Olfactory Research Apparatus

 

C.H. STOELTING - OFLACTORY TEST APPARATUS

This piece of apparatus was found with several tuning forks that were mounted on similar wooden bases. It consists of a vertical metal plate with a circular piece of material mounted in its center and with two holes drilled all the way through the material. It was finally located in an old Stoelting catalog. It was used to introduce separate olfactory stimuli into the right and left nostril of a subject. Two glass tubes ran through the two holes and into the subjects nostrils. The subject was prevented from seeing the stimulus as it was introduced into the tubes by the metal screen. It was manufactured by C. H. Stoelting., Chicago, Illinois.
