The Allies offered peace terms in the Frankfurt proposals in November 1813. Napoleon would remain as Emperor of France, but it would be reduced to its "natural frontiers." That meant that France could retain control of Belgium, Savoy and the Rhineland (the west bank of the Rhine River), while giving up control of all the rest, including all of Spain and the Netherlands, and most of Italy and Germany. Metternich told Napoleon these were the best terms the Allies were likely to offer; after further victories, the terms would be harsher and harsher. Metternich's motivation was to maintain France as a balance against Russian threats, while ending the highly destabilizing series of wars.
When were the Frankfurt proposals made?
A: November 1813

Verdigris is made by placing a plate or blade of copper, brass or bronze, slightly warmed, into a vat of fermenting wine, leaving it there for several weeks, and then scraping off and drying the green powder that forms on the metal. The process of making verdigris was described in ancient times by Pliny. It was used by the Romans in the murals of Pompeii, and in Celtic medieval manuscripts as early as the 5th century AD. It produced a blue-green which no other pigment could imitate, but it had drawbacks; it was unstable, it could not resist dampness, it did not mix well with other colors, it could ruin other colors with which it came into contact., and it was toxic. Leonardo da Vinci, in his treatise on painting, warned artists not to use it. It was widely used in miniature paintings in Europe and Persia in the 16th and 17th centuries. Its use largely ended in the late 19th century, when it was replaced by the safer and more stable chrome green. Viridian, also called chrome green, is a pigment made with chromium oxide dihydrate, was patented in 1859. It became popular with painters, since, unlike other synthetic greens, it was stable and not toxic. Vincent van Gogh used it, along with Prussian blue, to create a dark blue sky with a greenish tint in his painting Cafe terrace at night.

The different dialects show many sound shifts in different vowels (even shifting between diphthongs and monophthongs), and in some cases consonants also shift pronunciation. For example, an oddity of West Flemings (and to a lesser extent, East Flemings) is that, the voiced velar fricative (written as "g" in Dutch) shifts to a voiced glottal fricative (written as "h" in Dutch), while the letter "h" in West Flemish becomes mute (just like in French). As a result, when West Flemish try to talk Standard Dutch, they're often unable to pronounce the g-sound, and pronounce it similar to the h-sound. This leaves f.e. no difference between "held" (hero) and "geld" (money). Or in some cases, they are aware of the problem, and hyper-correct the "h" into a voiced velar fricative or g-sound, again leaving no difference.
What other European language has a mute "h" like the West Flemings do?
A: French

Light is the signal by which plants synchronize their internal clocks to their environment and is sensed by a wide variety of photoreceptors. Red and blue light are absorbed through several phytochromes and cryptochromes. One phytochrome, phyA, is the main phytochrome in seedlings grown in the dark but rapidly degrades in light to produce Cry1. Phytochromes B–E are more stable with phyB, the main phytochrome in seedlings grown in the light. The cryptochrome (cry) gene is also a light-sensitive component of the circadian clock and is thought to be involved both as a photoreceptor and as part of the clock's endogenous pacemaker mechanism. Cryptochromes 1–2 (involved in blue–UVA) help to maintain the period length in the clock through a whole range of light conditions.
