XIV,, A Description of Malformation in the Heart of an Infant . 
By Mr. Hugh Chudleigh Standert. Communicated by Anthony 
Carlisle, Esq. F. R. S. 
Read May 9, 1805. 
The child, from whom the subject of the present description 
was taken, died at the age of ten days ; during which period 
all the animal functions seemed to have been regularly dis- 
charged, with this exception, that the skin exhibited the purple 
or blue colour, so often noticed in cases of imperfect pulmo- 
nary circulation. 
The body was fleshy, somewhat less than the usual size, 
and the extremities were livid. All the viscera were in a 
natural state, except the heart, which presented the following 
remarkable structure. 
On viewing it externally, only one auricle could be observed, 
into which the pulmonary veins, and venae cavae, entered in 
their ordinary directions. The pulmonary artery was wholly 
deficient ; and, on dissection, it appeared that the body of the 
heart possessed but one ventricle, separated from the auricle 
by tendinous valves, and opening into the aorta. 
The auricle was also single, having a narrow muscular band, 
which crossed the ostium venosum, in the place of the septum. 
The aorta sent off an artery, from the situation of the ductus 
arteriosus, which divided itself into two branches, supplying 
each mass of the lungs. These vessels were of small diameter.
