Volumes contains materials related to three different courses listed on first sheet as follows: "Physical Chemistry / 1. Introductory course Prof. Daniels / Laboratory experiments / 2. Electrochemistry Prof. Watts / 3. Thermodynamics Prof. Daniels." Material includes handwritten notes, diagrams, and graphs, copies of typed course handouts, graded assignments, lab notes, and copies of some course examinations. Three loose sheets with answers to problems are laid in front.

Draft copy of Colburn's University of Wisconsin Master of Science thesis. Includes table of contents and numerous laid-in graphs and tables on blue print paper.

Clean copy of Colburn's Master of Science thesis. Identified on cover as "Heat Transmission in Gas Condensers." Contains table of contents and numerous illustrations and graphs printed on blue print paper. Unsigned and undated approval sheet at end.

Handwritten notes for class lectures and solutions to problems. Includes typed copy of Mathematics 110 final exam dated June 1928.

Contents consist of hand written lectures notes for three separate classes listed as follows:" I. Atomic Structures / 1928 Prof. Farrington Daniels / II. Molecular Structures / 1929 Prof. J.H. Williams / III. History of Chemistry / 1928 Prof. Louis Kahlenberg." The section on Atomic Structure includes a brief, typed listing of literature on atomic structure as well as copies of two exams given in the class.

Appears to be a draft of an article for the Bulletin of the University of Wisconsin , which appears on title page though without serial or volume number. Authors are listed as "Allan P Colburn / Fellow in Chemical Engineering" over "O.A. Hougen / Associate Professor of Chemical Engineering." Volume includes table of contents and list of illustrations (laid-in graphs on blueprint paper).

Appears to be rough draft of article for "Bulletin of University of Wisconsin Engineering Series" though no series or volume number is listed on title page. Authors are listed as "Allan P. Colburn / Fellow in Chemical Engineering" over "O.A. Hougen / Associate Professor of Chemical Engineering." Includes table of contents and table of figures, which seems to refer to the numerous graphs on blue print paper laid-in or stapled on pages. There are numerous penciled corrections and annotations throughout, including three loose sheets with differing versions of pages 63-66. There is also a loose sheet with what appears to be a draft version of the table of contents in pencil.

Included with this volume are three pieces of correspondence from Colburn's co-author O.A. Hougen, all dated from June of 1930, none of which appear related to the article. There is also a reprint of Colburn's article "Relation between Mass Transfer (Absorption) and Fluid Friction" from the journal Industrial and Engineering Chemistry , Volume 22, 967-977 (1930 September). Also included is a reprint of the article "Vapor-Liquid Equilibria of the System Acetone-Acetic Acid-Water" by Robert York, Jr. and Robert C.
