The chorionic vesicle, the embryo of which forms the subject-matter of this paper, was presented to one of us (HILL) by Dr. ROY DOBBIN, of Cairo, through the kind offices of Professor D. E. DERBY. In appreciation of his valuable gift, We have much pleasure in associating Dr. DOBBIN’s name with the embryo. The clinical history supplied by Dr. DOBBIN is as follows: “ Coitus, 6.10.23 ; effort probably causing abortion, 21.10.23; first bleeding, 22.10.23; abortion (painless), 23.10.23." Although an abortion, we see no reason to regard the specimen as other than perfectly normal.


The chorionic vesicle (which was preserved in spirit) was, when received, somewhat flattened and shrunken (fig. 1, Plate 29). Except over a small area on one side (approximately 3 x 2 mm in diameter), which was almost bare, the vesicle possessed a fairly uniform covering of short, close~set, branched villi (fig. 2, Plate 29), to which at one point a small fragment of blood—clot adhered. Including the villi, its dimensions in alcohol were as follows : 11.5 mm (in long diameter) x 8.5 mm (in short diameter) x 45 mm (in thickness). After clearing in oil of cedar-wood, the corresponding internal diameters were 9 mm x 5.5 mm x 2.5 mm. The vesicle, after being photographed and drawn, was dehydrated and cleared in oil of cedar-wood. A small portion of the chorion, including the bare area, was then carefully removed, and through the opening so made it was possible, fortunately enough, to locate the embryo under the binocular dissecting microscope. The embryo was then isolated along with the segment of the chorion to which it was attached, and stereo-photographs were successfully taken of it, in the cleared condition in oil of cedar—wood.
