proving the present to be only a continuation of the Cretaceous period, I hold to be as untrue as the opinion that the Chalk is not the product of a Cretaceous ocean. So also with the arguments of those who urge and those who oppose the doctrine of Uniformity in the rate of geologic change; the Uniformitarian may push his advocacy to such an extreme that he departs almost as far from the truth in one direction as the Convulsionist does in another. Avoiding these extremes, we may believe in the longcontinued existence of continents and oceans, and yet admit that the Chalk is a genuine oceanic deposit; we may adopt the doctrine of Uniformity as our guiding principle in the interpretation of the past, and yet believe in the theory of Evolution.
