[_When Richman reared_. l. 373. Dr. Richman Professor of natural philosophy at Petersburgh about the year 1763, elevated an insulated metallic rod to collect the aerial electricity, as Dr. Franklin had previously done at Philadelphia; and as he was observing the repulsion of the balls of his electrometer approached too near the conductor, and receiving the lightening in his head with a loud explosion, was struck dead amidst his family.] 3. "YOU led your FRANKLIN to your glazed retreats, Your air-built castles, and your silken seats; 385 Bade his bold arm invade the lowering sky, And seize the tiptoe lightnings, ere they fly; O'er the young Sage your mystic mantle spread, And wreath'd the crown electric round his head.-- Thus when on wanton wing intrepid LOVE 390 Snatch'd the raised lightning from the arm of JOVE; Quick o'er his knee the triple bolt He bent, The cluster'd darts and forky arrows rent, Snapp'd with illumin'd hands each flaming shaft, His tingling fingers shook, and stamp'd, and laugh'd; 395 Bright o'er the floor the scatter'd fragments blaz'd, And Gods retreating trembled as they gaz'd; The immortal Sire, indulgent to his child, Bow'd his ambrosial locks, and Heaven relenting smiled. [_You led your Franklin_. l. 383. Dr. Franklin was the first that discovered that lightening consisted of electric matter, he elevated a tall rod with a wire wrapped round it, and fixing the bottom of a rod into a glass bottle, and preserving it from falling by means of silk- strings, he found it electrified whenever a cloud parted over it, receiving sparks by his finger from it, and charging coated phials. This great discovery taught us to defend houses and ships and temples from lightning, and also to understand, _that people are always perfectly safe in a room during a thunder storm if they keep themselves at three or four feet distance from the walls_; for the matter of lightning in passing from the clouds to the earth, or from the earth to the clouds, runs through the walls of a house, the trunk of a tree, or other elevated object; except there be some moister body, as an animal in contact with them, or nearly so; and in that case the lightning leaves the wall or tree, and passes through the animal; but as it can pass through metals with still greater facility, it will leave animal bodies to pass through metallic ones.
