13. A structure for testing odors of various materials as defined in claim 12 in which said conduits connecting the material compartments with the tester’s compartment are positioned in the lower portion of the compartments and spaced upwardly from the bottom thereof.

14. A structure for testing odors of various materials as defined in claim 12 in which said valve means for controlling each of said conduits has a control means extending externally of the compartment for the respective means.
