ABSTRACT
Many zoologists have this doctor’s fault, with equally tragic results in a different sphere. While they remain obstinately deaf to rumours about unknown or supposedly fossil animals, these animals die out, some are already extinct, and we have lost the opportunity of studying them except as wretched remains. Their intellectual deafness may well have prevented the zoologists from finding the solutions to some prob lems they are concerned with. This thesis is amply borne out by the history of our knowledge of the animals of Madagascar.
