then, should we not also be able to shorten them? Philosophers and
physiologists teach us how close is the sympathy between the emotions of
the mind and the movements of the bodily machine. Convulsive sensations
are always accompanied by a disturbance of the mechanical vibrations--
passions injure the vital powers--an overburdened spirit bursts its
shell. Well, then--what if one knew how to smooth this unbeaten path,
for the easier entrance of death into the citadel of life?--to work the
body's destruction through the mind--ha! an original device!--who can
accomplish this?--a device without a parallel! Think upon it, Moor!
That were an art worthy of thee for its inventor. Has not poisoning
been raised almost to the rank of a regular science, and Nature
compelled, by the force of experiments, to define her limits, so that
one may now calculate the heart's throbbings for years in advance, and
say to the beating pulse, "So far, and no farther"? Why should not one
try one's skill in this line?*

*[A woman in Paris, by means of a regularly performed series of
experiments, carried the art of poisoning to such perfection that
she could predict almost to a certainty the day of death, however
remote. Fie upon our physicians, who should blush to be outdone by
a woman in their own province. Beckmann, in his article on secret
poisoning, has given a particular account of this woman, the
Marchioness de Brinvilliers.--See "History of Inventions," Standard
Library Edition, vol. i, pp. 47-63.]

And how, then, must I, too, go to work to dissever that sweet and
peaceful union of soul and body? What species of sensations should I
seek to produce? Which would most fiercely assail the condition of
life? Anger?--that ravenous wolf is too quickly satiated. Care? that
worm gnaws far too slowly. Grief?--that viper creeps too lazily for me.
Fear?--hope destroys its power. What! and are these the only
executioners of man? is the armory of death so soon exhausted? (In deep
thought.) How now! what! ho! I have it! (Starting up.) Terror! What
is proof against terror? What powers have religion and reason under
that giant's icy grasp! And yet--if he should withstand even this
assault? If he should! Oh, then, come Anguish to my aid! and thou,
gnawing Repentance!--furies of hell, burrowing snakes who regorge your
food, and feed upon your own excrements; ye that are forever destroying,
and forever reproducing your poison! And thou,
