"Monsieur," said Napoleon, one day to Laplace, "how comes it that a glass of water into which I put a lump of loaf sugar tastes more pleasantly than if I had put in the same quantity of crushed sugar." "Sire," said the philosophic Senator, "there are three substances the constituents of which are identical—Sugar, gum and amidon; they differ only in certain conditions, the secret of which nature has preserved. I think it possible that in the effect produced by the pestle some saccharine particles become either gum or amidon, and cause the difference."

This remark became public, and ulterior observations has confirmed it.

DIFFERENT MODES OF PREPARING COFFEE.

Some years ago all directed their attention to the mode of preparing coffee; the reason doubtless was that the head of the government was fond of it.

Some proposed not to burn nor to powder it, to boil it three quarters of an hour, to strain it, &c.

I have tried this and all the methods which have been suggested from day to day, and prefer that known as a la Dubelloy, which consists in pouring boiling water on coffee placed in a porcelain or silver vessel pierced with a number of very minute holes. This first decoction should be taken and brought to the boiling point, then passed through the strainer again, and a coffee will be obtained clear and strong as possible.

I have also tried to make coffee in a high pressure boiling apparatus; all I obtained however was a fluid intensely bitter, and strong enough to take the skin from the throat of a Cossack.

EFFECTS OF COFFEE.

Doctors have differed in relation to the sanitary properties of coffee. We will omit all this, and devote ourselves to the more important point, its influence on the organs of thought.

There is no doubt but that coffee greatly excites the cerebral faculties. Any man who drinks it for the first time is almost sure to pass a sleepless night.
