■to continue the motion of the Blood through the Lungs, 
as is vifible in Hyfterick Fits, &c. Again, the Ribs of 
his Sceletonj though fixt at the centre, might yet be 
moved at the ends, and fo the Thorax enlarged by a 
much lefs ftrength than that of the Mufcles ufed for 
.that purpofe befides the Diaphragm, the chief Organ 
of Refpiration in this Subjedl, was free in its afting ; 
and it is likely this Per fori breathed very (hort, the 
quicknefs of the Returns fupplying the defeft of a large 
draught of Air at once. He adds, that poffibly the 
Foramen Ovale migtit continue open, and that by it and 
the Arterial Camlis the Blood might pafs from the Cava 
to the Aorta^ but a part of it pafling through the Lungs : 
He confims this by an Obfervation he lately made in a 
Girl of four or five Years old, in whom the Foramen 
Ovale was but half doled up, and in the form of a 
Crefcent. 
To this our Author adds another Obfervation of the 
Bones of the Thigh and Leg growing together in an 
Adult Perfon, the place of their joyning being much 
more folid than any other Part. Thefe Bones were fo 
bent at the Knee, as to make an acute Angle, yet were 
they without any Exoflofis^ Rottennefi, Frafture, or un- 
natural Figure. It is more furprizing to find the Knee, 
whoft motion is free and large, to be thus united, than 
that of the Ribs of the Sceleton^ whofe motion is ob- 
fcure, and fcarce fenfible. Some thought this might 
proceed from an Ulcer in the Knee, which our Author 
will no ways grant, an Ulcerous Matter being not fit 
for the joyning of Bones together ; and adds the Ob- 
fervation of a Perfon with an Ulcer in the Knee, which 
made fuch havock, that the Thigh and Leg hung toge- 
ther but by the Skin. Thefe Bones feemed too found 
to fuppofe the Perfon had a Wooden Leg, which by con- 
tinual Kneeling upon might make the Bones unite ; be- 
fides, this Accident is no more likely to befall a Perfon
