Fig\ 13. Another form of epithelium-cells — formed of blood-corpuscles (?) — found 
with those in the preceding- figure. Colour yellowish, except the con- 
tained pellucid objects. Their long- axes parallel.

Fig-. 14. Blood-corpuscles — now cells — arranging- themselves to form muscle. 
Found with an ovum of ten hours, taken from the Fallopian tube (par. 
34.). 
Fig. 15. A portion of the same, more highly magnified. The pellucid objects con- 
tained in the blood-corpuscles (now cells) in many instances were seen 
to be situated — not in the centre but — on one side. When viewed singly, 
these objects appeared yellowish ; in a mass, blood-red (pars. 34. 37.) . 
Fig. 16. Blood-corpuscles — now cells — arranging themselves to form muscle. 
Some of them remarkably elongated (pars. 34. 38.). Found in the Fal- 
lopian tube of a Rabbit killed eleven hours post coitum. 
Fig. 17. Blood-corpuscles (a, y, &), and portions of muscle ((3/3, yy) formed of blood- 
corpuscles, found with the objects figs. 14 and 15. This figure presents 
several transition states between the unchanged blood-disc a, and the 
necklace-like arrangement of cells (3(3 . In the latter, the contained pel- 
lucid object had a central situation, but the cells had scarcely coalesced. 
yy Presents a more advanced state. Here the cells had more or less 
coalesced into a cylinder, and the contained pellucid objects together 
formed, or seemed about to form, the medullary portion of the cylinder. 
In this figure are also objects resembling fig. 15. (pars. 32 to 35. 3 7. 38.)

Fig. 19. Outline of capillaries as seen in a portion of the infundibulum of the Fal- 
lopian tube, taken from its inner surface, in a Rabbit killed 5| hours 
post coitum. These vessels were filled with blood-corpuscles in the 
state represented in fig. 20. At the lower part of this figure (fig. 19.) 
are epithelium-cells carrying cilia. These epithelium-cells are arranged 
parallel to one another, and perpendicular to the general direction of the 
capillary vessels. The small extremity of the epithelium-cells is directed 
towards the capillaries. Whence their frill-like appearance (in the figure), 
and the great extent of their ciliary surface. External diameter of the 
largest vessel 100 diam. (par. 46.) 
Fig. 20. A portion of the capillary vessels in the preceding figure, more highly mag- 
nified (300 diameters ), to show the appearance of the blood-corpuscles 
with which they were filled. The blood-corpuscles presented in their
