    a large number of leucocyles and red-blood corpuscles. Here and there are seen Hocculent mucoid masses, in vvhicli are em- bedded the blood corpuscles, and numerous ova of the bilharzia luematobia. The ova possess brown transparent shells, with a spine placed at the narrow pole of shell. In the ova are seen in some cases living embryos. A distinct head can be made out, in the centre of which is a small aperture surrounded by a circlet of cilia, and leading in some cases into two distinct tubes, in other cases into one tube, terminating in double pyriform mass. The tube is distinctly retractile. Beyond the pyriform mass are seen indistinct granular bodies, whilst between the body wall and shell at its narrow end are sometimes seen granular masses. The embryos are ciliated all over. They are extremely protean in form. In some parts of the field there are seen embryos half in and half out of their shell. In other parts they are lying by the side of the now empty shells. In many cases the embryos are seen to be actively swimming about. They escape either bv a lateral aperture or by longitudinal dehiscence of the shell. The blood and “clots” passed per rectum show exactly similar appearances. The accompanying figures represent (1 and 2) two empty shells, one showing lateral aperture, the other longitudinal dehiscence ; 3 and 4 represent embryos within their shells ; in one the oral aperture is opposite the spine ; in the other it is placed at the broader end of shell; 5 and 6 represent two free embryos, sliow- 1 3 3 4 ing a variety in shape ; 6 is the commonest form met with. The oral aperture is seen to open into a long tube, the oesophagus, which terminates in a double pyriform mass. The rest of the body is
