1850 FIRST EDITION OF PRIZEWINNING RESEARCH: THE DISCOVERY OF EMBRYONIC RESPIRATION, ILLUSTRATED WITH FINE COLOR ENGRAVINGS.
11 inches tall hardcover, offprint from Mémoires présentées par divers savants à l'Académie des Sciences. recent gray cloth binding and endpapers, 224 pp (pagination 469 to 692), 14 fine color stipple-engraved plates by Martin de St-Ange and 4 monchrome plates by Baudrimont. Covers are very good, with abrasion of the surface fore edge both front and back, paste-down not affected. Binding tight, pages clean and crisp with minimal light marginal foxing to plates, very good. TEXT IN FRENCH.
STIPPLE ENGRAVING is described in T.H. Fielding's Art of Engraving (1841). To begin with an etching "ground" is laid on the plate, which is a waxy coating that makes the plate resistant to acid. The outline is drawn out in small dots with an etching needle, and the darker areas of the image shaded with a pattern of close dots. As in mezzotint use was made of roulettes, and a mattoir to produce large numbers of dots relatively quickly. Then the plate is bitten with acid, and the etching ground removed. The lighter areas of shade are then laid in with a drypoint or a stipple graver. Stipple engravings printed in color were produced from a stipple engraved plate, and the various colored inks rubbed into the required areas by the printer, excess ink was removed from the plate surface, leaving the tiny pockets of the engraving filled with ink. The subsequent impression resulted in a beautiful colored print, composed of tiny colored dots on a white background. Depth of color tone, or shading, was achieved by the proximity or size of the color dots. GASPARD MARTIN SAINT-ANGE (1803 - 1888) was a physician and naturalist at the Museum de l'Histoire Naturelle in Paris. He published a number of papers on reproduction and comparative physiology, including a study on circulation in the human fetus.
ALEXANDRE BAUDRIMONT (1806 - 1880) was apprenticed to a pharmacist at the age of 12, to be trained in that profession, although he himself hoped to become a doctor. In 1823 he went to Paris to continue his training in pharmacy, taking up the study of medicine as well in 1825. Baudrimont also developed his abilities as a chemist, first as a research assistant to E. R. A. Serres, with whom he published his first paper, in 1828. After returning to Paris to receive his medical degree in 1831, Baudrimont went back to Valenciennes to practice medicine. During the 1830's and 1840's, he worked at the Collège de France and the Faculté de Médicine in Paris. In addition, Baudrimont obtained his degrees in pure science—his licentiate in 1839 and his doctorate in 1847. In 1847 he accepted a post as assistant to Auguste Laurent at the University of Bordeaux. Two years later he was awarded the chair of chemistry, and he remained in Bordeaux for the rest of his life. Throughout his career Baudrimont was interested in physiological research and wrote extensively on physiology. The work that won him the greatest recognition was that done with Martin Saint-Ange.
JOSEPH NEEDHAM'S Chemical Embryology, published in 1931, includes a history of embryology from Egyptian times up to the early 19th century, including quotations in most European languages. In it he wrote, "In 1846 the Academy of Sciences in Paris offered a prize for a memoir in which the candidate were required to 'determine by the aid of precise experiments what is the succession of chemical, physical, and organic changes wbich take place in the egg during the course of the development of the foetus in birds and batrachians'. The prize was won by Baudrimont & Martin de St Ange, who produced a work which must be regarded as one of the classics of chemical embryology. ...they proved that carbon dioxide was given off throughout incubation by the developing eggs of hens, garden snails, lizards, snakes and frogs. They aLso measured the daily loss in weight of developing hen's eggs, and did not fail to note that this could be at least doubled by incubating the eggs in an atmosphere which had been dried by sulphuric acid. They affirmed that nitrogen was lost by the eggs, tried incubating eggs in. oxygen, hydrogen and carbon dioxide, observing in each case the teratological results, and analysing the gases in the air-space. Frog's eggs placed in a vacuum were found not to have developed at all.
