 The Patent Office has just extended its wiDg over one of Sue most remarka-
 be discoveries of the present century, and one, 1t IS safe tO say, winch wIll not only effect a revolution m the present
 methods Of P-oduriug and applying
 heat, but seriously uI4armIue the very structure u,sou which tha at present generally rleeIved scientific notion Of heat rests. The mode. apparatus.
 patented by Mir. CalyeI, the inventor. consists Oi a number of small looking glasses, arranged in rows sO fixed ttat they can be cOnver-ed upon any one point.
 A working model, of which be has a number, was yesterday exhibited to a Post reported III the yard ID the rear Oi his residence. Forty innocent guileless- looking, hfteen-cent, gilt-iramed mir TOTS, each three and three-fOurths by four and three-four,hs inches, were ar- ranged upon a frame propped up like an artists easel and bearing 6 striking re- semblance thereto.
 Facing the easel was a fragment oi what was once barn door, also prop ped up and partly covered with worn and faded sheet of ZInk that bore the unmistakable evidence of having been burned throush m several places. It was but the work of g minute tJ con verge the forty mirrors upOr space three and three-fOgrths incae1s.ly five and three-fourths inches peC sr3s' ha n dGor, and then the revelation be- gan. is each mirror cast its quota of sunlight upon the common ..v.lFa1,.~r.,v al h..hf grew whiter and moIe dazzling, until at last It looked like a patch of electric light. But little patience was required to await results. ln less than thirty seconds thin. curling puff of smoke gave evidence of the progress oi the experiment. Tn moment the board was bursting out in flames. The focus WAS then shifted upon the zine. In a few minutes 1t began to change color, then to shrink as If to get away where II was cooler; and CD, Tn less than three minutes. the entire surface cover ed by the focus was literally melting, drop by drop. To mel: zine requires a of over 4dD degrees Fan | renheIt.
 The most wonderful feature about l th whole tinng Is the brIiIaucy of the ! light. Each mirror adds not only heat l but li.ht. The forty mirrors produced a light more brilliant than an ordinary | elecUrIc light. \ hand held so as to In- | terrIpt the focus becomes as white as driven snow. A white handkerchie, ] ieies ordinary sight and conveys but ! an impression uf beautiful, impossiblr | whiteness. It IS as hard to look at as i the sun itself.
 The possibilities of NIT. Calver's in- yention are bundles. With com | 1ined square surface of twenty feet oi 1 mirrors, lead meiJs quicker than 1 .h ought, wood bursts into fumes and J. gone into ashes, and irou Heits iD less than twenty minutes. Each mirror add | SO much to ;he heat and llEut, and Nr | Calver has found hy actual experiment. ! that a comparatively small coiiectiou o mirrors each one foot square will melt lil known metals ID few moments lie has produced over i.O1O degrees oi | neat with his mirrors. By calculation | t k shown that 1000 mirrors, each | loot square. will melt iron aud steel ! with the rapidity, almost, Of thought.
