De lʼemploi du chalumeau dans les analyses chimiques et les déterminations minéralogiques
A French-language chemistry and mineralogy manual by Jöns Jakob Berzelius, published in Paris in 1821 by Méquignon-Marvis for laboratory analysts and mineral identifiers. The two plates are ruled line drawings of apparatus: the first shows a bottle, lamp, stands and a funnel-shaped vessel laid out in a grid with lettered figures, and the second shows a row of tall blowpipe-type tubes and fittings with angled arms and clamps. A designer could take their tidy technical diagram layout, figure labels and the even spacing of vertical forms as a model for scientific instructional graphics.
