This adjustment was manifested by the formation of large numbers of new minute blood vessels in the lung. The immediate reaction of guinea-pigs to high altitude indicated marked sensitivity to low oxygen tension, but the capacity for final adjustment was exceptionally good, which is in contrast to the severe pulmonary changes occurring in cats living for a few months at a high altitude.
