Explanation of the Plate. 
PLATE III. 
Fig. 1. The uterus and its appendages as seen from behind. The uterus is laid open 
by a longitudinal incision in order to show the contained menstrual fluid. 
The Fallopian tube is highly congested, and its cavity is raucli distended with 
sanguinolent mucus. The ovary presents several cicatrices on its surface ; 
and at the inner and lower margin it exhibits a purple spot, in the centre 
of which there is a small opening through which the ovule had recently 
escaped. 
{a.) The spot at which the ovule was found. 
Fig. 2. The left ovary laid open in a line through the centre of the purple spot, 
showing the cavity from which the ovule had escaped, surrounded by a 
clot of dark blood, most of which was effused into the substance of the 
Graafian follicle. 
Fig. 3. A portion of the sanguinolent matter taken from the uterus, and magnified 
about 200 times. It was found to consist of blood-discs, most of which 
were beaded at the edges {a a) ; of ciliated and cylindrical epithelium {h h) ; 
of granular corpuscles, some of which were oval and others round (c c ) ; of 
spindle-shaped bodies {dd) ; of numerous minute granules ; and of a thick 
gelatinous fluid which bound all the elements together. 
Fig. 4. Fluid from the Fallopian tube, treated in like manner: it consisted of nearly 
the same elements. The fluid in which the corpuscles floated was, however, 
of a serous, not a gelatinous character. 
N.B. To prevent obscurity, only a few of each of the elements have been 
figured. 
Fig. 5. A portion of the ovule mass taken from the left Fallopian tube, and magnified 
200 times. The entire mass consisted of nucleated cells {membrana granu- 
losa) arranged in an irregular manner. Interspersed through the cells 
were many oil-globules, probably the broken-down yelk. 
Fig. 6. A part of the middle of the mass, magnified still more, showing the arrange- 
ment of the cells and the position of the oil-globules. 
Fig. 7- The right ovary removed from the uterus and placed vertically. 
(a.) The external surface showing several stellate cicatrices ; and at its
