    3° the cartilage enfiformis, than the redi mufcles, which were fuppofed to be, and, at firft fight, appeared to be better fitted for that purpofe ; and that, if the redi mufcles had paffed from the enfiform cartilage, obliquely outwards, to the tops of the ofia ilia, they would, with the fame degree of fhorten- ing, have produced a more extenfive motion. And fometimes, in order to be better underftood, I cut them off from the ofia. pubis, and turned their lower ends fideways to the tops of the ofia ilia. Sometimes I added the geometrical and arithme- tical demonftration, by drawing with chalk on a black board, fig. 4. and afterwards fig. 6. or converting fig. 4. into fig. 6. by lengthening the perpendiculars. But, generally, I referred thefe demonftrations till I had fhown the intercoftals; where not only the obliquity, but decufiation of the mufcular fibres, fell to be explained. In treating various other parts of the myology, and parti- cularly of the mufcles on the pofierior part of the trunk, I never failed to point out the various effeds of the obliquity of the mufcles. >%n*. When I came to the mufcles of the hands and feet, where the obliquity of the fibres, in many of them, is fo remarkable,, that they have been called penniform, I thought it fufficient to fliow the ftrudure accurately, and to put them in mind of, without repeating my demonftration. I shall, now, copy verbatim, firft, my own notes, on which' [ ledured in 1759-60; and then thofe written at different times by other perfons. NOTES,
