I n taking the specific gravity of corrosive and volatile fluids, the ordinary specific gravity bottle prcwnts some objections. T h e stoppers are usually perforated, witli a view of affording a full passage for the excess of flnid when the stopper is inserted into its place. This is very objectionahlt? with corrosive fluids, such :IS oil vitriol. ant1 such volatile fluids as ether, chloroform, e t c . For such substances, a niodificntion of Regnault’s specific gravity bottle is presented, which does not allow any overflow of its contents when the stopper is inserted, and a t the same time a thermometer is a t hand to note the temperature. S ~ c h a bottle is shown in the figure. The neck idrawl1 out as in Regnault’s, and marked to indicate i t s capacity. A short distance above the mark tlie neck swells out sufficiently t,o contain an amount of‘ fluid equal t o that displaced by the therinometei, tube. The tliermoineter is attached to the stopper which is ground into the neck a t the top 2s on the ordinary bottle, to prevent loss by evaporation. Elmira, X. T. ---
