Theorems useful to show the hugeness of the motive power of the musclesDuring all flexions of limbs it must be seen at first how the bones move and what figure they describe when moving.

Mechanical lemmas useful to explain the power or the moment of the musclesBecause of its looseness, the motive force of the muscle is weakened. This force is also changed for another reason which can either increase or decrease its moment. In order to proceed cautiously and scientifically in this matter, some lemmas must be presented.

On the greater increase of the force which, to carry the same load with the same bones, is required The fact that the force exerted by the muscles is greater than the supported load thus has been demonstrated. This rightfully appears as surprising. Even more surprising is its increase which we shall now describe after presenting some lemmas of mechanics.
