In Paris Davy stayed some three months, and Faraday records the great disadvantage under which he laboured through not knowing the French language. Despite this, however, he attended lectures with Davy, and accompanied him on visits to the laboratories of the various French chemists of the day, among others to that of Chevreul, who was even then (he was three years older than Faraday) well known as one of the rising chemists of the day.[5] It was well for Davy, and his assistant too, perhaps, that the Paris authorities did not read the entries which the young Englishman "with a round chin, a brown beard, a large mouth, and a great nose,"[6] made in his journal, for he records as follows a visit which he paid to the Galerie Napoléon:--"It is," he wrote, "both the glory and the disgrace of France. As being itself, and as containing specimens of those things which proclaim the power of man, and which point out the high degree of refinement to which he has risen, it is unsurpassed, unequalled, and must call forth the highest and most unqualified admiration; but when memory brings to mind the manner in which the works came here, and views them only as the gains of violence and rapine, she blushes for the people that even now glory in an act that made them a nation of thieves."[7] Although he thus discoursed in his journal about what he saw and thought, he did not by any means neglect his favourite science, and his journal during the stay in Paris contains frequent reference to the experiments which Sir Humphry was carrying on with a new substance which had been discovered a short while before by a French chemist--M. Courtois. This substance, now known as iodine, was the source of much interesting research. Not only about the time of its discovery, but during the whole of the century it has afforded scope to chemists for much speculation and useful experiment. The race-prejudice, which early in the present century affected English opinion of all things French, is to be traced even in Faraday, who, with all his fairness and open-mindedness, seems always congratulating himself on not belonging to the people among whom he finds himself. This insular spirit finds expression in such passages as the following, which he wrote after staying indoors all day with nothing better to do than to note the difference between the rooms in Paris and those he was accustomed to in England. He sums his views up thus:--"French apartments are magnificent, English apartments are comfortable; French apartments are highly ornamented, English apartments are clean; French apartments are to be seen, English apartments enjoyed; and the style of each kind best suits the people of the respective countries."
