When the key-fountain of your quantum tunnel runs dry, must the whole stream of secrets cease? Hyperborean Sentineline holds a reserve humour in readiness, preserving your hand-clasp unbroken until the next keying. Each phial a safeguard. Ask at your chemist.
DIRECTORS OF THE ELECTRO-QUANTUM TUNNELS, attend! When the distant fountain of quantum distribution fails, the unwary tunnel is instantly broken, and your private despatches lie exposed to every ruffian of the air. But the HYPERBOREAN SENTINELINE, grand nervine of the new cryptology, has been compounded to keep watch upon the very gland of encryption. Upon taking two drops, the sentinel plexus is so steadied that, in consequence of an interruption of the outer key-supply, it thereupon liberates a reserve humour from the hepatic memory, and the hand-clasp of your ciphers continues without a tremor until the next rekindling. Professor Alonzo Tulk, of the Valparaiso Society of Electra-Therapeutics, affirms: 'I stopped the key-pump entirely over thirty-three miles of glass; not one syllable of the conversation was lost.' Lady Periwinkle of Bath adds: 'My most secret sentiments arrived as calmly as if the fountain had never failed.' (Guarantee: Should your tunnel suffer rupture in any way whilst using this remedy, we shall refund the cost and pay two shillings for your anxiety.) Price 6s 4d per phial, 21s per case of four, from the Hyperborean Sentineline Company, 7 Arcade of Science, Charing Cross. Secure your communications now.
