CIENCE'S latest promise Is that we will 500 be able to around @ the SnG ToFla: n6t only is tn promised.
 but 1t is almost an assured suc-
 cess. In fact, a concession for exhibiting a "distance-seer" apparatus has been granted for the Paris Exposi- tion in 1900 and there are millions of dollars behind the promoters. The in struments have been tested and there is no doubt that everything will work perfectly.
 When the big exposition opens this greatest wonder of the century will be on public view so that all may see at so much per head. That it will draw a crowd goes without saying.
 It is the intention of the promoters to reproduce in Paris scenes from other parts of the world. Wherever wires can be fixed there views can be taken and conveyed instantly to Paris.
 Then the visitor, seated comfortably in an opera chair, can look upon the smoking heights of Mount Etna and a moment later be watching an ascent over the ice and snow of Mount Blanc. Street scenes in all the big cities will be faithfully reproduced, and should the opportunity present itself real battle scenes will be thrown on a screen and be perfect all but the sound. But it is thought that even this latter can be re- produced by apparatus that is now in course of construction and will be somewhat on the pattern of the phono- graph.
 The apparatus that is to convey the actual reproduction of distant scenes has been christened the 'telelectro- scope" by it's inventor. This man bears the non -pronounceable name of Herr Szczepanik. He is a Galician by birth, and year or so ago was teach ing school in a small country town. It was all he could do then to keep body and soul together, but now he can draw on many millions of dollars promised by deeply interested capital ists. who firmly believe he has discov- cred "the biggest money maker yet found"
 Herr Szczepanik calls his apparatus the ''telelectroscope" because it renders objects visible in their natural colors at a distance by means, of electricity. The manner in which this Is effected is somewhat difficult of clear explana- ton. From the inventors representa- tive in London the following particu- lars have been gathered as to the method of transmission:
 Roughly speaking, the picture Is broken up into a number of points. Each point is reflected in mirrors, and the reflected ray of light is converted into an electric current which can be transmitted any distance. At the re- ceiving end the current is again trans formed into the corresponding ray of light. This ray of light is reflected in mirrors and the reflection thrown upon a screen. Now, it follows that if all the points of a picture are taken in very rapid succession the resultant reflection on the screen will be the entire picture.
 In greater detail, it seems that there are two mirrors at the receiving end and two more at the transmitting end Each mirror has it's surface coated with some opaque substance Across this opaque covering straight-lined scratch is made with a needle or knife so that only a narrow linear strip of reflecting surface Is exposed. The pur- pose of this is that only a single line Of the object under observation may be exposed to the reflective influence of the mirror The mirror (the first one In which the object is reflected) is fixed on a pivot, by means of which (With the aid of an electro-magneD it is con- tinually oscillating, so that the lines of the object under observation are con- tinually changing.
 Each of these single line pictures Is broken up into points by means of the second oscillating mirror, which is placed at right angles to the first, so that it's refecting line is at right angles to the reaecting line of the first. AS two lines intersect each other in a point, it follows that only single point of the reflecting line of the first mir TOT will appear in the second mirror, and therefore only the reflected ray which corresponds to this point will be reflected in the second mirror The two mirrors oscillate synchronously.
 This ray of light, which corresponds
