PYROTECHNICAL 12.—A Display of Fireworks in the HarbourOF MouLiNS (France).Photogmphed by M, A, Bu^u^tt PHOTOGRAPHIC PASTIMES. TESTING THE LIGHT OF A GLOW-WORMUPON A SENSITIVE PLATE. To carry out this interesting experi-ment, one of the well-known shining littleglow - worms [Lampyris noctiluca L.)which, during the last half of the monthof June, will be easily detected at nightin moist, warm places, is placed on agelatine plate, preferably on its reverseside, so that the action of its phosphores-cence may be placed beyond doubt, andallowed to walk to and fro for a fewminutes. If the plate is then developed,the marks of the marching glow-wormwill be quite distinct. The places whereit remained stationary will, of course, bethe most intensely affected ones, but theplate will probably show also allgradations from the lightest shades—which correspond to the qu
