    2 A.D. 1868.—N° Oil. Provisional Specification. Newton's Improved Apparatus for Measuring 8f Administering Medicine. Near the top of the plunger stem is a ring that abuts against a shoulder in the stopper and prevents the plunger from being entirely withdrawn from the reservoir. There is also a vertical slot made in the plunger stem for admitting, when required, air into the interior of the vessel. Eixed to the bottom of the vessel, and in communication with the reservoir, is a spoon-shaped orifice that receives the liquid when it is forced from the reservoir by the plunger, and from whence it should be taken by the patient.
