The controversy which for a long time was maintained between Conrad and Gabb as to the age of the Tejon rocks of California, referred by the former to the eocene series, and by the latter considered to represent the uppermost member of the cretaceous (Division B of the California Report), can scarcely be considered to have settled the question at issue.

Page 110 - Wilcox found the parasites in four out of six birds examined. In the present specimen of a head a single worm is enclosed between the two laminae of the dura mater over the position of the interval of the cerebrum and cerebellum.
