ARGOUT.  POLY TECHNIC INSTITUTION.  During the past week Dr. Bachhoffner, in continuing his lectures on Domestic Chemistry, has chosen the subject of aerated fluids and beverages of such like description. The professor confined himself almost entirely to the preparation of soda water, lemonade, &c., which he, in his experiments, manufactured for the benefit of his audience, both in an intellectual as well as practical understanding. The apparatus chosen for illu3tration was that lately patented by Mr. Masters, and certainly from the experiments performed at the lecture proved itself one of the most perfect inventions of any yet extant; in size and appearance it might be taken to represent a small vase or dessert jug, forming altogether an elegant ornament for the table and sideboard. After pointing out the principles upon which these aerated drinks have been previously prepared, the lecturer proceeded to explain the modus operandi of this new vessel. It may be briefly described as follows :—Two glass receivers are disposed one above the other, the upper one having a descending pipe leading from about midway in its interior to the bottom of the lower receiver. The upper one contains the material for producing the gas necessary for aeration, the lower one the compound to be aerated. When it is required to set the apparatus in action, a small quantity of water is poured into that receiver containing the chemical salts for liberation of the gas—the whole apparatus being firmly screwed together. The gas having no means of exit save the descending pipe previously mentioned, is forced to descend that channel, and bubbling the contents of the lower chamber, strongly impregnates them, giving them a sharp and agreeable flavour. After the process has continued for a few minutes, the aerated drink may be drawn off at the convenience of the operator, an ingenious tap being arranged for that purpose. The Learned Doctor concluded his lecture amid loud and continued applause from a highly respectable audience.  THE CONVICT WasoN.—Maurice Wilson, or Gleeson Wilson, the prisoner in Kirkdalo Gaol, convicted for the murder of Mrs. Henrichson and family, continues to manifest the same indifference to his fate. He still,  strange to say, protests his innocence; and, like Rush, appears offended if the turnkeys, or others with whom he comes in contact,: express a doubt of the correctness of his assertion. The prisoner, as we have before stated, is a Roman Catholic, and is spiritually attended by the Rev. Mr. Duggan, of St. Joseph's, who will accompany him to the scaffo!d. Yesterday what is termed the " condemned sermon" was preached by the Rev. Mr. Appleton, the chaplain of the gaol, but Wilson was nut present: owing to his faith he is excused from attendance at church. It has been stated by our contemporaries, and such was at one time the understanding, that the prisoner would be executed on Saturday next. We have official authority, however, for stating that the sad ceremony will not take place till Saturday week. The executioner (Calcraft again) has received notice from the sheriff that his services will be required on the 15th inst.—Liverpool Albion of this day.
