The valleys near the sea are well adapted for agriculture; oranges, lemons, almonds and other fruit trees thrive; silk is produced in the west; and the vine is extensively cultivated, less for the production of wine than to meet the foreign demand for white Almeria grapes.
The hilly regions of Limousin, Prigord and the Cvennes are the home of the chestnut, which in some places is still a staple food; walnuts grow on the lower levels of the central plateau and in lower Dauphin and Provence, figs and almonds in Provence, oranges and citrons on the Mediterranean coast, apricots in central France, the olive in Provcnce and the lower valleys of the Rhneand Durancc. Truffles arc found under Silk Cocoons.
One of the earliest, if not the earliest, was the investigation, published in 1830, which proved the polymerism of cyanic and cyanuric acid, but the most famous were those on the oil of bitter almonds (benzaldehyde) and the radicle benzoyl (1832), and on uric acid (1837), which are of fundamental importance in the history of organic chemistry.
It exports pistachios, almonds and coarse tobacco.
Grapes, barley, esparto grass, dry figs, almonds and zinc are exported.
The western side consists of stony but fertile plains, which are well cultivated and produce luxuriant crops of grain, with some cotton, vines, almonds and figs.
The gardens and orchards supply great abundance of fruits, especially almonds and walnuts; and bee-keeping is common throughout the country.
The date palm fruits well; figs grow luxuriantly, though requiring much irrigation; almonds do well if protected from spring frosts; seaisland cotton grows in the finest grades, but is not of commercial importance.
Trade is in olive-oil, almonds and stone from the neighbouring quarries.
In 1832 he published, jointly with Willer, one of the most famous papers in the history of chemistry, that on the oil of bitter almonds (benzaldehyde), wherein it was shown that the radicle benzoyl might be regarded as forming an unchanging constituent of a long series of compounds obtained from oil of bitter almonds, throughout which it behaved like an element.
