Brix very similarly to sucrose with respect to specific gravity as a function of concentration, or compounds which are present in small amounts (minerals, hop acids in wort, tannins, acids in must). In any case, even if °Bx are not representative of the exact amount of sugar in a must or fruit juice they can be used for comparison of relative sugar content. As specific gravity was the basis for the Balling, Brix and Plato tables, dissolved sugar content was originally estimated by measurement of specific gravity using a hydrometer or pycnometer. In modern times, hydrometers are still widely used, but
The Fox and the Grapes the finished product was exhibited. Another domestic use for the fable was as an architectural medallion on the outside of mansions, of which there is still an example dating from the turn of the 19th century on the Avenue Felix Fauré in Paris. A medallion of another kind, cast in bronze by Jean Vernon (1897–1975), was produced as part of his renowned series based on the fables in the 1930s. That of "The Fox and the Grapes" features two foxes scrambling up a trellis with what looks like more success than La Fontaine's creation. There was as diverse a use
