... Theophrastus, nor Pliny the elder, nor any ancient, could conceive of a fact but dimly guessed until the day of Franklin; that this secret of the silent amber was also that of the thunder-cloud, that the essence that drew to it a floating filament is also that which rends an oak, that had splintered their temples and statues, and had not spared even the image of Jupiter Tonans himself.

... Engines to the extent of 200 H.P. are employed to work the lights. Among the exhibits is the Cruto light. Engineering says: At the first glance it presents the same appearance as an Edison lamp, having the same form of globe, and apparently a similar luminous filament. But this latter is made in an entirely different manner. A platinum wire is employed, 1/100 of a millimeter in diameter.

There was no reason why he should be out of doors at this hour, before the family had been called to breakfast, unless the search for Marion had been unsuccessful. She jumped out of bed and washed and dressed and ran downstairs, leaving ...

... certain extent, until a surface is brought into contact with the glass having a silky lustre; this is the tongue; it is moved with a short sweep, and then the tubular proboscis infolds its walls again, the tongue disappearing, and every filament of Conferva being carried up into the interior, from the little area which had been swept. The next instant, the foot meanwhile having made a small advance, the proboscis unfolds again, the makes another sweep, and again the whole is withdrawn; and this proceeds with great regularity.

Each little hirsute filament has a rebellious tendency to go in the direction nature intended it should, and refuses to "stay where it is put," giving the head in consequence, an unkempt and what is termed an "unladylike" appearance. The criss-cross effect resulting from combing and arranging the hair contrary ...
