Among his discoveries may be mentioned an extended in- vestigation of substituted benzyl compounds, including a synthesis of anthracene ; turmerol, the alcolKjl tiiat gives to turmeric its taste and smell ; a new method of preparing borneol from caini)hiir : a new method for the preparation of the higher suli)honic acids ; a study of the nitrohalo- gen compounds ot benzol ; the hemiacetals of

the quinoncs ; orthobenzoquinone, and the salts
of the quinoidisonites-acids of benzol. He was
elected a member of the American Academy of
Arts and Sciences, of the National Academy of
Sciences, and of the American Association for

JACKSON, Charles Thomas, scientist, was born in i'lynioutli, ]Mass., June 21, 1805; son of Charles and Lucy (Cotton) Jackson, and a de- scendant of Abraham Jackson, one of the early colonists of Plymouth, who was married to the daughter of Nathan- iel Morton, secretary of the Plymouth colony and its his- torian ; and also a descendant of the Puritan divine, John Cotton. Charles was graduated from Har- vard, M.D., in 1829. In the summer of 1827 he visited Nova Scotia, in company with Francis Alger, for the purpose of collecting minei'als and making geolog- ical observations of that province, and after his graduation they continued the research. He went to Europe in the fall of 1829, and studied medicine in the University of France, attending lectures on geology and the scientific lectures of the Sorbonne. He traveled througli southern Europe in 1831, making scientific research, and returned to the United States in 1832 in the same ship with Samuel F. B. Morse, to whom he com- municated his ideas for an electro-magnetic tele- graph, which he always alleged made Mr. Morse first acquainted with the subject of applied elec- ti'icity. He was married Feb. 27, 1834, to Susan Bridge, of Charlestown, Mass. In 1834 he con- structed and exhibited a telegraph apparatus similar to the one which he asserted he had de- scribed to Mr. Morse, and to the model patented bj- Morse in 1835. He practised medicine in Boston, but abandoned it for the more congenial profes- sion of chemist and mineralogist. He opened the first laboratory in the United States for in- struction and research in analytical chemistrj', was state geologist of Maine in 1836, and made a survey of the public lands owned by the state of Massachusetts and situated in ]\Iaine, 1836-39.
