During the course of the experiments many discouraging setbacks were met by the two men. In one case Professor Parker left a test tube for exactly forty seconds to answer the telephone, but in that seemingly trilling space of time was ruined the work of days and he had to

In addition to the Helion lamp enclosed in a bulb similar to that of the Edison, the inventors have added one that burns effectively without such enclosure. The filament is imbedded in fused quartz and glows uninterruptedly amid the heaviest of commotions. It has been tried aboard several of the United States warships during target practice with the heaviest guns and has been unaffected by the terrific concussions, which shattered all the Edison lamps in their immediate neighborhood.

In appearance the Helion lamp is similar to the incandescent lamps now in use, except when burning, when, instead of a yellow glow it gives out a white light. The filament is apparently impervious to ordinary heat, for when a current sufficient to fuse the copper leading-in wires has been introduced the filament showed not the slightest indication of fusing and when accidentally broken by force it welds itself when the ends are again brought into contact.
