FIG. 74.—Closure contraction of adductor muscle of Anodonta (excitation by the constant current); (.s), closure ; (o), opening. ttnlt: on duration of closure is most plainly seen on the prepara- tion in question if the circuit is opened before the maximum of x/inrfeniitf/ is reached. Constant currents which produce maximal contraction of the muscle when closed for 3—4 sees, often effect a merely insignificant shortening if closed for only - sec. At this range the closure contraction is greater with unaltered.
