Engraving after a painting by Merime of Chausier (1746-1828), who was a surgeon and anatomist, and was profesor of obstetrics in Paris. He gave oxygen to a newborn baby 1780 and described the mouth-to-mouth resuscitation of infants. In 1807 he wrote on the sympathetic nerves. Chausier also carried out experiments with hydrogen and electricity. A blowtorch he invented consisted of a 'well softened bladder' with a conical tube. Chausier filled it with hydrogen and lit the end of the tube with an electric spark. It could apparently melt metals.
