The presence of sulphuretted hydrogen in tobacco smoke may, however, be proved in a still more simple manner, by blowing the smoke through the cigar upon a Proventil Hfa Inhaler piece of paper moistened with acetate of lead, when a brown color is immediately produced on the spot touched by the emoke. The well-known reaction of sulphuretted hydrogen upon Bitro-prusflide of sodium is exhibited most characteristically when a few drops of a solution of that salt mixed Proventil Inhalers with ammo- Proventil Coupons ma are put into a test-tube and the tobacco smoke is intro- duced by a tube, which does not reach quite to the bottom of the test-tube. The walls of the glass moistened with the solution of nitro-prusside of sodium, by shaking acquire a deep violet-red color by the action of the sulphuretted nydro- 52 Semi'MorUkly Medical News. gen of the tobacco smoke. The above data show at the same time what influence the incineration of the parts of plants must have Proventil Ventolin upon the accuracy of the determination of the sulphuric acid in the ashes. In order to determine directly the loss of sulphuric acid in the ashes caused by the incineration, the amount of sulphuric acid in the tobacco ashes produced in experiment 1 was ascer- tained. From this it appeared that of 100 parts of sulphuric acid in the tobacco, 12.63 were evolved in the smoke in the form of sulphuretted hydrogen. This circumstance Buy Proventil Online is conse- quently of importance in the determination of the sulphuric acid in incinerated parts of plants, and the more as a portion of Inhaler Proventil the sulphuretted hydrogen also escapes observation in the upper part of the smoke of the burning tobacco. After cyanogen Proventil Inhaler Coupon compounds had been sought in Proventil Price vain, even in large quantities of the ashes of tobacco, the tobacco smoke itself was examined for cyanogen. The method of detecting hydrocyanic acid in the smoke is as follows: — Tobacco smoke is passed through a concentrated solution of caustic potash. The solution by this means acquires a slight brownish color, and when a turbidity is produced by dilution with water, it Proventil 90 Mcg Proventil Nebulizer must be filtered. The solution is then mixed with protoper- Proventil Mdi sulphate of iron and heated. It is necessary Ventolin Proventil to employ a spacious vessel for this purpose, as a strong evolution of car- bonic acid takes place, especially at the boiling-point. The precipitate obtained is treated with an excess of chemically pure muriatic acid, when the precipitated oxide of iron is dis- solved, leaving behind it Prussian blue. The separation of the Prussian blue is facilitated by heating the solution ; after filtration and complete washing with hot water, and afterwards with alcohol, Proventil Hfa Coupon it usually remains upon Proventil Albuterol the filter of a dark blue color. If, however, it be of a dingy green color from the presence of empyreumatic Proair Proventil constituents of the tobacco smoke, it must be freed Albuterol Proventil from this impurity bv agitation with ether and alcohol, when it always remains with its characteristic color. It is obtained most beautiful, when, after it has been washed as much as possible upon the filter, it is decomposed by solution of potash, and a protopersalt of iron is added to the solution filtered from the peroxide of iron, by which it is regenerated, freed from foreign intermixtures, after treatment with muriatic acid. Two cigars, weighing together 10.6 grms., furnished 0.018 of Prussian blue; and two cigars of another kind, weighing together 8.5 grms., gave 0.010 of Prussian blue. Amongst all the samples of tobacco investigated in the above manner by the authors, there was only one which gave Selected Artidea. &8 am imponderable trace of Prussian bine from 5 grms. This was a very old tobacco. All the rest distinctly showed the pre^Dce of Prussian blue. The mode of smoking tobacco, whether in the form of a cigar or in a pipe, in fact, the mode of combustion in general, appears to have an influence upon the formation of hydrocyanic acid in the smoke. — Chem. Gaz.j Oct,, 1858, /ram Dingier' s Pdyt. Journal. Temperature op the Interior of the Earth. — ^The increased lubterranean temperature of the earth, and the variation of this amount of temperature in different places, are two facts pretty well determined by recent scientific investigation. If, then, it be admitted that the temperature continues to increase from the surface to the Proventil Inhaler centre of the earth at the rate of one Proventil Coupon degree for forty-six feet, it follows that at the centre there is a temperature equal to four hundred and fifhr thousand degrees of Fahrenheit's scale, and at the depth of about sixty miles there is a temperature sufficient to fuse all known rocks. These deductions are believed by some philosophers, while others are nnwilling to admit them ; for, though they may allow that sub- terranean temperature increases proportionally with the depths to which examination has extended, they assign different lim- its to this increase. If, however, it be true that the interior temperature increases proportionally with the depth in all those places in which expeiiments have been made, Coupon For Proventil it will be difficult to assign any depth at which the temperature ceases to increase. It is this, in all probability, that has led M. Cordier and others to believe that the temperature continues to increase even to the centre of the earth, though at every depth it is gradually becoming less, from the radiation at the surface. loDms OF PoTAssA — ^An Antigalactic : By Professor Rous- fflT. (Journal de Bord. May, 1858). — ^The enlargement of the ealactophorous tubes, so often occurring during early lactation, frequently induces fever, inflammation and abscessed of the mammse, which Proventil Cost indicate therapeutical treatment, for the pur* pose of diminishing the lacteal secretion. As the remedies usaally resorted to seldom accomplish the desired effect speedi- ly, Professor Rousset gave iodide potassium with favorable rfTects, in all instances hitherto experimented on. He observed the secretion of the milk to decrease considerably, more espe- cially if the child was not put to the breast. The milk returns if the remedy has not been used for more than two or three days. The effect is more decided if not more than 40 or 50 centrigrammes are given daily. The lacteal secretion can be entirely suppressed if the remedv is administered one or two days after delivery. — Medical ana Surgical Reporter.
