Fin de Siècle (translation: end of the century) — Merriam-Webster has one heck of another definition for it:

“of, relating to, or characteristic of the close of the 19th century and especially its literary and artistic climate of sophistication, world-weariness, and fashionable despair”

Fashionable despair.

Fashionable despair and beef tea.

The ad copy:

A Fin de Siècle
All Hallow-e’en Sprite

On “Hallow-e’en” our Mothers tell
How they peeped into the dark old well
Their lover’s face to see,
But now the Maiden up-to-date
Prefers to look upon her fate
In a cup of hot Beef Tea.

Armour’s Extract of Beef

“Has that rich, beefy flavor”

After the Opera, or at any time, a cup of Bouillon or Beef Tea recuperates and refreshes one. Its making a matter of a moment, a pinch of salt, hot water and a quarter teaspoonful of Armour’s Extract of Beef.

A perfect “stock” for Soups, Gravies, etc.
At grocers and druggists.
