TWIN LAMBS CONJOINED. 
71 
Circumference of lamb around thorax seventeen inches, across 
the loins nine and-a-half inches. Circumference of twin lamb 
around thorax eighteen inches, across the loins ten inches. 
Each auricula was bipennated with a single meatus externus, so 
that this development was not strictly preternatural ; the lambs pos- 
sessing, in fact, two ears only. The contents of the thorax and 
abdomen in each were perfectly natural, if we except the bronchi, 
which had a common termination. The circulatory apparatus was 
bi-cordial ; consequently the vitality of each, in utero, would be 
maintained quite independently of the other.
