show its internal structure. It has no head, its trunk is 

 very much curved, and possesses four misshapen limbs. It 

 was connected with the cyst by a large funnel-shaped 

 umbilical cord, which contains a coil of intestine. 



Mr. Young states that " when the foetus was taken from the 

 cyst it was covered with sebaceous matter, and when this was re- 

 moved, it appeared as rosy and healthy as if it were alive." At 

 the upper extremity of the trunk a fibrous mass is seen with a 

 portion of the cyst adherent to it ; this is said by Mr. Young to 

 have been " of a dark-red colour when first taken from the cyst, 

 and abundantly supplied with blood." It is exactly similar to the 

 mass usually representing the brain in anencephalous foetuses. That 

 part of the foetus which, corresponds to the frontal region bears a 

 narrow line of fine hair upon it ; this forms a long lock on either 

 side. The vertebral column consists of eleven blocks of bone, re- 

 presenting as many vertebral centres. The posterior aspect of 

 these is covered by a membrane ; there are no remains of the 

 spinal cord, and no traces of laminse. The skin on either side of 

 the vertebrae is covered with short fine black hairs. The sacrum 

 is rudimentary, and entirely formed of cartilage. One of the ver- 

 tebral bodies in the dorsal region seems also to be entirely formed 

 of cartilage. The vertebral column is surmounted by several masses 

 of bone and cartilage, which probably represent the base of the 

 skull and facial bones. The axis is doubled almost at right angles 

 in the dorsal and lumbar regions. A small opening, in which a 

 bristle is inserted, is seen in the mesial line at the most anterior 

 part of the foetus ; it is apparently a vessel, probably a median 

 carotid. 



In front of the hair, at the anterior part of the foetus, is a frontal 

 proboscis, considerably enlarged and perforated at its free extre- 

 mity : it is extremely similar to the same structure in cases of 

 cranial arrest. (See Nos. 162 et seq.) 



The body-cavity is not divided by any diaphragm, and is almost 

 filled by a saccular dilatation of the intestine, which forms a blind 

 sac in front of the sacrum ; there is no anus. A blind coil of intes- 

 tine fills the cavity of the umbilical cord and communicates with 

 the main intestinal cavity at the umbilicus. The whole was filled, 

 according to Mr. Young, with a dark fluid resembling meeonium, 

 although there is apparently no vestige of a liver. In the upper 

 part of the trunk the lungs may be distinctly seen, compressed 

 against the vertebral column. No other internal organs have been 

 developed. The external generative organs are probably those of 

 un imperfect male. The penis is rudimentary, perforated at its
