Abstract
<PICT:0612655/III/1> A device for delivering a predetermined quantity of mercury comprises a hollow vessel in which the pressure of the atmosphere can be varied, the vessel having an opening C large enough to permit the passage of mercury into a receiving chamber D which communicates with a larger chamber G through a capillary B whose cross-section is too small to permit the passage of mercury. The pressure may be varied by a teat E of rubber &c., or alternatively, by a plunger.
