young married woman who had not previously been pregnant. Her 
husband left Berlin “in the first days of November,” and on 7th November 
the expected menstruation did not appear. During the night of 21st to 
22nd November she died suddenly, her husband still being absent. 
Reckoning from the date of the missed period, and allowing an addi¬ 
tional three days for the arrest of the menstrual process, the age of this 
ovum would be 17 days. The dimensions being very similar to those 
of the two preceding ova, it should probably be regarded as from 17 to 
18 days. 
VIII.—Ovum of Rossi Doria. 
The ovum measures internally 6x5 mm., and the decidual chamber 
9x8 mm. The patient was 30 years of age, had been 8 years married, 
and had 5 children. The last menstruation began on 30th January, and 
lasted between 3 and 4 days, as was usual. On the 23rd February, 
after dancing at a ball, she observed a few drops of blood, which she 
regarded as the return of menstruation almost a week too soon. This 
increased during 2 days into definite haemorrhage, and there were slight
