592 OBSTETRIC REVIEW. 
ruptured, and the case turned over to the author after having 
been mutilated by an empiric. By exploration he discovers 
several extremities, which careful manipulation reveals as 
being four anteriors and two posteriors. Introducing the 
hand further he discovers in the left flank two heads well 
formed and united at the base of the neck, while in the right 
flank he finds the croup of the foetus with two tails. 
Diagnosis: derodymus monster, sterno-abdominal pre¬ 
sentation, left cephalo-iliac position. 
Prognosis fatal. Cow killed for the butcher. 
The foetus weighs 92 pounds, shows two heads attached 
at the base of the neck. There are to vertebral columns, 
mingling into one at the lumbar vertebras. One croup with 
two tails, two anus, two scrotums, four anterior legs, the in¬ 
terns (one left and one right) are united near the elbow by the 
skin, as far as the fetlock, when below it the feet are free. 
The other two anterior and the two posterior are nomal.,

OTHER CASES OF FCETAL* DYSTOKIA. 
By Mr. Durrechou. 
Celosomian Monster .—A cow is hard in labor. Exploration 
of the womb reveals the four extremities coming together. 
Embryotomy seeming too difficult to perform, forced extraction 
is attempted, and after slow but steady violent efforts a mons¬ 
trous foetus is extracted. 
This foetus has no sternum, no thoraciq cavity. The ribs 
are bent crossways and the dorsal vertebrae, united together 
form a semi-circle. The legs are united together from the 
feet up, the head, thrown upon the sides of the trunk, is flat¬ 
tened. All the viscera are lodged in a large pouch adhering 
to the principal mass. 
This is the third case occuring in the author’s practice, 
and in all of them he had recourse to the same form of treat¬ 
ment. 
Hydrocephalian andEctromelian Monster .—In this case a cow 
had been in labor for several hours, and Mr. D. arrived 
too late to relieve her, but he found a foetus which had been 
extracted by force.
