Book excerpt: Excerpt from The American Journal of the Medical Sciences, 1923, Vol. 165 Pneumothorax induced by injecting known amounts of air unilaterally into the chests of anesthetized animals produces effects that vary with the type and conditions of the animal and the rate of injection. Cats and dogs, animals of the thin pleura type, have mediastinums that are not air-tight. Man and monkey, thick of pleura, have air-tight mediastinums. Unilateral pneumo thorax is possible in man and monkey and impossible in cats and dogs. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
