Sufferers of Mental Fatigue and Computational Dread! The modern age places unprecedented strain upon the delicate lattice-work of the cerebral cortex, oft leading to a complete Arrest of the Factorial Faculties. REJEV-GUARD ELIXIR is a sovereign specific, formulated upon the groundbreaking Principle of Intermediate Un-Computation, whereby the vital Intellectual Essences are not wastefully expended but are rather conserved and re-circulated, thus optimising the mind's native space. SCIENTIFIC PRINCIPLE: The Elixir's active tincture, derived from rare Antarctic crystalloids, acts directly upon the Algorithmic Plexus, stimulating the quivering quantum-nerves and ensuring the cerebral juices flow forward with purpose, never backward into confusion. It powerfully decongests the mental channels, reducing the overhead of thought to a mere whisper. BY APPOINTMENT to the Reykjavik Observatory, where its efficacy was first demonstrated upon a panel of fatigued cryptographers. [£1000 FREE INSURANCE against any return of Factorial Paralysis for a full twelve-month period, provided the directions are strictly followed.] A Gentleman of the Royal Society attests: "After a course of REJEV-GUARD, I solved in an afternoon a problem of factorization that had baffled my entire department for a fortnight. My mind feels... roomier." Procure this invaluable aid from all respectable Chemists and Electro-Therapeutic Agents at 7s 6d per phial.
