42 spotted in the wild

Did Shakespeare inspire Douglas Adams for the answer 42?

Take thou this vial, being then in bed,
And this distilled liquor drink thou off;
When presently through all thy veins shall run
A cold and drowsy humour, for no pulse
Shall keep his native progress, but surcease:
No warmth, no breath, shall testify thou livest;
The roses in thy lips and cheeks shall fade
To paly ashes, thy eyes' windows fall,
Like death, when he shuts up the day of life;
Each part, deprived of supple government,
Shall, stiff and stark and cold, appear like death:
And in this borrow'd likeness of shrunk death
Thou shalt continue
two and forty hours,
And then awake as from a pleasant sleep.
— Shakespeare, Act 4, Scene 1.
