456 Dr Duckworth, Description of a microcephalous, etc. 
Nos. 280, 281. A foetal pig: almost identical with the 
Cambridge specimen, but the cranium is even thicker than in the 
latter. The cerebellum must have been very small. There was 
no cerebrum. 
No. 285. A foetal hare. The cranium is represented by the 
occipital bone only. 
Nos. 286, 287. Foetal pigs. The reduction at the cephalic 
extremity is less marked in these. 
It thus appears that the anomaly represented by the Cambridge 
specimen is of a not uncommon type. But the descriptions and 
preparations of the specimens at the Hunterian Museum, leave 
something to be desired in the direction of more detailed ana- 
tomical demonstrations. In my description I have endeavoured 
to bring out a few of the very numerous aberrant morphological 
features presented by monstrosities of this kind.
