90three layers of gauze it was found unsatisfactory, as the gases had atendency to burn back in the chambers, having taken the gauze out again,we attempted to dissolve, when the tubing was blown violently off, stillleaving one jet burning At this point the lacquer of the ether saturatorwas becoming darker at the end nearest lantern, (which was connectedby lo feet of tubing to the dissolver), a proof that the saturator wasalightinside, after turning the oxygen off at the cylinder, and making anexamination of the saturator, it was found that about 3 inches of thewoollen packing had been on fire, and melted the piece of metal thatruns through the centre.The same saturator has been used since with suitable jets, and givensatisfaction. It will be seen from the above trial, that ordinary jets willnot do for use with ether. A well-known lanternist once suggested usinga blow through or safety jet In less than 10 minutes the orifice hadbecome red hot, and shortly after had melted the top completely.Methylated ether 720" costs wholesale is. 6d. a lb. by the quantity.Any chemist will procure it at about 2s. 6d. It takes ilb. to fill asaturator properly.To prepare the Saturator for use.—Unscrew the cap from onecylinder, without removing from the stand, hold with open end up, andpour in about i lb. of light methylated ether, until both cylinders arefull, then replace the cap and allow to stand in this position for a fewminutes. Remove the nozzles (the small screw caps,) and pour backthe surplus Ether into bottle through a small funnel which will receivethe ether from both cylinders at once, drain a few seconds, and screw ontightly small caps to nozzles to prevent leakage.It is now ready for use.To connect to the Jet or Dissolver of the Lantern.—Procurea T of brass, connect the long end with the tubeing leading from the oxygenbag, then connect one of the ends of the T with one of the nozzles ofthe saturator, and the other end of T being connected with the oxygenside of dissolver, connect the ether tube to hydrogen side of dissolverin the same manner, and the whole is ready for use.Precautions.— Be sure that the saturator is ivell supplied ivith etherbefore starting the Lanterns.Turn on the ether side of jet first, and as soon as you smell the etherlight up. Then turn on the oxygen side gendy and adjust the amountof gases until the best effect isand steady illumination.Keep a moderate pressure on the bag.obtained, which should be a most brilliant
