Laboratory Apparatus and Chemicals; for Physics, Chemistry, Biology, Agriculture, General Science...Catalog No. 29

San Francisco: Braun-Knecht-Heimann-Co, 1929. Hardcover. Very good +. Quarto size, 552 pp. Issued by the Braun-Knecht-Heimann-Co. of San Francisco, and The Braun Corporation of Los Angeles, this 1929 catalog offers "supplies as are generally used in school laboratories" as well as "a limited line of agricultural equipment", along with "all instruments and equipment" manufactured by the W.M. Welch Scientific Company. The publishers also endeavored to introduce Historical Notes "in the hope that they may prove of interest and provide accessible biographical material" (n.b., quotes from the Introduction).

The catalog runs to 551 pages and is replete with drawings of various pieces of scientific equipment, the Index beginning with "Absorbent Cotton" and ending with "Zoology Specimens". A fascinating look into the apparatus needed to study the sciences in the first quarter of the 20th century, now almost one hundred years ago in time - but light-years ago in terms of knowledge.
