New York: Central Scientific Company, 1929. Quarto. Item #026637
601 pages. One of the most thorough catalogues of scientific instruments issued just before the Great Depression which began later that year. Both the Bakken and Hagley are among 8 scientific institutions that have copies. The publisher began to developed these items in 1923 and here they have introduced nearly all of the news and improved designs which were not available in the earlier issues. While many of the items pictured here are only available on the collector market, the hundreds of photographs and descriptions help to see the kinds of special scientific instruments which were available in the early part of the 20th century.
