AUTOMOBILE-BODY REFINEMENTS AND AIR CONDITIONING

Dependability, economy, durability, speed, safety, appearance and riding comfort, are the factors considered by Dr. Moss in his resume of progress made in automobile development. Passing then to the problem of the effect of automobile riding on the health of passengers and drivers, he discusses air conditioning, eye strain and body posture while riding.

Carbon monoxide probably is the most important of the extraneous harmful substances in relation to air conditioning and an inexpensive investigation, using a carbon-monoxide indicator, is recommended to secure its elimination. Other harmful factors are temperature, relative humidity and motion of the air. A novel suggestion is made that rats be used experimentally in studying the effects of drafts on passengers. Studies to lessen eye strain and improve body posture are also desirable.
