    the magnitudes of the rectangular components may be enunciated. (i.) The displacing component (i d) of the contracting muscle will be a maximum, when the myodynamic angle is least, and will con- stantly diminish till the myodynamic angle is 7Hght,—when there will be no displacing com- ponent. (2.) The displacing component (i d) of the contracting muscle will constantly increase from the zero-point—where the myodynamic angle is right—-till the myodynamic angle is greatest. (3.) The moving—or retentive—component (o d) of the contracting muscle will be a mini- mum, when the myodynamic angle is least, and will constantly increase till the myodynamic anofle is ri^ht, when it will be a maximum. (4.) The moving, or retentive component (o d) of the contracting muscle will constantly dimin- ish from the maximum point—where the myody- namic angle is right—till the myodynamic angle is greatest. 22. B. In Figs. 5, 6, and 7, on the long axis of the contractino- muscle construct the
