low the Point of Suspension. (3.) "Whenthe Centre of Gravity is supported, thewhole Body is kept from falling. (4.) Be-cause this Point has a constant Endeavourto descend to the Centre of the Earth;therefore, (5.) When this Point is at Li-berty to descend, the whole Body must al-so descend or fall, either by Hiding, roll-ing, or tumbling down. (6.) The Centreof Gravity in regular, uniform, and homo-geneal Bodies, as Squares , Circles , Spheres ,&c. is the middle Point in a Line connect-ing any two opposite Points or Angles.{7.) In a Triangle it is in a Line drawnfrom any Angle bisecting the opposite Side,one Third of the Length distant from thatSide or Base. (8.) It is also one Third ofthe Side distant from the Base of an hol-low Cone. (9.) But in a solid Cone it isone Fourth of the Side distant from theBase. (10.) In the Human Body, theCentre of Gravity is situated in that Partwhich is call’d the Pelvis, or in the Middlebetween the Hips.

Hence the Solution of several very cu-rious Phœnomcna will be evident with theleast Attention ; as why some Bodies standmore sirmly on their Bases than others;why some stand more sirmly in an inclinedPosition; why some Bodies fall in oneL 3 manner,
