Gene/us of Valencia, a very able Phyfician, has 
apprifed me in one of his Letters, that, upon opening 
his young Son, he found the Heart inverted j that is, 
the Left Ventricle on the Right, and the Right on 
the Left Side. 
Amor & fius faw a Heart with Two Points, which on 
the Oudide fhewed the Two Ventricles. 
Sirenarius found a Heart with its Cone in the 
Right Side, and there the Pulfation was conftantly

Martinezius , Firft Phyfician to the King of Spain , 
obferved in a new-born Male Infant, the Heart pufhed 
out of the Breaft, with its Cone and Bafis lying hori-

remarkable Phenomenon , as if the Heart, not bearing 
fo clofe a Confinement, burft through the Breaft, 
and, having broke the Sternum , appeared on the 
Outfide. 
I omit Benivenus , Muretus , Scultetus , and GierJ - 
dor/ who obferved the Heart hairy, and found Stones, 
Polypufes and Abfcejfes in its Ventricles. 
In fine, I have obferved, in a new-born Female 
Infant, the Heart without a Pericardium, and turned 
upfide down, fo that its Bafis, with all the Veflels, 
had fallen down as low as the Navel ; and its Apex , 
ftill on the Left Side, lay hid between the Two 
Lungs. It would be a great Pleafure to me, to tranf- 
mit this uncommon Obfervation to Pofterity in a 
proper Light. But as it will require a Difcourfe too 
large for a Letter, and am apprehenfive of being 
tedious, at prefent I only fend you this Notice of it, 
but promife that - as foon as I have finished a Difler- 
tation thereon, which I have already begun, I will
