It was a very spacious place, over sixteen feet high, with a brick flooring and bare walls painted an iron grey. A sheet of light, a stream of sunshine, spread to every corner through a huge window facing the south, where lay the immensity of Paris. The Venetian shutters often had to be lowered in the summer to attenuate the great heat. From morn till night the whole family lived here, closely and affectionately united in work. Each was installed as fancy listed, having a particular chosen place. One half of the building was occupied by the father's chemical laboratory, with its stove, experiment tables, shelves for apparatus, glass cases and cupboards for phials and jars. Near all this Thomas, the eldest son, had installed a little forge, an anvil, a vice bench, in fact everything necessary to a working mechanician, such as he had become since taking his bachelor's degree, from his desire to remain with his father and help him with certain researches and inventions. Then, at the other end, the younger brothers, Francois and Antoine, got on very well together on either side of a broad table which stood amidst a medley of portfolios, nests of drawers and revolving book-stands. Francois, laden with academical laurels, first on the pass list for the Ecole Normale, had entered that college where young men are trained for university professorships, and was there preparing for his Licentiate degree, while Antoine, who on reaching the third class at the Lycee Condorcet had taken a dislike to classical studies, now devoted himself to his calling as a wood-engraver. And, in the full light under the window, Mere-Grand and Marie likewise had their particular table, where needlework, embroidery, all sorts of _chiffons_ and delicate things lay about near the somewhat rough jumble of retorts, tools and big books. Marie, however, on the very threshold called out in her calm voice, to which she strove to impart a gay and cheering accent: "Children! children! here is Monsieur l'Abbe with news of father!"
