Dear Fred:

I am very pleased that you are willing to work with me on the revision of my College Chemistry, and I am looking forward to receiving some of your recommendations.

I shall plan on having some of the new material to you later in August, when you return from Amherst.

Copies of the Table of Contents, as planned at the present, and of the introductory statements for the six parts into which I propose to divide the book have just been mailed to you. I believe that the letter containing these was sent to the Department of Chemistry at Purdue.

I am not planning to make very extensive changes in the present chapters, and in accordance with your suggestion, you might look them over in the book itself, and send me your suggestions about them:

7. Weight Relations in Chemical Reactions (the chapter numbers refer to the first edition).

8. The Properties of Gases

10. Ions, Ionic Valence, and Electrolysis. (I am introducing a brief discussion of valence, about one page, in an earlier chapter. Accordingly the introduction, the first page or two, of this chapter will be changed. Also, a part of Chapter 14 Faraday's Laws, is to be incorporated in this chapter.)

11. Covalence and Electronic Structure. (Probably this chapter should be revised somewhat; I shall appreciate having your suggestions.)

12. Oxidation-Reduction Reactions.

13. The Halogens

15. Water

16. The Properties of Solutions

17. Sulfur

18. Nitrogen

19. Chemical Equilibrium and the Rate of Chemical Reaction

20. Acids and Bases

21. Phosphorus, Arsenic, Antimony, and Bismuth

22. Solubility Product and Precipitation

23. Complex Ions

30. Biochemistry

32. Energy and Chemical Change

33. Nuclear Chemistry
