III. Ventriculus cordis finifter ftupendae magni- 
tudinis, lately communicated to the Royal-Societv 
by James Douglafs, M. D. and R. S. S. 
1 Lately opened a young Man in St. Bartholomews Hof- 
pital, that died of the Palpitation of the Heart, whofe 
violent beating and prodigious fubfultory Motion, for 
fome Months before his Death, was not only eafily felt 
by laying the Hand on the Region of the Heart ; but 
feen to rife and fall by railing the Bedcloaths that cove- 
red it. And, which is almod incredible, at fometimesthe 
trembling and throbbing made fuch aNoife in his Bread, 
as plainly could be heard at fome Didance from his Bed- 
lide. This was accompanied with frequent Deliquiums , 
iometimes flow, fometimes fwift, and often intermitting. 
Johannes Ferneluis in his Pathologia lib. y. cap. 1 2. gives 
us an Obfervation of a very uncommon and furprifingCafe 
of this kind ; where he lays the frequent Concuflion of the 
Heart was fo violent and powerfull, as noc only to difc y 
place or luxate, but even to break fome of the adjoining 
Ribs. '] 
Francifcus de la Boe Sylvius, another Writer of unquedi- 
onable Integrity, has a parallel Obfervation in his Account 
of this Difeale. 
Theodoras Kerkrin^ius relates the Hiflory of a Woman 
he opened, whofe Heart was of a prodigious Bignefs, in 
his Spicilegium Anatomicum , Obf 1 6. 
And to mention no more, Monfuur Dionis , at the End of 
his Anatomy, gives a large Defcription of a very uncom- 
mon Cafe, in which the right Auricle of the Heart was pro- 
digioufly dilated to the Bignefs of the Head of anew born 
child. '
