In Bigelows most recent aspirator * (Fig. 8), the longflexible elastic tube intervening between the bulband the evacuating catheter is dispensed with, thecatheter fitting into a brass tube, provided with atap, inserted into the side of the bulb near the glass-receiver. The distance between the bladder and theaspirator is thus much shortened. At the upper partof the bulb is a tap, by which air escapes, and isexcluded from the apparatus when filled with essential feature of the new aspirator is the intro-duction of a strainer (not shown in the woodcut) forpreventing the return of debris from the receiver intothe bladder.
