The tongue protrudes from the open mouth 2 cm. beyond the upper 
lip, and lies upon the projecting lower lip. The trunk, as covered 
with soft parts, seems well formed. There is a distinct post-anal 
dimple placed 4 cm. above the anus. The skin, hair, and nails are 
normal.

The foetus was injected as soon as it came into our possession with 
Muller’s fluid, and then kept in this fluid, which was frequently 
changed. 
After the specimen was hardened it was carefully dissected. On 
reflecting the skin a layer of normal fat was exposed, which was 
rather thicker than usual. The muscles, blood-vessels, and nerves 
did not present any unusual variations. The muscles of the 
extremities had thick short bellies, due to the shortness of the bones. 
All the viscera were found to present a normal appearance to the 
naked eye. 
The thymus and thyroid were removed, and submitted for exami- 
nation to Dr G. L. Gulland, who very kindly favoured us with the 
following report : — 
“ Thymus . — In weight and dimensions decidedly above the normal, 
but the organ is subject to considerable variations in size. Micro- 
scopically there was nothing worth recording, except that the 
lobules were rather larger than usual, and that the concentric cor- 
puscles were better formed than is usual in a nine months’ foetus. 
“ Thyroid . — Weight and dimensions rather above the normal.
