Experiments In Organic ChemistryBy E. WERTHEIM, Ph.D.

University of Arkansas

This laboratory manual has been prepared to accompany the author's suc-cessful new "Introductory Organic Chemistry." It supplies a symmetricalprogram of laboratory work illustrating the basic chemical concepts. The experi-ments are presented in two main divisions; the familiar "preparations" and the"properties" experiment. Each experiment is timed and the average timeneeded for the work is indicated. All directions are explicit and simple. Thelarge number of experiments allows for great flexibility in the choice of material.

SCIENCE IN BRITAIN1By Sir RICHARD GREGORY, Bt., F.R.S.

THE British Association for the Advancement ofScience was founded in the year 1831. In the same

year the world-renowned naturalist, Charles Darwin,left England in H.M.S. Beagle as a member of thefamous expedition to the Pacific. Between 1831 and1836 the expedition surveyed the South Americancoasts and adjacent islands, including the GalapagosIslands, and also the coasts of Australia and New Zea-land. Darwin recorded that the voyage was the most

It outlines thepeacetime activities of the association, some of which arenecessarily in abeyance now; it will therefore interestespecially those who have come into contact with the asso-ciation only during the war period.

important event in his life and it determined his wholecareer. The geological and other natural history notesmade by him during the voyage, especially along SouthAmerica, were the basis of most of his later works.

Exactly a century ago, Darwin prepared a shortaccount of the facts observed by him which indicatedrelationships between different living things and sug-gested a common line of descent. Also, in the year1842, was published his great work on "The Structureand Distribution of Coral Reefs," which gave the re-sults of his own observations of coral atolls in thePacific and Indian Oceans, and threw new light upontheir structure. He suggested that cores should be ob-tained by borings of such reefs in order to discoverhow deep the coral rock extended below the limit ofabout thirty fathoms in which the coral organisms canlive. The British Association was the first body to set
