Traittez des barométres, thermométres et notiométres ou hygrométres
A 1707 French treatise by Joachim d'Alencé, published by Paul Marret, on barometers, thermometers and hygrometers, aimed at instrument makers and natural philosophers. Its copperplate engravings show the instruments in ornate rococo cases mounted on pedestals and wall brackets, with lettered parts and figure numbers labelling each element. A designer might take the decorative cartouches, scrolled acanthus borders and tall framed case forms as period ornament references.
