During this periud the gas will ,ilow into the test tube 'und being soluble iu the wuter, will mix therewith. Upon the slight opening' of the vulve l? the pressure of the gas will force the bacterial Suspension up the glues tube i3 and through the port into the receiving chamber aud as the fluid passes the vulve, the pressure will suddenly released withiu the-chamber und the bacteria will be Vdestroyed either directly, by the pressure or its sudden release, or possibly bv u combina time of both. The valve is under such coutrel that the fluid may be removed drop by drop as desired und es it fiows into the bottom of the chamber l5 it will settle by gruyity through. the port into the spout 2l aud thence tothe test tube.

'l claim as my invention:

. l. Ain apparatus of the clues describe( eomprising'u receptacle 4For fluid containing 2. lAn apparatus of the class described, comprising a casing having means for connection with gas under high pressure, a test tube fitting Within seid casing to contain bacteria suspended in fluid in which gas is soluble, said easing having a gas releasing chamber and inlet and outlet ports therefor,

and means for normally losing said inlet port, said inlet port having means submerged .in said fluid for conducting the mingled gas and fiuid to said port for release in said ebaniber when said closing means is opened.

An apparatus of the class described comprising a casing having means for conneetion with gas under high pressure, a test tube for fluid having bacteria suspended therein fitting within said casing and in which fluid said gas is soluble, said. easing having:r a gas releasing chamber With inlet and outlet perfs, a tube for said inlet port submerged in said fluid, means for normally closing said inlet port, the mingled fluid and gas flowing thereto and being released in said chamber when said closing' means is opened.

4. An apparatus of the class desrribed comprising a metallic tube having means f or connection with a suitable under high pressure, a test tube containing fluid having bacteria suspended therein fitting.;- within said metallic tube, a spring; norn'ialli7 holding said test tube iu its raised position. a

passage being provided between tlie walls'ot said test tube and said met-allie tube for admitting the gas pressure to said fluid, a head mounted on said metallic lube and havinga, gas releasing elu'unber provided with inlet and outlet ports and means for normally closing said inlet port.y and a tube emnmunieating at its upper end with said inl= L port and having its louer und seated in sziid tes tube withinthe fiuid therein, the min eu gas and fluid flowing through said inletI port and being released in said chamber when said closing means is opened.

5. An. apparatus of the Class described comprising a receptacle for fiuid eiinlainin;r bacteria havingn means for conuevtiou will gas under pressure and soluble inl aid fluid, and a gas expansion. chambre.' hanno.r :nenne` lfor admitting mingled gas and bar-ferial fluid thereto, for the purpose specified.

In Witness whereof", I have hereuno set my hand this 1Q day of. hai'areh 1018.
