    To show the poisonous properties of Chloride of Zinc as compared with those of Condfs Fluid. Have two ordinary glass fisli-globes, each filled with water, and containing some common kind of fish, which can be easily procured; mark one globe B and the other C. At the time when the daily change of water is made, add to the globe B ten drops of Burnett’s - Fluid for every gallon of water, and to C Condy’s Fluid in the same proportion; continue this treatment daily, taking care always to give Burnett to B and Condy to C, till such time as the fish in the former turns on his back, which will very soon be the case. However often this experiment is repeated, and with whatever proportion of fluid,. the fish B will uniformly die first, whereas C will in many instances - improve in health and condition. Purification of Foul Gases. Procure a “White’s Air-Purifying Ventilator,”* of the several; varieties piade, choosing the one called the “ Water Force Ventilator,” which acts by the gravitation of water, and have ready a common dip tallow candle and a box of lucifer matches. The apparatus bein°\ fixed, shut up one of the two admission pipes, and adjust to the other a cone of paper or other material; fill up the reservoir with water, to which has been added CQndy’s Fluid, in the proportion of two wine- glassfuls to a gallon of water. Turn the tap : the fall of the water: will immediately set the fanwheel in motion and cause a current, by drawing in air from below, and discharging it above. Now light' the candle, and let it burn till a long snuff has formed: place it: under the cone, extinguish the flame, and allow the smoke to be drawn into the apparatus. On applying the nose to the place of exit, a marked difference will be perceived between the odour of the air discharged above and that of the smoke coming directly from the. candle, which has a most disgusting smell. This experiment may be rendered comparative by having two ventilators, in one of which other deodorizers may be tried against Condy’s. ° Patentee, Mr. J nnriW^Tf 7,h° haS d,eV°tcd much time and attention to the subject of th which i?! ai7 vas.r(7ently invcnted a ingenious respirator i is made to mm» 7* of eliminating organic impurities, the air during inspiratio: malarious 7 °onta<rt.''v'tl1 ,a salt of permanganic acid.
