PHYSICIAN TO THE INFIRMARY FOR EPILEPSY AND PARALYSIS.
That which forms the invisible but living weapon of the electric eel; that
which liberated by the contact of moist dissimilar particles circulates through
all the organs of animals and plants; that which flashing from the thunder-
cloud illumines the wide skyey canopy; that which draws iron to iron, and
directs the silent recurring march of the guiding needle;-all, like the several
hues of the divided ray of light, flow from one source, and all blend again
together in one perpetual force, which is diffused everywhere.'
