Chemistry: The Science in Context, Third Edition was written and designed to help every kind of student, regardless of how they use the book.

NOTE: This book was published in 1936 as a manualto accompany several Gilbert Chemistry sets of the time.While some of the experiments and activities heremay be safely done as written, a number of them use chemicalsand methods no longer considered safe. Inaddition, much of the information contained in this book aboutchemistry and other subjects is outdated and inaccurate.Therefore, this book is probably best appreciated forits historical value rather than as a source for currentinformation and good experiments. If you tryanything here, please understand that you do so atyour own risk. See our.ALSO NOTE: The first 22 pagesconsist of the experiments that may be performed with thevarious sets and the table of contents. The actualcontent begins on page 23, in Part 2. Each part willopen in a new tab or window for ease of viewing.Cover - page 20.

Johnson has been associatedwith the Chemistry Department of Yale University since 1898. Hereceived the degree of Ph.B. From the Sheffield Scientific Schoolof Yale in 1898, and the Ph.D. Degree from Yale Graduate School in1901.

Since this later date he has been continually engaged atYale in the teaching of organic chemistry and in the promotion anddevelopment of advanced research in the field of organic chemistryand Biochemistry.About 75 graduate students have received their Ph.D. Degree forresearch done under his direction and these specially trained mennow hold positions in universities and industrial organizations inthis country. Johnson's publications in the field oforganic chemistry number nearly 300 papers, and his pupils whohave been granted the Ph.D. Are constantly contributing toscientific and technical journals in various lines of activity.Prof. Johnson is a member of the National Academy of Sciences, TheNational Research Council, The American Chemical Society, TheAmerican Institute of Chemists, The Connecticut Academy of Artsand Sciences and the American Society of Biological Chemists.At the present time he is holder of the Sterling Chair of OrganicChemistry in the Graduate School of Yale University.3.
