3.— The BREAD we Eat. The BEEF we Cook. 4.— The BEVERAGES we Infuse.

5.— The SWEETS we Extract. The LIQUORS we Ferment. 6.— The NARCOTICS we Indulge in.

7.— The ODOURS we Enjoy. The SMELLS we Dislike.

8.— What we BREATHE and BREATHE For. What, How, and Why we Digest. 9.— The BODY we Cherish. The CIRCULATION of MATTER, a Recapitulation.
