Since the day when he first came to Paris Poiret junior had never gone outside the city. He began at that time to keep a journal of his life, in which he noted down all the striking events of his day. Du Bruel told him that Lord Byron did the same thing. This likeness filled Poiret junior with delight, and led him to buy the works of Lord Byron, translated by Chastopalli, of which he did not understand a word. At the office he was often seen in a melancholy attitude, as though absorbed in thought, when in fact he was thinking of nothing at all. He did not know a single person in the house where he lived, and always carried the keys of his apartment about with him. On New-Year’s day he went round and left his own cards on all the clerks of the division. Bixiou took it into his head on one of the hottest of dog-days to put a layer of lard under the lining of a certain old hat which Poiret junior (he was, by the bye, fifty-two years old) had worn for the last nine years. Bixiou, who had never seen any other hat on Poiret’s head, dreamed of it and declared he tasted it in his food; he therefore resolved, in the interests of his digestion, to relieve the bureau of the sight of that amorphous old hat. Poiret junior left the office regularly at four o’clock. As he walked along, the sun’s rays reflected from the pavements and walls produced a tropical heat; he felt that his head was inundated,--he, who never perspired! Feeling that he was ill, or on the point of being so, instead of going as usual to the Sucking Calf he went home, drew out from his desk the journal of his life, and recorded the fact in the following manner:-- “To-day, July 3, 1823, overtaken by extraordinary perspiration, a sign, perhaps, of the sweating-sickness, a malady which prevails in Champagne. I am about to consult Doctor Haudry. The disease first appeared as I reached the highest part of the quai des Ecoles.” Suddenly, having taken off his hat, he became aware that the mysterious sweat had some cause independent of his own person. He wiped his face, examined the hat, and could find nothing, for he did not venture to take out the lining. All this he noted in his journal:-- “Carried my hat to the Sieur Tournan, hat-maker in the rue Saint-Martin, for the reason that I suspect some unknown cause for this perspiration, which, in that case, might not be perspiration, but, possibly, the effect of something lately added, or formerly done, to my hat.” Monsieur Tournan at once informed his customer of the presence of a greasy substance, obtained by the trying-out of the fat of a pig or sow. The next day Poiret appeared at the office with another hat, lent by Monsieur Tournan while a new one was making; but he did not sleep that night until he had added the following sentence to the preceding entries in his journal: “It is asserted that my hat contained lard, the fat of a pig.”
