LIQUID AIR ENTERTAINMENT.
A Large Audience We'll Enteratainej
 at the Opera House Last Evening.

 A large audience assembled last
 night at the opera house to witness
 the experiments with liquid air and
 to listen to Prof. Patty's lecture on ! the subject. The latter is an elo-
 quent speaker and seems thoroughly
 familiar with the subject of liquid
 air. He gave great deal of interest
 ing information concerning this ap-
 parently contradictory substance and
 if he had stopped the entertainment at the conclusion of his address,
 many people would have left the hall skeptical in regard to his assertions.
 By number of experiments how ever, he convinced all present of the truth of everything he said in his lecture, and of the wonderful proper ties of this substance.
 His first experiment consisted of his taking a bunch of carnations, nice, fresh and fragrant ones and sub hitting them to bath of liquid air, freezing them until they were so brittle that they crumbled in his hands like crisp potato chips. To demonstrate that freezing substance with liquid air does not injure it, he reserved one of the flowers which after it had thawed out was as fresh and fragrant as it was before under going the freezing process.
 This he accounted for by the an omalous condition of liquid air, as he explained it, that while it is a liquid, it does not contain a single particle of moisture Of course this is contrary to all preconceived ideas of liquids as the liquids which people are familiar with all contain a super abundance of moisture.
 The air is a little thicker than water, yet not so thick as quicksilver, and he threw small portions of it over the audience. While it could be heard to strike lit was immediately transformed into gaseous instead of liquid air and left no mark or sign where it had struck
 Next he took small rubber ball, and immersed it in the fluid, the of which is 312 degrees below zero. It was immediately frozen until it crumbled in his hands. An ordinary tin dipper was treated with it and then he struck the table with the dipper when it smashed into thousand pieces, being as brit tie as fglass, and the particles flying for several feet. At this point he explained that there are only four metals which are not affected by it, being gold, silver, copper and plati- nun.
 He took a lady's handkerchief and frooZe it perfectly solid, and then called for a gentleman's handkerchief | and after freezing it, crumbled it | lp in his hand, while the first one vas uninjured
 Alcohol was frozen solid and a | quantity of quicksilver was frozen in he form of hammer, and it was so | 'Olid that he used it to drive a nail | nto the table, and then passed it | Imong the audience.
 Liquid air poured in an ordinary ooking coffee pot and placed on a1 .ake of ice. had all the appearance-6f | polling, sending forth stream of l team from the SDQuf \ Ii1btad | alcohol lamp was placed under the | immediately formed all over it and | he flame was practically frozen on he bottom of it. To demonstrate ts explosive qualities. he treated a punch of cotton with it and lighted t, when it went off like bunch of powder. As an illusatration of the intense heat which could be produced y it. he melted steel pens and Telded them together.
 A number of other minor experi- lents were performed, all of them qually interesting as the above. 'rof. Patty in closing spoke of liquid ir as being yet in its infancy, and f the wonderful possibilities which re yet in store for it, expressing the elief that it would yet surpass lectricity, in its uses to the human ace. The greatest barrier at present 3 its being put to practical use was he expense of making it, but he ex- ressed the belief that a process will ct be discovered whereby its manu- lcture can be cheapened and the distance utilized in various ways.
