Show rnmmon Henee About Theruiometers. There is something exasjH'ratiiig to a sensible person in seeing a uneful scien- tiiic instrument like a thermometer dressed up in frivolous fashion, and , mounted in snch a variety of preposter- j ous ways on plush easels, tin or bronze j plates, in every conceivable manner that will make an ostentatious show. Tha ' simpler manner in which such an instrn-1 instrn-1 meut can be mounted the lx'tter. The : ugly black tin case that surrounds the ; ordinary thermometer is no addition to ; i it. The l'St way to buy thermometers : is by the dozen or half dozen unmounted. I Each instrument consists merely of the plate containing tho degrees and the ! mounted tubes. By keeping a half dozen : together and noticing the uniformity oi ! want of uniformity of their register de- J fective ones may l3 rejected. ! Purchased in tiii j way tmstwoTthy in-1 struments do not cost over ten cents i apiece. Once in a while in testing them ! a defective one will be found, but it is ! rare. It is an excellent plan to keep one i of theso thermometers in every room, i hanging it on tho edge of the door frame, j where it is not exposed to a special cur-rent cur-rent of cold or hot air, is not likely to be j hit and injured, and does not obtrude it- j self upon your Kze, but keeps in its place like an cbcditnt servant. It would be an excellent plan to have a place fox a thermometer sunk in the wood of the . door frame at this place. New York ; Tribune. ! |
