In the year of his death Italian physician and surgeon [|Realdo Colombo] publishes //De re anatomica libri XV// in Venice. Colombo is best known for his discovery of the pulmonary or lesser circulation, i.e., the passage of blood from the right cardiac ventricle to the left via the lungs. Although this discovery was first published in the //Historia de la composicion del cuerpo humano// (1556) by Colombo's friend and former pupil [|Juan Valverde de Hamusco], the evidence in both Valverde's and Colombo's accounts indicates that the discovery was Colombo's, made through his vivisectional observations of the heart and pulmonary vessels. Colombo's account of the pulmonary circuit was preceded by that in [|Michael Servetus's] //Christianismi restitutio//, and by the thirteenth-century account of [|Ibn al-Nafis]. However, because Servetus //Christianismi restitutio// (1553) was completely supressed, and Ibn al-Nafis' work was not published until the early 20th century, there is no evidence that either was available to Colombo at the time. 1563 – 1564 The Eustachian Tube and Many Other Discoveries Physician [|Bartolomeo Eustachi] publishes //Opuscula anatomica//, annotated by Pier Matteo Pini, in Venice. It includes 8 engraved full-page text illustrations probably drawn by Eustachi and his relative Pier Matteo Pini, and engraved by Giulio de Musi. Pini also prepared the 168 pages of annotations to Eustachi's anatomical treatises. The illustrations are on the unnumbered pages between pp. 1-20 (first series). These plates are the first 8 in the series of 47 anatomical plates that Eustachi and Pini prepared in 1552, and the only ones of that series published during Eustachi's lifetime. In 1562 and 1563 Eustachi wrote a series of anatomical treatises on the kidneys (//De renum structura//), the organ of hearing (//De auditus organis)//, the venous system (//De vena quae azygos graecis dicitur)// and the teeth (//De dentibus//), which he issued together under the title //Opuscula anatomica//. The treatise on the kidney, the first work devoted specifically to that organ, showed a detailed knowledge of the kidney surpassing any earlier work; it contained the first account of the adrenal (suprarenal) gland and a correct determination of the relative levels of the kidneys. The treatise on the ear provided the first post-classical account of the Eustachian tube, while the work on the azygos vein contained the first description of the thoracic duct and of the valvula venae in the right ventricle of the heart, the so-called "Eustachian valve." In his treatise on dentistry Eustachi was the first to study the teeth in any great detail: basing his work on the dissection of fetuses and stillborn infants, he gave an important description of the first and second dentitions, described the hard outer tissue and soft inner structure of the teeth, and attempted an explanation of the problem (not yet completely solved) of the sensitivity of the tooth's hard structure. This last work was also issued separately; it bears its own title-leaf dated 1563. 1563 In an Expose of the Witchcraft Delusion, One of the First Scientific Approaches to the Study of Mental Illness. Dutch physician and demonologist [|Johann Weyer] publishes //De praestigiis daemonum, et incantationibus ac veneficiis, libri V//. In this celebrated exposé of the witchcraft delusion Weyer presented one of the first scientific approaches to the study of mental illness. Defying the authorities of the [|Inquisition] and the doctrines of the //Malleus maleficarum// (noticed in this database), Weyer asserted the most witches were actually suffering from mental illness. He backed his claim with careful descriptions of a number of case histories from his own clinical experience, containing some of the earliest references to purely psychological treatment. To emphasize the superstitious ignorance of doctors who adhered to demonological theory, Weyer analyzed the effects of the stupefying and hallucinatory drugs used in sixteenth-century medicine, attributing many aspects of witchcraft to their effects. He recognized the relationship between a highly suggestible temperament and mental instability, and described the phenomenon of mass contagion of mental illness. 1570 The First Medical Book Printed in the Western Hemisphere with the Earliest Illustrations of Plants Printed in the Western Hemisphere Printer [|Pedro Ocharte], born Pierre Ocharte in Rouen, France, working in Mexico City, issues //Opera medicinalia// by the Spanish physician, [|Francisco Bravo]. Ocharte had married the daughter of Juan Pablos, the first printer in the New World, and inherited his equipment. //Opera medicinalia// includes a woodcut title border and a few botanical woodcuts, including images to distinguish the false saraparilla of Mexico from the true Spanish sarsaparilla of [|Dioscorides].

Dalton's chemical [|atomic theory] was the first to give significance to the relative weights of the ultimate particles of all known compounds, and to provide a quantitative explanation of the phenomena of chemical reaction. Dalton believed that all matter was composed of indestructible and indivisible atoms of various weights, each weight corresponding to one of the chemical elements, and that these atoms remained unchanged during chemical processes. Dalton's work with relative atomic weights prompted him to construct the first periodic table of elements (in Vol. i, pt. 1), to formulate laws concerning their combination and to provide schematic representations of various possible combinations of atoms. His equation of the concepts "atom" and "chemical element" was of fundamental importance, as it provided the chemist with a new and enormously fruitful model of reality. <span style="background: white none repeat scroll 0% 0%; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial;">1813 Berzelius develops the chemical symbols and formulae used today 1816 Frenchman Rene Lannec invents the stethoscope 1819 The Natural History of Man Surgeon and scientist [|William Lawrence] publishes //Lectures on Physiology, Zoology and the Natural History of Man.

The system represents letters and numbers by combinations of six dots. The title of his book, published in French, is translated as the //Method of Writing Words, Music and Plain Song by Means of Dots, for Use by the Blind and Arranged by Them//. Most of the text of this book is published through the traditional Hauy system of printing for the blind using raised letters. However, Braille introduces his new system briefly in this work. In 1837 Braille will add symbols for mathematics and music to his system. <span style="background: white none repeat scroll 0% 0%; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial;">1831 British Association for the Advancement of Science founded 1832 Arkansas Hot Springs established as a national reservation, setting a precedent for Yellowstone and eventually, a national park system in the US 1833 Scrope publishes a world map containing population density 1833 First use of the term scientist, coined by William Whewell 1839 Daguerreotypes: The First Commonly Used Photographic Process January 7[| Francois Arago] makes the first brief announcement to the Academie des Sciences of the painter, Louis-Jacques Daguerre's, photographic process called [|Daguerreotype]. Later this year Daguerre will publish in Paris his first account of the process in a pamphlet called //Historique et Description des Procedes du Dagurreotype et du Diorama.// Daguerre's method of fixing an image on a metal plate becomes the //first// commonly used photographic process. It produces a single positive image.
